Rail transport bogie (1 ) configured to operate on a track (2) having track surfaces (3,4) on opposite sides thereof and an slot (5) extending along substantially the centre of the track (2), the bogie (1 ) comprising a load-bearing wheel (9) to run on a first (3) of the two track surfaces, a support shaft (1 1 ) extending from the load-bearing wheel (9) operatively through the slot (5) in the track (2) and terminating in load support means (8), a first pinch wheel (12) rotatably secured in a forward position (20) in respect of the support shaft (1 1 ) and a second pinch wheel (13) rotatably secured in rearward position (21 ) in respect of the support shaft (1 1 ), with both the first (12) and second (13) pinch wheels located between the load-bearing wheel (9) and load support means (8) to run on the second (4) of the two track surfaces, the load-bearing wheel (9) and pinch wheels (12,13) clamping between them the bogie (1 ) to the opposing track surfaces (3,4), and at least one of the load-bearing wheel (9) and either or both of the pinch wheels (12,13) connected to a motor (10) operatively to be driven thereby to comprise a driven wheel for the bogie (1 ). Also disclosed are a rail transportation system and a track for a rail transportation system using such a bogie (1 ). |
