ABSTRACT:
A modular railway crossing structure supports a pair of rails. The modular railway crossing includes multiple base members, which are aligned axially along the length of the rails. The rails are encased by rubber boot elements. Each base member has a central recess formed in the upper surface. A pair of planar central rail locking members fit in the recess. The base members and the central rail locking members interrelate to support the rails.
