@PGentieu posted:Be careful about the uncouplers. From the uncoupling track owner's manual: "Be sure that your throttle is set to 10-12 volts (AC) to activate the magnet."
IIRC, the wall power supply that comes with the Polar Express (and other LionChief sets) provides 18VDC. So, unless you use a conventional AC transformer that you can adjust to within the 10-12 volt range, you cannot operate the uncoupler per the manual's specs.
Thanks for the heads up. I hope I didn't "cook" it already. I'll check it out tomorrow.
