Hi Bigdutch and welcome to the MRF.

The question of which point motors to use is one that pops up regularly and there is, unfortunately, no definitive answer.

I must, however, agree with Brian when he says that slow action motors such as Tortoise are superior to the traditional solenoid type of motors both in their reliability and their prototypical speed of movement. Such superiority does, however, come at a price. Tortoise motors cost about £12 each whereas solenoid motors are about a fiver.

Personally I use the Seep PM1 point motors which cost about a fiver each and include the facility to change frog polarity. With Peco you buy the point motor and the polarity change unit separately which costs more.

Hope this helps.

Hi Bigdutch.

I'm attaching 2 wiring diagrams for the Seep PM1.

The first is for a simple 'stud & probe' type of control and the second is for a more ambitious (& more expensive) switched point control system using Masterswitches from Richard Johnson at DCC Concepts and bi-colour LED route indicators. Both are for a DCC system.

The latter diagram also shows the modifications which are necessary to electrofrog points to isolate the frog and control its polarity.

Is this the sort of thing you are looking for ???

It all depends on how many points you have on your layout. If you only have 5 or 6 then the price differential is not so painful. If, like me on the other hand, you have over 30 points in your layout it becomes a factor to be considered.

The cheapest I've seen Tortoise motors is £10 each compared to Seep PM1s at £4.60. i.e £300 plays £138. I just can't justify the additional cost.

At the end of the day though you get what you pay for.

You pays your money and you takes your pick.

Aaaah but compare it to the price of a Seep PM1 and it is not so cost effective.

You don't need a mounting plate for the Seep. It already has screw holes for fixing in position and, AFAIK it is possible to run more than one device off the auxilliary contacts.

I acknowledge that slow action motors are better but, for those who are perhaps embarking on their first layout or for those with budgetary constraints, I still believe that the Seep PM1s are the best value for money around.

Sorry to disappoint you Bigdutch but you will need a separate 16 v DC power supply for the point motors. You will also need a Capacitor Discharge Unit (CDU) to boost the power to the point motors. Here's a little diagram showing how Seep PM1s can be wired though there are several other alternative ways of doing it.

If you are going for the slow action type of points you will not need the CDU.
