Al,
As mentioned already, the most common DCC systems in O Scale are from Digitrax and NCE. MRC does have a higher amp system as well if you're familiar with the Prodigy line of products, look for the Elite model offering 10A. MRC has a nice comparison chart located here - http://modelrectifier.com/train-controls/dcc.asp Thank you for the chart,it was very helpful in giving me a starting point. it seems they only present 1 10 amp system,though the 2nd choice,going from left to the right seems like enough of a system for me,except for the amperage & possibly a wireless remote. The remote I'm not sure about anymore.
A couple things to keep in mind, the 1.6A and 3A systems may be able to power a couple O scale trains but as you add locomotives, sound, smoke (if you use smoke units) all will create a spike in your Amperage as well as increase the continuous Amp draw. Certainly you can create some power districts, manage where you're locomotives are on the railroad, etc.. Now you're adding more complexity to wiring and operation.
Personally I wouldn't look at anything lower than 5A even for your planned operation, because you'll want something that you can grow with if your plans change.
Another important factor will be what system do others around you use? They may be able to offer further support as you learn the system. I have no O scalers around me so that's what makes transitioning to O scale so difficult-I'm winging it by my lonesome. Don't take that wrong you modelers on this site are GREAT!! It's just having someone to talk to personally & have to help in person with things I can't do releaves much pressure that can fester for months.
Look for which system offers the throttle that you like the best, offers wireless or wired operation? I need wired as I was having my 1st bit of fun with a 10 car train the other day,butsince I serve as engineer&conductor,I can't be at both ends of the train which is a problem. MRC seems to have the only wireless but I must be missing something here,at least with the info sites on NCE,MRC seemed the most reasonably priced in the 10amp system for a wireless. If my poor ol' brain recalls correctly,to get wireless in NCE a separate connection box has to be bought.(?)
So based on what I've heard from you a couple suggestions would be
NCE PowerCab + SB5 - Good
NCE PowerPro 5A - Better
Digitrax SEBX Super Empire Builder Xtra - Good
Digitrax SEBXD Super Empire Builder Xtra Duplex Radio Equipped - Better
In terms of where to install the DCC decoder in the GP15 carefully open the hatch where the dynamic brake fan is located, or the non-dynamic brake hatch, and you'll see the plugs for the DCC decoder. I often find it easier to install if I take the whole body off the chassis. That allows easier access to all the plugs, wires, etc... Especially for those with larger hands, fingers. Is there a plug in socket inside? I haven't looked close,but seems like there was a plug on 1 end of the diesel& some very short wires on the other end,the purpose of what each is remains undetermined,will need to have a closer look maybe take some pic's. Also,sound will be VERY IMPORTANT to me,so what type of sound decoders should I be considering? Here are effects I'm looking for: horn&bell,coupler clash,engine air build up release sound,wheel noise,,(not clickety clack),air burst when airlines separate,cut lever noise when uncoupling,prime mover noise when the engine speeds & slows.
Thanks again Mike DeBerg& to all for your inputs.
