Frequently Asked Questions

What Is a Retractable Derail?

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.

How are Retractable Derails Different from Hinged Derails?

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.
