What does the term "crossing gate" refer to?

The term "crossing gate" specifically refers to safety mechanisms designed to enhance the safety of both vehicle traffic and train operations at level crossings, where roads intersect with railway tracks. When a train approaches, these gates lower to block vehicle traffic, indicating that it is not safe to cross the tracks. This prevents collisions between vehicles and trains, contributing to a safer environment for both passengers and drivers. The function of crossing gates is crucial, as they provide a clear visual signal to motorists to stop when a train is nearing, thereby reducing the risk of accidents.

While signals that indicate the speed of the train pertain to train operation, they do not encompass crossing gates, which serve a different purpose. Similarly, warning signals at train stations do not involve the physical mechanism of a crossing gate, and forms of communication for train engineers focus on operational communication rather than physical barriers for roadway traffic.
