Step-by-step explanation:
In a track work gang, the person responsible for the proper display of signals is the signalman. The signalman's role is vital to ensuring the safe and efficient movement of trains on the tracks. They use various signaling devices such as flags, hand signals, and mechanical or electronic signals to communicate information to train operators.
For example, a red signal indicates the train must come to a complete stop, while a green signal means it is safe to proceed. The signalman must be knowledgeable about the different signals and their meanings to maintain proper communication and avoid accidents on the railroad.
Signalmen play a critical role in maintaining the safety and smooth operation of railways, especially during track maintenance and repair work. Their responsibilities may also include coordinating with train dispatchers and other personnel involved in the track work to ensure seamless operations.
