signal failure
Transmission suddenly stops
Signal failure refers to the breakdown of a signaling system, especially in rail transport, where electronic or mechanical signals control train movement.
A signal failure can halt service across entire networks: Commuters faced delays due to a signal failure at Victoria.
The term extends to any breakdown in communication systems meant to convey information.
