Abstract
A railway baseplate assembly comprising a baseplate ( ), a cushioning pad ( ) for lying beneath the baseplate ( ), and means ( ) for securing the baseplate ( ) to an underlying rail foundation when the assembly is in use, wherein the said securing means ( ) comprise a non-screw-threaded post member ( ), which post member ( ) extends, when in use, through holes ( ) provided in the baseplate ( ) and cushioning pad ( ) in such a way as to engage the said baseplate ( ). The post member ( ) and baseplate ( ) may be such that engagement of the baseplate ( ) with the post member ( ) can be brought about by movement of the baseplate ( ) relative to the post member ( ) firstly in a direction substantially perpendicular to the plane of the baseplate ( ) and towards the post member ( ) so that the post member ( ) extends through the hole ( ) in the baseplate ( ) and secondly in a direction substantially parallel to the plane of the baseplate so that the post member ( ) engages the baseplate ( ). The post member ( ) is fastened, directly or indirectly, to the rail foundation and the post member ( ), cushioning pad ( ) and baseplate ( ) may be such that the cushioning pad ( ) and baseplate ( ) can be brought into engagement with the post member ( ) while the post member ( ) is fastened to the rail foundation.
