1) Red signal
2) Green signal
3) Yellow signal
4) Blue signal

Answer 1

The clear signal in subway sections indicating it is safe for the train to proceed is a green signal. This system is in line with standard traffic light color-coding and manages rail traffic effectively.

Step-by-step explanation:

In subway systems, the signal indicating it is safe for the train to proceed is typically a green signal. This follows the standard color-coding of traffic signals where red means stop, green means go, and yellow indicates caution.

However, in the context of subway or train operations, this signal system is more complex, involving additional signals and meanings for managing rail traffic. The clear signal facilitates the smooth and safe operation of trains, helping to prevent collisions and allowing for efficient scheduling and movement of subway trains.
