Abstract
A rail fastener having provision for rail gauge adjustment comprises a pair of supports secured to the railway tie in a spaced relation on either side of the base of the rail and a spacer between each support and the rail base. A series of different width spacers are provided for exchangeable insertion between the rail base and support to allow lateral incremental shifting of the rail in the event that gauge adjustment is required. Resilient clips attached to the supports serve to hold down the rail between the spacers, and the dimensions of the spacers are also selected to provide constant deflection of the clips regardless of the adjusted position of the rail.
