I'm thinking of making the switch from DC to DCC so that I can run double header trains with rear end pushers as was common in the era (1880). So I'm at the beginning of the DDC learning curve. I have found Bruce's Column in MRH to be very helpful as have the various manuals and web sites of the various manufactures. My engines (that I will have to add decoders too) have different motors and gear box setups that does not allow them to be ran together realizably. As i understand it (I think) the two lead engines you make a consists and the rear helper as an another engine/train.

  Hi All, I'm putting a decoder in my TT scale loco and was thinking about consisting it with a stationary sound decoder so I could add a sub woofer and speakers under the table. The loco is so small I don't want to add an onboard decoder right now but it seems like it should be pretty easy to rig up a spare soundtraxx under the table?   Does anyone know how I should connect one? Would the decoder need some kind of load on the motor wires to work correctly? How should I connect the decoder sound output to a sub woofer/speaker setup?

So for the past week I've been trying to install a dcc decoder into a ho ahm 0-4-0. I've insulated just about everything but it keeps shorting out. I've removed the motor. Insulated wheels from the frame but just can't figure out what I'm not doing. Has anyone attempted to add dcc to one of these. Because this is one of those projects I might just leave be. Thanks for any help I can't get yall. Have a great day.

Anyone know of an off-the-shelf device that would give an audible signal when there is a short in the track power?  I have circuit breakers that trip to protect the power supply but sometimes the first hint I have of a problem is the overheating of the ICs on the board.  At one of my op sessions an engine got derailed and before I realized the problem the circuit breaker was cooked.

I use Rail Lynx and the track voltage is regulated at a constant 12.5 DC.
