Is there anyone or a company that can reliably re-motor Bachmann Spectrum steam loco's. Bachmann only replaces stuff if there is a current run. Oddly they do few repairs. I've tried. I have a J Class Northern that they have the motor for: 2, 2-6-6-2 Mallet's and 2 heavy mountains that they do not have motors for. I've ohm-ed out the motors and they are shorted. I can do a lot myself but will not tackle removing running gear. Let alone finding motors. Thanks.
