Having installed my turntable some time ago I have had time to familiarise myself with the accompanying problems of short circuits when the turntable is rotated aroun 180 degrees. After discussion with Richard Johnson of DCC concepts it was apparent that there was no other solution to the problem than to install a reverse loop module. I had balked at this previously due to the expense of the Lenz reverse loop module, however Richard was able to offer me something cheaper which fulfilled exactly the same function from the US.
I found the instructions on the Lenz website better than those provided with the US reverse loop module though as these offered some new possibilities. My initial thought had been to insert the reverse loop module into the track which went into the turntable from the main layout, however the Lenz instructions offered the alternative of wiring the module direct to the turntable itself and then electrifying all the subsidiary tracks so that my locos could all be powered all the time. This seemed the best option so that was aim of this project. What was to complicate matters is that I wanted to use Tillig code 83 track coming off of the turntable and I also have an access trapdoor which would swing upwards beneath six of the turntables tracks. This is the area which needs the work done.
My turntable is a Fleischmann one and is a fairly popular model. I initially installed the reverse loop module direct to the turntable without wiring any of the subsidiary lines and duly noted that if you placed a loco onto the turntable it would not move. It would only move in the module zone if it was driven in from a section powered by the main power bus. So on that basis I had to set out to power all the subsidiary lines from the turntable. The off ramps from the turntable are all code 100 Fleischmann track so I needed to convert code 100 track to code 83 and also to isolate the powered tracks from the turntable. Had I chosen to use code 100 track all I would have needed for this was code 100 isolated track joiners however being up for a challenge and preferring to use code 83 I had to use converter rail joiners to convert the track from code 100 to code 83 and then use code 83 insulated joiners to insulate the reverse loop module powered area from the main power bus powered track.
What I did was to put the code 83/100 converter rail joiner on first. The ones I used were Atlas and I wasn't very impressed. They were a struggle to get onto the code 100 track. If you are going to do this use the Fleischmann ones, I'm fairly confident they will be better than the ones I used. I then cut a two sleeper section of code 83 track to go between this join and the join which connected this to the main strip of code 83 track. The result doesn't look brilliant but I will tart it up with some additional sleepers so that I can minimise the gaps.
That's the basic track sorted now the next complication was that there is a hatch which is required for access on occasion as I am still doing scenic work to the far side of the layout. Although this is the narrow end it is still two and half metres wide and a bit too far for me to reach. I intended to put the hatch on hinges so it will swing open. The problem I had is that six lengths of track run across this hatch. Four came completely within the surface of the hatch and so were easy to sort, however two went diagonally across the corner of the hatch and presented a problem. Having no desire to cut an L shape into my track I resolved this by adjusting the spacing and straightness of the track so that all six were contained within the surface area. This was achieved without having a regular spacing between the ends of the track but a compromise had to be made in the interests of functionality. The track was wired and solidly fastened down to the baseboard and then cut at the appropriate place. The tracks which were cut were wired at the top and the bottom so that both halves were connected to the main power bus.
Having done all that I checked the operability of it and it works fine. Now I can have all my sound and light locos makings noises and shining their lights as they sit there by the turntable and no more shorts! When you have a three year old who loves to work the turntable and short out your layout frequently it certainly does give you the motivation to get on with things like this.
bending of tracks at edge doesn't appear too noticeable.
On another note I got some of that Siliflor grass mat stuff from International Models to check it out. It is very good although expensive. Probably best to save this for close up areas where people are very proximate. Here are some shots. It looks better than you see in the photos as, probably because it's synthetic, it has a shine which has come up because of the flash. Under normal lighting you don't get this.
Having had a bit of time to try our all these accessories I have been finding a bit more about them. Here are some of my findings.
The Tortoise motor also has an adjustable fulcrum on the side which allows for adjustment after instalment. The Tillig one does not. Once the Tillig motor is installed, you can only adjust the positioning by moving the points, which is not ideal. if your track is already in a set position and you cannot move it, you will be in the unfortunate position (as I am) of having to use the trial and error method of moving the motor, fastening it and then checking it to see if its movement is correct. I find the ability to adjust Tortoise motors once installed is a great asset.
Over the last month I have found that the Tillig and Tortoise motors have been 100% reliable, which is exactly what I want. The Low power Peco ones are a bit hit and miss so they will have to go.
