Why can't a red helmet be worn on the railway?
In the course of construction or maintenance work on the road, when the fault or defect that endangers the train is found, the train must be stopped manually until it is too late to notify the dispatcher or both stations. But if not stopped, the red hat can lead to misleading!
In the railway system, red stands for the parking signal and may be misleading when the locomotive crew is working on both sides of the line. It is considered to be a temporary stop signal, which can affect the driving! This kind of situation is very easy to happen under the condition of poor light and poor observation!
