HO GAUGE for use on OO / HO Gauge track. This brass locomotive is working, but needs one of the driver links to be screwed back onto the drive mechanism at one end. It is the size of a HOe or Hom locomotive, but designed to run on standard HO track. With a little fine reassembly you will be away. A great item for your collection. See pictures for details. But this depends on box size finally used, item sizes and weight.
