A railcar-moving vehicle comprises a modified semi-tractor, having a highway mode for operation on roadways, and a rail mode for operation on rails. The vehicle includes an elongate frame (12) with selectively extendable high rai l wheels (26, 28) for guiding the vehicle on rails (22), and rubber-tired driv e wheels (20) for operation on roadways. The rubber-tired drive wheels are configured to support the vehicle on a roadway in highway mode, and to conta ct the rails in rail mode. A moveable weight (44) is disposed on a rear portion of the frame. A load-shifting mechanism (46) moves the moveable weight betwe en a rearward position for rail mode and a forward position for highway mode.</ SDOAB> |
