In TALQ signalling system, ________ signal will be treated as defective if home signal becomes defective. A. Outer B. Call-On C. Hand D. Non eof these

Outer
Call-On
Hand
Non eof these

The correct answer is: Outer

A TALQ signalling system is a type of railway signalling system that uses a combination of track circuits and colour light signals to control train movements. The system is designed to provide a high level of safety and efficiency, and is used in many countries around the world.

In a TALQ signalling system, each track circuit is associated with a specific signal. If the track circuit detects a train, the signal will be displayed as “red” (stop). If the track circuit is clear, the signal will be displayed as “green” (proceed).

The “outer” signal is the signal that is located at the entrance to a section of track. If the home signal becomes defective, the outer signal will be treated as defective. This means that trains will not be able to enter the section of track until the home signal is repaired.

The “call-on” signal is the signal that is located at the exit of a section of track. If the home signal becomes defective, the call-on signal will not be affected. This means that trains will still be able to exit the section of track, even though the home signal is red.

The “hand” signal is a manual signal that is used to control train movements in the event of a failure of the automatic signalling system. The hand signal is usually located at a point where there is no automatic signalling, such as at a level crossing.

In conclusion, the correct answer to the question “In TALQ signalling system, __ signal will be treated as defective if home signal becomes defective” is “Outer”.
