Abstract:

A railroad crossing panel filler for attachment to a headed support member on a railroad crossing panel slab includes an elongated elastomeric filler body with a slab engaging surface formed along the body. A rail engaging surface is also formed along the filler body opposite the slab engaging surface. An elongated support member head receiving channel is formed within the filler body and extends along the length thereof between the slab engaging surface and the rail engaging surface. An elongated support member receiving slot extending along the length of the filler body and includes a first open end along the slab engaging surface and a second end opening into the enlarged support member head receiving channel. The support member head receiving channel and support member receiving slot are configured to releasably receive a headed panel support member to releasably mount the elastomeric filler body to the panel.
