What is a typical function of a 'home signal' in train operations?

A 'home signal' plays a crucial role in train operations, primarily serving to control and manage the movement of trains within a specific block section of the railway network. When a home signal displays a proceed indication, it signifies to the train engineer that a train is allowed to enter that particular block section, which typically means it is clear of any obstructions or other trains. This function is essential for maintaining safety and ensuring that train movements are coordinated efficiently.

By allowing trains to enter a block section, the home signal helps manage the flow of traffic on the railway, providing the necessary information to prevent collisions and maintain schedule adherence. In contrast, other functions such as displaying upcoming train schedules, informing engineers of necessary stops, or signaling the end of a line do not fall within the typical use of a home signal in the context of train operations.
