Progress Rail Services produces a line of grade crossing and wayside
signaling structures featuring such innovations as internal light
mounting on wayside structures of the Lincoln Industries design, which
contain the maintainer inside of the structure at all times. The company
says its patented sliding safety ladder has revolutionized the
gate-cantilever combo to allow the maintainer to safely climb over the
gate mechanism while not climbing “through” it. The slide ladder
assembly can also be used on standard grade crossing cantilevers and
wayside signal structures to keep the ladder up and out of reach.
