The correct answer is: Block Section.
A signal-controlled block section (SLB) is a section of railway track that is controlled by a railway signal. The SLB determines the limits of the station section and the block section. The station section is the area of track between two adjacent stations, while the block section is the area of track between two adjacent signals.
The SLB is used to control the movement of trains on the railway. The signal at the entrance to the SLB will only allow a train to enter the SLB if the track is clear. The signal at the exit from the SLB will only allow a train to leave the SLB if the track is clear and the next signal is in the clear.
The SLB is an important safety feature on the railway. It helps to prevent collisions between trains.
A. Block Section: A block section is a section of railway track that is controlled by a railway signal. The block section is the area of track between two adjacent signals. The signal at the entrance to the block section will only allow a train to enter the block section if the track is clear. The signal at the exit from the block section will only allow a train to leave the block section if the track is clear and the next signal is in the clear.
B. Station Section: The station section is the area of track between two adjacent stations. The station section is controlled by a railway signal. The signal at the entrance to the station section will only allow a train to enter the station section if the track is clear. The signal at the exit from the station section will only allow a train to leave the station section if the track is clear and the next signal is in the clear.
C. Station Limit: The station limit is the point at which a train enters or leaves a station. The station limit is marked by a railway signal. The signal at the entrance to the station will only allow a train to enter the station if the track is clear. The signal at the exit from the station will only allow a train to leave the station if the track is clear and the next signal is in the clear.
D. None of these: None of the options are correct. The correct answer is: Block Section.
