Bachmann B1 locomotive. Seems to run back and forth and has a 8 pin rails decoder fitted. The front boogie is missing the screw spring so that’s separate from the loco. It looks like someone has used a wood screw to try put the boogie back on so the screw hole may need an attention. Overall the loco seems and okay condition and comes boxed. Good project as I don’t think this would take much to put right. See photos as this forms part of the description. It’s not been properly tested so selling as spairs or repairs.