I have decided that the Peco point motors will not do at all anywhere where the movement can be seen. I have been so impressed with the point motors especially the quiet Tortoise that my intention now is to use Tortoise where space allows and to use Tillig where there are space restrictions.
I was a bit put off the Tortoise initially due to the diode aspect of things but it's not a problem once you establish exactly what you are looking for and where to find it. I got mine from Dick Smith Electronics for cents.
I had noticed that most modellers prefer to have LED display with all their points on with a track diagram. This makes things easy to follow and give an indication which way a point is set. I really have no inclination to do this at the moment as my layout is not really complex enough to warrant it. I can see most of the points fairly easy from most of the positions I will be in when controlling the layout and I am quite happy with the point and route control on the ECoS, so I will stick with this for the moment.
I will set up some more shuttle lines though as I am very happy with this feature.
In regard to point decoders LDT do a separate point decoder specifically for motorised points such as Tortoise, Conrad , Fulgurex and Tillig (Pilz)
in this diagram Tortoise are wired as for Conrad.
The Lenz LS150 has the benefit of being able to operate both snap action and motorised points.
What is interesting about the LDT M dec-dc is that it has two inputs for each decoder instead of the traditional three that most other point decoders have. This costs euro 48.50 and handles four point motors. The Lenz costs euro 45 although I can get it for 38 euro and can handle six motors. The Lenz also has the ability to predetermine the time of power aplication to the motor. The LDT M-DEC-DC applies the power for 10 seconds then cuts of the voltage according to the instructions.
Another thing I have noticed with the Lenz LS150 is that you have to be careful when programming it. I found that outputs 4 and 5 weren't working, sp I initially assumed that it was because I was using older Peco snap action motors. I changed these for Tillig motors and they still wouldn't work. I did all sorts of diagnostics until I discovered that resetting the point addresses resolved the situation. While resetting the time of power activation I must have inadvertently changed the addresses of outputs 4 and 5.
I was not happy with the peco snap action points that I had installed so I pulled them all out of all visible areas and am now installing Tillig where space is tight and Tortoise where space allows.
In selecting appropriate occupancy detectors to use with the ECoS, I initially opted for the Veissmann 5233 which was an adaptation of the Veissmann 5217 S-88 for two rail DC DCC use. It has since transpired that there are issues with this particular occupancy detector in regard to the ECoS. It seems that it can be used but it cannot be the last occupancy detector in the chain. I have resolved this by buying an LDT RM GB 8 to be the last in the chain. These seem to be the occupancy detector most favoured by ESU for use with the ECoS. There are four recommended for use in the ECoS manual however two, the Maerklin 6088 and the Viessmann 5217, are for use with AC current & Motorola only and the LDT REM DEC 88 is for use with reeds so that leaves the LDT RM GB 8 as my preferred option.
Setting up the shuttle lines
The Occupancy detectors are initially to be installed on the shuttle lines. In future after testing I will extend this to the main lines. For these lines I have set up a couple of raised designated lines specifically for this purpose. The scenery when finished will show mountainous terrain and will be Swiss at one end and Scottish at the other. I recently decided to extend my UK outline part of my layout and I thought a gradual progression from the Highlands of Scotland to the Alps might be the way to go.
For track I will be using Tillig code 83 Elite as I was very impressed with its looks. These lines are at close to eye level so detail is crucial in this area.
I have decided to have two small terminus stations at each end. These will each have a siding so that there can be an option of which loco to use on the shuttle service. In order to power the points I will be using Tillig point motors as they are the most appropriate for Tillig track. They will be connected to Lenz LS150 point decoders. The shuttle lines will be at close to eye level and will be excellent to showcase highly detailed loco motives and running stock. I had initially intended to run my Bachmann Turbostars on these routes but the length of them relative to the length of the shuttle lines has me doubting whether this is such a good idea. Smaller locomotives would be more appropriate and this is an area in which my running list is severely lacking. As regards the Swiss end the Croc is ideal. It is relatively short and can easily travel slowly as per the prototype with cargo. The Turbostar however should be going faster which is not an ideal option on a route which is only four or five metres. Comparing a Turbostar to a length of track as shown below shows it just comes with one strip of Tillig track length. I have added a small bit on to that block of track as this will be the trigger for the decelaration and it is crucial it does not miss this!
