I have two LGB 0-4-0 Stainz locos that run at different speeds. One loco has a smoke unit and cab light in addition to the headlight and it is the slower of the two locos at the same voltage setting. The second loco has only a headlight and no smoke unit, and is the faster engine at the same voltage setting. I would like to doublehead these engines, since they have the same gearing. I am concerned the back EMF in the faster loco will be reduced, causing it to lose resistance and draw more current and possibly overheat. It will, in effect also be pushing the slower engine, possibly affecting its motor as well. I am guessing the answer is do NOT doublehead locos that run at different speeds at the same throttle setting, and risk damage to both motors. Appreciate some input here. THANKS in advance!
