What is a "railway semaphore signal"?
A railway semaphore signal is a type of mechanical signal used to control train movements, typically consisting of a vertical arm that moves to different positions to convey instructions. The arm's position indicates whether a train should stop, proceed with caution, or continue at full speed. The arm is usually colored or marked to make it easier for train operators to understand the signal from a distance. Semaphore signals were widely used in the past, but have been largely replaced by modern electronic signals. However, they are still sometimes found in older railways or areas where older signaling systems are preserved.
Example
Engineers regularly inspect railway semaphore signals to ensure they are functioning correctly.
Railway semaphore signals are commonly seen alongside tracks, helping to control train traffic.
As the train approached the station, the railway semaphore signal changed, allowing the train to enter safely.
