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.

An insulated embedded track construction for a transit railway comprising: first and second spaced, generally parallel rails extending for an indefinite length in a first longitudinal direction; plural, spaced ties disposed generally perpendicular to the rails in supporting relation thereof; plural rail clips secured to said ties and engaging said rails at spaced positions along said first direction for fastening said rails to said ties; and, a first composite insert disposed in abutting engagement with said first rail, said first insert extending continuously along said indefinite length in said first longitudinal direction, said composite insert including a first, generally rigid channel having first and second legs extending outwardly from a connecting portion and defining a cavity for receiving said rail clips, and an elastomeric member cooperating therewith.
