What are Gap Stations used for in train operations?

Gap Stations are crucial in train operations primarily for their role in managing train movements and ensuring efficient scheduling. These locations are strategically chosen to monitor the passage of trains, helping maintain the correct spacing between them. This functionality supports optimizing connections between various train lines, facilitating smoother transitions and transfers for passengers. By accurately recording the timings and movements of trains as they pass by these stations, operators can effectively coordinate their schedules, making sure that trains are properly spaced and reducing the potential for delays. This aspect is vital for maintaining the overall efficiency of the rail system and minimizing disruptions in service.

The other roles mentioned in the other choices, such as maintenance locations or storage areas, do not align with the primary purpose of Gap Stations within the operational context of train management.
