A three axle truck for locomotives needing 3 wheel set motors. The motors have a third wheel set hinged to the motor body using 2x3 plates with hole and a technic pin. The stacked 2x3 plates with hole give the attached wheel set mass and keeps the link between the wheel set and the motor solid so as to maintain the illusion that it is a solid unit.
A view of both trucks. The hinge method keeps the illusion that its a solid unit and the details on the 3rd wheel set closely mirror the decorative sides of the motors
