Retractable Railroad Derails

A derail or derailer is a device used to prevent fouling, blocking, or compromising of a rail track or collision with anything present on the track such as a person, or a train, by unauthorized movements of trains or unattended rolling stock. The device works by lifting the flanges of the wheels and dropping them clear of the rails.

More convenient than a hinged derail, the retractable derail shoe slides in and out of the housing through the leverage of a waist-high operating lever. No need to bend or stoop to activate or deactivate the derail, conveniently work from a comfortable standing position alongside the track. Our retractable derails are for use with freight cars and locomotives. Models include one-way left throw, one-way right throw, and two-way options.
