I recently purchased a Dynamis DCC on recommedation of local dealer. He has installed installed decoders into three locomotives. I have a test straight as it suggests in the manual (not connected to the layout), and I can get the loco to go backwards and forwards. That much I understand but the rest is a mystery.

I think the documentation with Dynamis and the Decoders is really poor for someone who has no knowledge of the subject

I have read through many articles and have become more and more confused. I dont mind a challenge and am prepared to learn. Can those experts give me simple guidance, without jargon. I am sure I am not alone in my state of bewilderment.

Background - my model railway is in a loft conversion (self built), 16 m around the room principally Hornby OO. I have 7 locomotives all set very loosely in the 1950's (yes I know predictable). I have in preparation put in place (bell) wire all around under the circuit to ensure no dead areas when I convert to digital. I have read in one thread this is not sufficient, and should use household cable with just short tails of fine cable, is this correct? Would 0.75 or 1mm be more appropriate?

Lighting on the circuit, and turnouts I would like to be digital in the future. I am reluctant to have more locos with decoders until I understand the potential of dcc (sound being just one I have read about) , but at the moment using the locos correctly is the first step.

Thank you - Ray

Thank you for the guidance to date, but why is it such matters are not explained with the instruction books?

Thank you also for the welcome, much appreciated - I am sure MRF is going to be most useful.

The advice offered gave me confidence to have a concerted effort to get digital started. I used the advice of disconnecting the existing DC supply, and connected DCC to the down line, and to my delight achieved independent movement of three locos.

Only having three locos with decoders I reconnected DC to the up line, and was able to run the non decoder locos. So my circuit is now operational and utilising dcc in a small way.

Satisfied with that progress I am going to install three pairs of bus, 2 for power to the main tracks, 2 for points motors, and two for other accessories in the future. I have chosen to go with 32/0.2 which I will purchase from Maplin. I soldered my existing droppers to the bottom of the rails before ballasting a year or two ago. The droppers are 16/0.2 and these will be connected to the 32/0.2 power supply to the main track. After re-checking polarity I will solder the wire joints as I am not likely to ever change the layout.

In the end I ignored all details about CV's. I simply changed the name a number on the controller. I am sure there is much more I could do to improve the running, but I am not in any particular rush. Thank you MRF for this push in the right direction. Whats next?

Mike - Can you please explain the DPDT rocker switch to enable both DCC or DC running, at this stage I guess I can still incorporate anything.

Once again more useful information. Thank you. I also took the opportunity to look at Hawkers Bridge - a facinating tale, and a layout to envy.

Good point about isolating the locos before switching over. So much to take in. Thank you again.

With the knowledge the forum has shared with me I have installed the BUS and connected all the droppers using a variety of connections as I carefully checked the polarity using one of my original Hornby DC controllers. Each time it shorted out, I switched it off to reset, then tried again, a relatively simple exercise. I then tried running one DC locomotive to test it all ran correctly. Total success.

I then connected the DCC controller and within minutes was able to run simultaneously three locomotives. Flushed with success I took my other locomotives to my local dealer to have decoders fitted. His view is that sound decoders are still expensive, and not realistic and it is better to wait a little longer. Unfortunatley my skills are not developed enough to fit decoders myself. I will prcatice my soldering ability as I finalise the connections to the BUS.

Whilst at the dealers we discussed the turnouts. Mine are all standard Hornby, and at present I have six with motors. I took the dealers advice to keep the Hornby point motors, and purchased a Lenz decoder. That is my next project, and will be run from the seperate BUS installled for that purpose.

I beleive it is important to listen to the advice of ones local dealer as he will be the guy who will be sorting out the problems should it all go wrong. Before I start the installation has the forum any tips before I proceed?


My thought for pursuing this very simplistic thread is I beleive there are other novice modellers who have modest ambitions, limited time and budgets, and would also benefit from the basic information I seek. Thank you to the forum, for the help, and keeping it simple.
