INSULATING A PRECAST CONCRETE CROSSING WITH ELASTOMERIC RAIL ENCLOSURE

The industry is informed of a problem with signal circuit shunting in precast concrete grade crossings. A possible solution, electrical insulation of rail through grade crossings, is provided and a procedure for the electrical testing of grade crossings is suggested. The goal is not to recommend one type of grade crossing system over another or even to suggest that one grade crossing might be better suited over another type of grade crossing for one type of application. These decisions are best made by the engineering managers of each railroad or rail transit system. The goal is more to demonstrate how cooperation between the track engineers and the electrical engineers can provide positive results by using off-the-shelf components. The scope is to present information gained by experience in specifying, procuring, installing, and maintaining grade crossings on both light rail transit and freight tracks.
