BTW, I haven't ever stalled a MTH diesel or steamer. My MTH 2 rail doesn't have traction tires. I do run their 3 rail and also there G scale with traction tires.
How many volts is the power supply?
I DO have smoke turned off on this loco.
Voltage is 13 volts, determined by power supply (I added this to original post).
