Colour Light Signals:
Due to the following advantages, Colour Light Signals are used instead of Semaphore Signals.
- In Colour Light Signals both day and night aspects are the same – avoids confusion to drives
- Signals have the longer range of visibility –, especially during the night.
- No Mechanical Moving parts – Easy to maintain.
- Not limited due to range of operation, as in mechanical signals
- Improved reliability of signals
- Improves punctuality.
