Abstract
A railway crossing, sometimes referred to as a diamond crossing, has four substantially identical crossing beams which have cutouts made for a wide range of crossing angles. At least two separate base plates are cut to fit the required crossing angle and positioned beneath the crossing beams. Each crossing beam has a flangeway groove extending along at least a portion of the beam length and each beam has integral rail shaped ends for connection to a standard rail section. The crossing beams have top cutouts and bottom cutouts that intersect and are set for a predetermined crossing angle. Boltless locator pins prevent horizontal movement of the top and bottom beams on the plates, and elastic fasteners hold the top and bottom beams to the plates to restrict vertical movement between the top and bottom beams and the plates.
