Question 3

What is a track circuit, and how does it work?
Answer:
A track circuit is an electrical circuit used to detect the presence of a train on a section of track. It works by sending a low-voltage current through the rails. When a train occupies the track, its wheels and axles short-circuit the current, which is detected by signaling equipment, indicating that the track is occupied.

Question 4

Explain the importance of automatic train protection (atp) systems.
Answer:
Atp systems are crucial for enhancing railway safety by automatically enforcing speed limits and preventing trains from passing signals at danger. These systems use onboard equipment to monitor train speed and location and can automatically apply the brakes if necessary to prevent accidents.

Question 5

What is communication-based train control (cbct)?
Answer:
Cbct is an advanced signaling system that uses continuous communication between trains and a central control system. This allows for more precise control of train movements, shorter headways, and increased capacity. It relies on wireless communication, onboard computers, and trackside equipment.
