|semantics =
A {{IS:Tag|derailer}} is a device used to prevent fouling of a rail track by unauthorized movements of trains or unattended rolling stock. It works (as the name suggests) by derailing the equipment as it rolls over or through the derail. {{external|https://en.wikipedia.org/wiki/Derail}}
