???To Jim Banner and others that offered help whenI asked about dc burning up dcc units,I now have a runaway machine.Now,instead of being dead on the tracks,it's a runaway!!!Before I could try to reprogram on the EZ command module,it started to run at full peed and at any and all 10 positions.Only way to stop it is to hit the stop button.
This is getting weird and humerous.Does this mean that the decoder logic is kaput and sending a signal to run,but why does the speed override the command module's rheostat?

Hi,I'm helping my 8yr old grandson repair his locomotives(commander set) and don't recall which type of coupler works best.Also,do you remove the entire housing on the loco or just fit a spring part back into it?

My grandson and I are new to model trains and could use some advice on replacing a broken coupler box for a bachmann Sant Fe GP-40(#3507)locomotive.
Do we need an exact replacement and where do we go to get one?I have browsed suppliers and am not sure what fits.
