No need to remove the trucks, just the wheels/axles/coupler plate to service the sliding shoes and clean/lube axles. Takes about 30 seconds to remove, 30 seconds to replace on each truck by gently spreading the truck bolsters(they're a soft spring steel) and reverse to replace.
The car is activated by any 5 rail remote control section - UCS / RCS / 1019 / 6019.