The other problem with the Turbostar is that it will have current draw from all three coaches and the track with the S88 contact, in order to be triggered, needs to be slightly larger than the loco or coaches which will trigger the contact. In the case of the Turbostar this will be about a metre which is quite long when you consider that I must have at least two of these track sections on the shuttle line. Some experimentation will be necessary before this is settled.
First step is to enter the s88ís into ECoS. This is pretty easy. You must ensure that you insert the connector the correct way up. Ensure that the cable hangs downwards. You tap up the appropriate screen for S-88 entry.
You then enter what type of S-88 (e.g. whether it is 8 or 16 port) it is and then tick the box.
Then lay the track connecting the S88ís to the track.
One piece of advice is to ensure that the current drawing train or loco which will trigger the S88 will fit in its entirety into the track section being monitored. One issue I have already come up against is that the locos or units which you will run will be of variable length. E.G. I intend to run Turbostar DMUís and also SBB Crocs. These are obviously of different lengths and the stopping distant needs to be taken into consideration for the shuttle line. How I have got round this is by having each single piece of track wired for DCC. For the regular DCC track I have wired each rail but for the rail which connects to the S-88 I have in some areas split the track in half and inserted an insulting joiner. The reason for this is so that once the track has been ballasted I do not have to lift it to apply new contacts or insulators. The contact wires have already been installed and I can connect them up underneath the baseboard in a combination which can be adjusted to accommodate the length of train or loco which I need to be detected. Track laying for this sort of venture is more laborious than normal as there is a further variable which requires consideration. To connect up the wires after track laying, all the straight DCC rail wires can be tied together and connected up as one. The S-88 connected rail wires can be varied according to the size of the loco you need detected and where you want it to stop. Yet another factor for consideration here is the stopping distance of your loco. I have found these to vary considerably and you may be surprised how short or long a distance it will take for your loco to stop. My K.Pev P8 pretty much stopped dead in its tracks. So I can allow a distance of 10cm for it whereas my Bachmann Turbostar requires a longer sort of distance to stop, so this needs to be taken into consideration prior to laying the track.
I will also try to have the points triggered by S88ís too in order to test this feature.
Another factor is consideration of which S-88ís to use. I have compared them both and there are some points worth pointing out. The size of the units are substantially different. The Veissmann is compact and takes up less space. However the cable for the Veissmann is very short and will have to be sited very close to your controller. The S-88ís have to be connected in a daisy chain manner. You can buy an extension cable should you require it from several companies including LDT. The LDT has a longer length cable which is a lot more flexible. Which ever you choose it should be borne in mind that the LDT will have to be the last in the chain as there is a problem with the Veissmann in this respect.
The Viessmann S-88 has plastic plugs to hold in the connecting wires with whereas the LDT has screw in blocks. This may seem trivial but wait till you forget to have screwdriver handy to find out the difference this makes. Also worth considering is what you will use when you inevitably loose the provided plastic plugs.
I have used the choc block connectors for this as recommended by David (DWB) as the shuttle routes are something which will be adjusted and reconnected periodically depending on what I am running on them.
Another issue for consideration is that because of the short cable length keeping the s88ís located close to the controller is that you will have to run a long length of wire from each track block which you want detected to the controller. Buy plenty of wire before hand if you have a large layout, you really will need it. You could buy an extension cable or two to take your S-88 close to where it is needed but then you will have the same problem again because your next area of occupancy detection may be some distance from the first and you will need even more S-88 extension cable to connect to the next S-88. I preferred to keep them all close to the control unit.
Here are a couple of views of the track from one end. The terminus shown will be a West Highland station which will be scratchbuilt at some point.
Here is the other end which is a Swiss mountain station.
Having constructed my lines the nest thing to do was to wire them up. This was easy enough although be prepared to rewire this over and over again as you try to get the loco or train to stop where you want it. The only real problem I had installing the S-88ís was the polarity. I got a short circuit first time around. A quick switch round of the wires got this sorted.
I found the Veissmann S-88 more limited than the LDT in some ways. The LDT has two power inputs so you can use it to cover two track sections. I am using the LDT to cover both shuttle lines. You can get by with as little as three detected sections on a shuttle line. The Veissmann does not have this facility and will only allow you to do eight sections right next to each other. The Veissmann also says that if youíre going to have detected sections next to undetected, then you must install a module, which consists of diodes and resistors to prevent interruption of the signal. The LDT doesnít seem to need this. I also didnít like the plastic plugs in the Veissmann as they have tendency to fall out after use. I prefer the wire screw in blocks of the LDT.
