HOn30 Railbus
This is a picture of a free-lanced HOn30 railbus. A Bachman N-scale
trolley provides the motive power. In this case one end (truck) of the chassis
is cut off, leaving a rather elongated "spud"-type drive. This
is shoehorned into an HO scale Jordan Highway Miniatures 1934 Ford
bus. The front truck is a low-profile N-gauge archbar. There is room on
top of the motor to put seatbacks and the upper torsos of plastic figurines;
you can make out the seatbacks in the picture. The disk-shaped copper object
is a US penny (7.5 mm diameter).
