I'd like to add Bluetooth train control to a static Emma Nevada train display.  The coal cars and the two accompanying passenger cars will rest on the track.  The engine will rest on jacks and not contact the rails.  Therefore the motor will only have slight current draw.  I believe that the motor stall current is not a factor.  The blue tooth unit I've been looking at has a maximum voltage of 24 Volts DC and a maximum current of 2 Amps. 

I'm considering the Bachmann 5 Amp power booster as the power source for my track.  The booster appears to have two voltage choices, 14 Volts and I can't read the second.  I don't understand the match on the amperage requirements.  Since the Bachmann booster is 5 Amps does that mean it's too hot for a 2 Amp Bluetooth decoder?

The 5 amps refers to the maximum current the unit can deliver. The motor will determine how much current it needs. Running light as you describe, it will not even come close to 2 amps, let alone 5.

Thanks Kevin!  I thought that was the way it worked but I wasn't sure.
