What is the purpose of a temporary block limit?

The purpose of a temporary block limit is to control train operations through specific areas. This is particularly important in situations where there may be work being done on the tracks, such as maintenance or repair activities. By establishing a temporary block limit, the railroad can ensure that trains are restricted from entering or passing through certain sections of track, thus maintaining safety for both workers and train operations.

This control mechanism allows for the effective management of train movements, ensuring that trains stop before reaching a work zone or are instructed to slow down, thereby preventing potential accidents. It's crucial in a safe and efficient railway system, as it keeps operations organized around areas requiring special attention or caution.