The length of the cable with the Veissmann is far too short. It can only be three inches from the ECoS at most!
One suggestion which may be worth considering when setting these up is that you will need about five times as much wire for the S_88 detected rail as you will for the undetected rail. The undetected rail is just a standard power bus and can follow the track along. The detected rail however has every detected section requiring a wire going from the track back to the S-88. Bit like the difference in between the circumference of bicycle tyre relative to the sum of the length of all the spokes. For the centre section, unless you want anything else going on which requires detection like points are signals, you can just connect up all the wires for that centre section to a common module port.
The shuttle lines in operation.
Having done all the wiring up and installation it was now time to get a train going. My test pilot was to be a Scot Rail Turbostar. Turbostars were one of the DMUís I had in mind when I thought of the shuttle feature so I wanted to see how these went.
First you set up your shuttle line.
You go the Shuttle line menu and either add a new one or select one you want to edit. These are listed by name.
This is the screen which opens up and in this screen you enter the name of the route and specify the time it will stay in the station or terminus.
This box allows you to select the S-88 module.
..and this one the port of that module.
After that just confirm by ticking the box and it will then close.
Next step is to select a loco and start it to run at the required speed on the shuttle line.
Then from the drop down menu select shuttle line, this will trigger a new menu with a list of your shuttle lines. Select the one you want and it then goes into shuttle mode. You cannot then control the loco until such time as you terminate shuttle mode. You can have eight of these going at once.
Since I set these up I have done a fair bit of tweaking and as I have been working out there most of the day, I have had a Turbostar and a Swiss Croc shuttling back and forth for hours without any problems, other than the Turbostar decoupling itself once which is unrelated to the system. They seem to be able to carry on perfectly well as long as there are no issues with the loco or track.
Some thoughts for consideration are that if you are going to set these lines up and intend to use different locos and units on these lines I would recommend that you take each final length of track at each end (and if you are using a DMU or EMU you may need to make this two lengths) leave one rail complete and the other rail which you intend to use with the S-88 divide into four and use isolating connectors to rejoin them. Solder a dropper to each isolated piece of rail and now you will be in the position that you can adjust, under the baseboard, the length of rail and location of the rail which will detect the loco. Having used two very different locos to check this out, if you want to have the loco stop in the station precisely where you want it to, you need to adjust where it gets the message to stop. If you do not do this before you ballast your track you will have to rip it up every time you use a substantially different loco or unit.
I am finding out that it seems that the loco stops when it leaves the detected track that you set up on your shuttle line . I still have more to find out about this system to get it down to a fine art. I have got pretty close with the Turbostar and can get it to a couple of cm of the buffer stop.
Iím quite pleased to have got to this point where the shuttle lines function smoothly as it was major consideration in buying the ECoS over a budget system. I will now see where I can set up more shuttle lines so I can allow the trains to run themselves. These lines are more suited for DMUís, EMUís and the like as the return journey will involve a loco pushing the train rather than pulling it. This is no big issue, just a point for consideration. Overall I think this is an excellent feature which is ideal for terminus to terminus layouts.
Points motors and decoders
In addition to the shuttle lines I have been experimenting with motorised point motors. I actually had to install these before I could get the shuttle lines up and going as they are part of the lines. For the motorised points I was going to use a Lenz LS150. I installed the Tillig ones first and they are very good I have to say. I used the Tillig point motors with the Tillig track as they are best suited. These were a bugger to install but this is not a problem with the motors. It was the location that was the problem. I didnít have enough room to get a screw driver in so I had to use one of those special small screw drivers, the blade of which was a bit too broad so it kept slipping out. This took ages. The second motor I decided to remove the base board and lift the track and then install it. Pays to think ahead with point motor installation. This is the only area on my layout with such restricted access so fortunately I donít have to deal with this again.
Preparation of the Tillig motors is easy. You remove them from the box and choose which of the two pins suits you and insert it in the slot. They come set for a 6 mm switch which is correct for Tillig points, so no adjustment necessary there. I found the instructions a bit hard going so itís just as well I didnít really have to consult them much. The Tillig motors are easy to wire up, they are mentioned in the Lenz booklet as Pilz motors and can be wired as simply as snap double coil motors. No messing with diodes, somebody appears to have thought ahead and installed them already. Allocating addresses was straight forward and as per the Lenz LS150 manual.
