ABSTRACT OF THE DISCLOSURE A motorized unit for driving a train on rails, in which the train is made up of a plurality of standard convertible rail-highway semi-trailers carried by rail bogies and hooked thereto through a fifth-wheel means including a coupling king pin. The motorized unit comprises a power semi-trailer of a convertible rail-highway type, having a coupling king pin arrangement at one end for connection with a rail bogie of one of the standard semi- trailers. It also has a rear bogie solid with the other end of the power semi-trailer and provided with a pair of railroad driving wheels operatively connected to this power semi-trailer to be driven thereby. The rear bogie has an upper surface that projects rearwardly of the power semi- trailer and is provided with a fifth wheel which is sized and positioned to receive and interlock with a coupling king pin of one of the standard semi-trailers to be driven. The rear bogie is further provided with a pair of retractable road wheels. Advantageously, the railroad driving wheels are actuated by electric motors fed by an electric generator operated by a diesel engine. These electric motors, generator and diesel engine are contained in the power semi- trailer.
