Abstract
A rail system includes a main track, a spur track connected to the main track by a switch changeable between a closed state and an open state, and a station spaced from the main track and accessible by the spur track. The rail system further includes a train with a passenger car and an EMDI releasably coupleable behind the passenger car. A method of operating the rail system includes decoupling the EMDI from the passenger car when the train is moving at a first speed toward the switch in the closed state. The EMDI is decelerated to a second speed less than the first speed. After the train has moved past the switch and the switch has been changed to the open state, the EMDI is diverted from the main track to the spur track via the switch in the open state and decelerated to a stop at the station.