However although I set the pulse duration to about two seconds on the ECoS it only seemed to be a fraction of a second. I figured that not only do you have to set the pulse duration on ECoS but also on the LS150. There are instructions in the manual and this sorted the problem. This could have been a problem if I had used the LDT point decoder as I donít remember them mentioning anything about setting pulse duration.
The Tillig motors are great but how do they rub up against the old favourite, the Tortoise? Well this photo should tell you a fair bit. Look at the difference in size.
The down side of the Tortoise compared with the Tillig is that you have to;
Locate and buy diodes,
Mess around bending wire,
Add three inches to clearance considerations,
Do some soldering.
I actually found the Tortoise easier to install but that was because I had four feet of clearance under the layout where I was working instead of three inches. It makes a big difference. Installing the wires was more fiddly as you have to ensure you have your diodes the right way around.
Are there any pluses to the Tortoise motor then? Well thereís one big one which may well be at the top of many peoples list of priorities; itís considerably quieter than the Tillig.
I quite liked both point motors. For domestic purposes I will go with Tillig as they are easier wire up and take up less space. However for shows I can see why people would choose Tortoise.
In regard to point decoders, I like the Lenz LS150 best as it is more compact, allows you to set pulse duration and has far more comprehensive instructions.
So now having done this I can get on with some scenery to make this area look like a mountain railway.
Well after finally getting the LDT function decoder to work it seems that I was looking too deeply into it. It is actually easy to program and this was the problem as it was easier than I expected and the only issue that needed addressed was to reverse the polarity of the DCC power inputs.
With the LDT S DEC-4-DC to program it you set up your route with the four points you wish to be controlled as shown below. You then press button S1 on the decoder and it goes into programming mode indicated by the first point switching every 1.5 seconds.
Switch the first point and the decoder programs the point decoder. If this is successful it is indicated by the point switching more rapidly. Press S1 to confirm the programming and youíre done. Pretty easy now I know how.
This screen is where you enter in each accessory.
There is a fair selection of accessory ikons which you can use to identify your points, lights, signals etc.
You can select switch or pulse. Donít know why this picture came out on its side.
With pulse you can specify the duration of the pulse. With the latest software download version 1.0.6 you now have several shorter pulse intervals of 100ms, 150ms and 200ms to choose from too.
In order to set routes you select a new route screen. You then press the edit function button which is fourth in from the left. This makes the screen background go black and you can then enter new accessories into a route.
To add an accessory to the route press the ikon where you want to put the new accessory and a menu will come up. You then press on select from list.
A list of all your entered accessories comes up and you select the one you want. Once the route has been finalised it looks like this below and can be incorporated into other larger routes.
In this advanced route screen you can specify the time delay between triggering of magnetic accessories and also whether you want them to be triggered by S88ís and which S88ís you wish to trigger them.
I used Peco low power double coil point motors in conjunction with the LDT S-DEC-4-DC and the results are good. I intended to use Peco point motors in the sections which are not visible for reasons of economy. Above board I will use a combination of Tillig and Tortoise depending on which I find best to use.
Well not everything goes according to plan. I had a couple of set backs this week which I wasn't too pleased with. I also had some successes so it sort of balanced out in the end.
I had previously had a problem with setting four digit addresses. I had confirmed that I was doing everything correctly and was coming round to the suspicion that something was wrong with my ECoS. I then tried to program the locos one more time using the simplest method and lo and behold it worked first time. I donít know what I did wrong as Iím certain that the method I used was identical to that I used first time around. Maybe the ECoS is tempramental in some espects.
Here are some of the programming screens to show how easy it is to program locos with the ECoS. Since I first mentioned this I have learned a hell of a lot more about programming and CVís and so on so I am a bit more clued up on the significance of some of these features.
This screen shows the CVís related to starting stopping tines etc.
This screen shows the addressing CVís. In a previous discussion on the programming screen regarding the binary tick boxes method pf programming CV 29, David mentioned that this would make setting CV 29 settings easy. Well this makes it easier still as it tells you the CV 29 setting and you tick the box. So if you want CV29.5 you just tick the box and input your four digit address then press the track symbol at the bottom.
