What is the purpose of a watchman or lookout on the railroad?

The role of a watchman or lookout on the railroad is primarily to communicate warnings about train approaches. This is crucial for maintaining safety along the tracks, especially in areas where visibility may be limited or where there may be work or other hazards present. The watchman serves as an extra set of eyes, ensuring that any oncoming trains are spotted in time to alert workers or pedestrians, preventing potential accidents.

The duties of monitoring train speeds, repairing track damage, and managing crew schedules fall to other specialized roles within the railroad operations and do not align with the primary responsibility of a lookout. The lookout's focus is on vigilance and effective communication regarding train movements, which is vital in preventing accidents and ensuring the safety of everyone in proximity to the railway tracks.
