KATO two axles drives
These 12V N gauge chassis come with factory installed coreless motor and flywheel. Also very popular with H0e/OO9 fans. They are superior replacements for the classic 11-103 and 11-104.
DCC operation possible, though you would have to open the model (clipped) and solder wires. Suitable decoders are available here.
A complete take-a-part can be found here, including DCC installation
