Bachmann HO Christmas retail train

Product Name: Bachmann HO Christmas retail train
This is a EMD FT Diesel, box car and caboose from a set called North Pole and Southern Express. There is one car missing which is a 4 hopper coal car that's silver. I've tried to find one with no success. (Maybe sub a silver Southern gondola with tiny presents or small Christmas trees) I'm out of those as well. I completely disassembled the engine and cleaned all the drives. Cleaned the current retail pickups and installed a new headlight and hitches. Works fantastic. Also new hitches on cars.
