In the late 1980s, the classic railroad caboose was largely displaced by the implementation of flashing "End of Train" or "EOT" devices, also known as "FREDs" or "ETDs." On prototype trains, the device autonomously monitors brake line pressure and is capable of sending train data to the locomotive, while also providing a blinking warning light to alert any following trains to the presence of the train in front. Our 50'6" Boxcar with operating flashing "End of Train" device allows you to replicate this essential modern component on your HO scale freight consists. Featuring a track-powered flashing red LED, the device can also be purchased on a standalone truck, allowing you to add this fun and authentic feature to compatible freight cars in your existing collection.
