Contact rail jumpers are utilized in which situation?

Contact rail jumpers are specifically used in situations where a train or car becomes stalled in a contact rail gap. These jumpers serve a crucial purpose in maintaining electrical continuity along the contact rail, which is necessary for providing power to electric trains. When a vehicle becomes stalled in a gap, the contact rail jumper allows for the continuity of the electrical circuit, enabling other trains to pass or providing a means to relocate the stalled vehicle without losing power to the surrounding track sections.

This application highlights the importance of ensuring that electric trains can operate effectively, even in the event of a minor disruption. By bridging the gap temporarily, operators can manage the situation more safely and efficiently.
