Title
(EN) Method and Apparatus for Vehicle-Based Switch Locking in a Rail Network
Abstract
(EN)

A switch locking system and method of an authorized locomotive for safely traversing a switch in a railway including sending a lock command from a computer onboard the authorized locomotive to a switch controller associated with the switch; determining if a lock confirmation from the switch controller is received by the computer onboard the authorized locomotive; and safely traversing the switch upon receipt of the lock confirmation. The switch locking system and method may include sending an unlock command from a computer onboard the authorized locomotive to a switch controller after the train clears the switch.
