Question

What are the signals that govern a series of consecutive blocks?

1) Block signals
2) Cab signals
3) Both block signals and cab signals
4) None of the above

Answer 1

Block signals and cab signals both govern a series of consecutive blocks in railway systems, ensuring the safety and efficiency of train operations by providing vital track status information.

Step-by-step explanation:

The signals that govern a series of consecutive blocks in railway systems are both block signals and cab signals. Block signals are visual devices located beside the tracks that inform a train engineer of track conditions ahead, such as whether the block is occupied or free. Meanwhile, cab signals are signal systems that provide similar information but are presented to the engineer inside the train cab, typically through a display or panel. Having both systems ensures that train operations remain safe by allowing consistent communication about track statuses, reducing the risk of collisions, and managing rail traffic effectively.
