Abstract

An adjustable switch point guard includes a wear bar rigidly affixed to an adjustment plate. The adjustment plate is mounted on a fixed base plate which is attached to railroad ties. A threaded fastener on one of the adjustment plate or the base plate engages a first pair of bores in the other of the adjustment plate or the base plate to position the wear bar and adjustment plate 54 relative to a switch point and a fixed rail. Additional setes of bores are provided to enable the adjustment plate and wear bar to be moved relative to the base plate.
