Last Updated:February 27, 2026, 08:00 IST To ensure the safety of these faster journeys, the Railway Board has approved a proposal to double the distance between signals from the current 1 km to 2 km At speeds exceeding 130 kmph, the “sighting distance” of a signal becomes dangerously short. This is worsened by external factors such as heavy rain, sharp curves, or the thick fog common in North India.

This will be reflected in how the railways manages its traffic: a move towards fewer trackside signals and a significant increase in the distance between them, as well as thorough Kavach implementation. HOW DO FEWER SIGNALS HELP INCREASE SPEED? According to a report published by the Times of India, to ensure the safety of these faster journeys, the Railway Board has approved a proposal to double the distance between signals from the current 1 km to 2 km.
