    摘要: A rail system for a vehicle in which a joint piece interconnects adjacent lengths of rail. Each joint piece is of similar cross section to the rails and is wedge shaped to co-operate with wedge shaped ends on the rails. Engagement means are provided within the cross-section of the rails which transmit at least part of the vehicle weight from the joint-piece to the rails, of which the following is a specification.
