I have these Marx train items restored to operation. The loco has old rough paint but the motor and E-unit work fine after cleaning and servicing. The side rods are replacements from something else, they fit OK. The cars needed rusty wheels and axles cleaned up, and I had to replace some missing wheels and couplers. These metal Marx cars have a lot of drag but the loco is fairly powerful. The die-cast tender is unusually heavy. The drivers are a bit short for a Pacific-type, but it's pretty deluxe for an old Marx!
