So, I have another engine, that my father-in-law bought for his little girl, whom I married, that I would like to convert to DCC, anyone attempt and if so, which decoder did you use and are there any youtube's out there?

I acquired a Bachmann Spectrum GP 30 Diesel Union Pacific #731 and would like to add DCC to it as that is the direction I am going for my permanent track build.  I am pretty technical, I just can't seem to figure out what decoder I need for this loco.  Thanks.

Hi, I am new to HO modeling and just picked up a number of trains, cars, buildings and so on with the intention of making my own HO DCC set in a spare bedroom.  While running the Bachmann Spectrum 83003 Amtrak Acela HHP-8 Locomotive w/ ESU LokPilot DCC that was part of the haul, and in doing further research, I realized that the passenger doors on this loco may open via a command from the NCE PowerCab DCC I have. Further, I was wondering if this particular loco has sound. So, question one I guess is does this loco has sound and if so why wouldn't my DCC be able to turn it on and second how do I get the doors to operate?  Thanks.
