ABSTRACT:
A variable wheel-spacing truck is equipped with axle boxes slidably mounted on axles extending between side beams of a bogie frame. Axle box receivers are selectively and releasably connected with the axle boxes at a plurality of predetermined positions by locking members. When the truck is moved from a first railway to a junction railway, auxiliary wheels mounted on the axle box receivers engage with running paths and raise the truck and a vehicle body except the wheel sets and release a locked condition by the locking members. When the truck is moved through a region where the track gauge of the junction railway is changing or where the spacings of inside or outside guide rails is changing, the wheels are pushed by a pair of guide rails or a pair of junction railway rails and shifted transversely together with the axle boxes relative to the axle.
