What is the purpose of a 'flagman' at railway crossings?

The role of a flagman at railway crossings is integral to ensuring safety in areas where vehicle traffic crosses train tracks. Their primary duty is to control traffic and facilitate safe passage across the tracks, especially during times when trains are approaching or when there are ongoing railway operations. By signaling to oncoming vehicles and pedestrians, a flagman helps to prevent accidents that could occur if someone attempts to cross the track when it is unsafe to do so. Their presence is crucial in minimizing the risk of collisions and ensuring a smooth flow of both train and vehicle traffic at crossings. This duty is essential for maintaining safety in environments where rail and road traffic intersect, making the function of a flagman indispensable in railway operations.
