What two lights can be utilized for dead end sidings?

The utilization of a small red light or a combination of a top white light and a bottom red light for dead end sidings is correct because these signaling methods communicate specific messages to train operators regarding track conditions and safety.

In railway operations, a red light typically indicates danger or a stop signal, which is crucial in dead end sidings where a train may be at risk of inadvertently colliding with an obstruction or another train that is stationary. The addition of a white light may serve to designate the presence of a safe area or alert operators to specific instructions, enhancing visibility and the safety of operations in these locations.

This approach ensures that trains are clearly informed when approaching dead end sidings, allowing them to make informed decisions about speed and adherence to safety protocols. The use of these light configurations aligns with established signaling standards necessary for maintaining safety within railway systems.