To set or use CV 1 you untick the box. Simple eh?
CV 29.2 merits its own screen. This is where you can turn analogue on and off. There are additional pages where you can set volume and sound parameters, motor parameters and function parameters if you really want to customize your decoderís settings.
Now having had a failure and then a success we now move on to the reverse.
I did my first 21 pin decoder installation. This was remarkably easy. I wish I had set my stop watch. It was probably completed in under two minutes.
Here we are at the beginning of the operation. I have taken the cap of the tender to show the inner circuit board. The 21 pin decoder is at the front on top of the foil bag. The huge box at the top left, which is almost as big as the loco, is what the decoder came in! The box contained a decoder and an instruction booklet! I have shown a Lenz Gold in the picture for comparative purposes. All I had to do was unscrew the circuit board at the corner and remove the blanking plug.
Then stick the decoder in place. It can only really go in one way so once you have figured that out you are done. Just screw the board back and clip on the tender cover and weíre off.
Well that was the theory anyway, in practice this wasnít the case. I put the loco on the programming track and read in itís settings. This seemed to go ok. Assigned addresses both long and short. The trouble began when I tried to run it. It didnít move! I prompted it a bit and no kidding it just stuttered erratically. Gutted! Certainly not what I expect from Trix. I removed the decoder and reinstalled the blanking plug and the performance was the same it appeared the loco was the problem. I did a few checks and partially dismantled it to see what the problem was. It seems the wheels are badly tarnished and there seems to be the possibility of a loose connection some where. This was a brand new loco bought on EBay. It is the second time I have bought an allegedly new loco from EBay and had a problem. I am starting to wonder if some dealers are selling off returns, badly stored equipment or back of the lorry jobs on EBay to evade dealing with the resultant complaint issues. So that would be a repair job then I guess!
I also finished a bench for my ECos to sit on. This should keep it safe enough from prying little hands.
I have now accumulated a reasonable amount of point motors point decoders and S88ís. Well this week I finally decided to start wiring up all my switch motor and decoders. I have a Tortoise, Peco low power double coil and Tillig motors at my disposal and LDT S-DEC-4-DC and Lenz LS150ís to try out with them to see what goes best.
The area I am going to install them in is the four point connection between the outer and inner rings just at the back of the photo below.
I decided to go with the Peco low power twin coils and the LDT S-DEC-4 DC. I was going to use the Peco point motors for this particular area as it is not visible to the viewer and is being motorised only because of its inaccessibility. I put the motors above board as they can easily be hidden by scenery where they are located and it makes them more accessible for servicing. I wired everything up as advised and then got down to the programming aspect of things. The instructions are in English but if you are familiar with Googles language translator you will be aware that some translations are better than others. The instructions said to press the programming button and then point number one would switch every 1.5 seconds. This happened successfully. The next instruction was to switch a point and it would then take on that address. I probably spent an hour or two trying every variation on that theme and still didnít get it to work.
With the assistance of the ESU forum, I now have some valuable new information top be going on with and will try this out tomorrow. It seems that a few people have had this and other problems with the LDT switch decoder in conjunction with ECoS. ESUís advice is to wait on their Switch pilot (which they say will be priced around 30 Euros) and this will be 100% compatible. This was my original plan but I got bored waiting on it coming out. I can always switch the switch decoder later. I will play around with at the weekend and have a go with the Lenz LS150. The Tortoise motor will require a couple of diodes so I will have to get those sorted our before trying that out. The Tillig ones shouldnít be a problem but before I go laying track on my upper level shuttle line I need to sort what will then become inaccessible behind it.
The ECoS Support forum is quite helpful I have found. Even though it is primarily in German I have used the Google language translator to decipher many of the threads and have found much helpful information. It has been criticised by many for being in German but letís be realistic ESU are a German company and their customers are mainly German so it is the logical place to start. I tend to post in English and German and have found that people will usually respond in English. Probably because my Google translation in German is so bad they have taken pity on me. With the ECoS being so new and its limits and quirks still being discovered it is very important to have a forum to share information to help with the learning process. Which is why we are all looking at forums in the first place.
PS as a bit of a post script I went out this morning and reversed the polarity of the DCC input to the point decoder and it worked first time. It now works great so I will do a short follow up next week on points and route control.
