초록

An insulation system for an embedded track construction for a transit railway having spaced parallel railway rails includes a rail boot for substantially enclosing each of the rails along its length, rail clips extending on each side of each of the rails for securing the rails to supporting ties, and fillers extending on each side of each of the rails, frictionally engaging and removably mounting the rails to an associated one of said rail clips. The fillers cooperate to provide a coplanar roadway with said rails.
