DCC for Proto

I have just been invited to a group that runs DCC. I have no DCC locos but i do have several new Protos that can be set up to run DCC. My question is if I convert them to DCC is it a hassel to change them back to regular power after I run with the group.

Thanks

 

There is no need to convert them back. Most decoders support DCC and regular DC automatically. When you place the locomotive on the track it will sense whether the power on the track is DCC or DC.

Some decoders (Atlas Dual Mode Decoders come to mind) require that you move a jumper plug on the decoder board to change between DCC and DC Operation.

If you will post what locomotives you are thinking of putting decoders in, I am sure that people will make suggestions on appropriate decoders.

Thanks David

 

The NCE P2K decoders are a good place to start. You need to replace the light bulbs at the same time as you put in the decoder. The Proto locomotives come with 1.5v bulbs and DCC sends 12V to the bulb. While there are several fine points, the quickest way is to use a 14v 30ma bulb.

Now when you run it on DC - the lights don't work and it's been my experince that when in DC mode, the locomotive might not always go in reverse when you want it to... It's not a big deal, but if you are going to be switching between DC and DCC alot, the Atlas Dual Mode might be a better way to go...

 

Headlight bulb replacement is not necessary. If you use the Digitrax DH163LO decoder which is specifically designed for P2K locomotives, it has resistors built in that restrict current to the bulbs. If you use another decoder, all you have to do is place resistors in series with each of the bulbs. You can change bulbs to 12-14 volt type if you so desire but it is still recommended that you place small value (22 ohm) resistors in series to limit the current at function turn on. This protects the decoder from burning out the function transistor.

Thanks Rob and David,

Please remember that what I know about DCC at this point you could fit on the head of a pin. However I think I need to do some reading on the two decoders you both mention before I make my final choise. So it looks like the branch like for me for a while david until I make up my mind.

Thanks again guys

 

Shannon,

I might suggest that you come to the operating session and see if you enjoy it enough to want to come back again. If you do want to come back, then decide whether and what decoder to install in your locomotives.

By the way, I have more than enough locomotives for everyone to use during the operating session. Most of the people in the group run N scale at home and/or at their clubs but when they come to my operating sessions they run my equipment. Some have started buying their own HO equipment just for the operating session.

Shannon,
I would be interested in your thoughts on dcc after you have run it.

I had planned to bring cars only the first time and just watch. I may bring one or two locos for the branch line but that would be all. I want to learn about the layout and the way you conduct your sessions before I dive head long into DCC for my layout.
