<p>A bogie (120) and a convertible roadway-railway trailer (160) for both roadway and railway use and a method of converting the trailer between roadway and railway mode, including a method of assembling and disassembling a plurality of such trailers (160) and bogies (120) into a train (113). A trailer (160) has retractable roadway tires (166) and three king pins (184, 185) mounted on the posterior end thereof forming a rigid coupling mechanism. A bogie (120), which is stored off a railway near a grade crossing, has three king pin engagement mechanisms (138, 153) which are used to rigidly couple the bogie (120) to a trailer (160). To convert a first trailer (160) from roadway use to railway use, a tractor (112) is used to back up the first trailer (160) to a first bogie (120), and the first trailer (160) is rigidly coupled to the first bogie (120). Additional trailers (160) can be added in a similar manner to form a train (113). <IMAGE></p> |
