If a train has a horn failure on the lead locomotive, who must be notified immediately?

In the case of a horn failure on the lead locomotive, notifying the Train Dispatcher or Control Operator is crucial for maintaining overall safety and operational efficiency on the railway. The horn is an essential safety device used to communicate with other railway staff, warn of the train's approach, and alert pedestrians and vehicles at crossings.

By informing the Train Dispatcher or Control Operator immediately, they can take appropriate action, which may include monitoring the train more closely, advising other trains in the vicinity about the situation, or coordinating an alternative response to ensure safety. This person is responsible for overseeing train operations and can communicate vital information to other personnel involved in train movements.

Other choices would not be as effective in addressing the immediate safety concerns associated with a horn failure. The local police might be involved later if there are incidents or traffic concerns, while notifying the engineer alone would not ensure that the operational oversight necessary for safe train handling is maintained. Informing nearby trains is important, but the Train Dispatcher is the central figure who manages train movements and safety protocols for all trains in the area.
