EMBEDDED TRACK ASSEMBLY An embedded track construction for a transit railway including first and second parallel, spaced rails extending an indefinite length in a first longitudinal direction. A composite insert assembly extends along the indefinite length of the rails to electrically insulate the track rails from the surrounding ground surface. The composite insert also provides a positive water seal and allows lateral movement of the rail. The inserts include a first generally rigid channel and an elastomeric member received thereon. The rigid channel preferably defines an inverted, generally U-shaped configuration in which one leg is interposed between the top and bottom flanges of the rails. A second leg abuttingly engages conventional support ties that are perpendicularly disposed to the transit rails. Gauge side inserts include a cut-out formed in the elastomeric member to receive an associated wheel flange. The inserts facilitate crossing of the railway in a transverse direction, as well as travel in the longitudinal direction by emergency vehicles or the like. |
