ABSTRACT:
An improved standard crossing for railroad track is provided, having an interchangeable insert. The interchangeable insert permits easy changing of the most commonly worn pieces in situ, and avoids the expense of having to remove and replace the entire crossing when only parts of it are worn or broken. A filler member for fitting in to support and strengthen the crossing, as well as turnouts and other railroad structures, is also provided. The filler member makes it easy to align and assemble the structure, while also supporting the head portion of the rail.
