Скачать или смотреть Making an EOT Device

Wherein I install an EOT circuit in a boxcar. First used in 1969 by the Florida East Coast Railway, the End of Train Device (alternately referred to as an "ETD," an "EOT" or a "FRED" has replaced the caboose on modern trains. In this video, I show you how I made one in an N scale boxcar which can be activated and deactivated without picking up the car.
