The RRTS is envisioned as a semi-high-speed (160–200 kmph), rail-based system that can carry large passenger volumes over inter-city distances in 30-60-minute trip times, much faster than road travel.
What is RRTS?
RRTS is planned to decongest the city by allowing faster reach to city centre from sub-urban areas. Currently, only 55-km section of the Namo Bharat Corridor between New Ashok Nagar in Delhi to Meerut South Station is operational for commuters. The stretch is a part of Delhi-Ghaziabad-Meerut RRTS corridor.

The CMRL has launched three simultaneous feasibility studies to define RRTS networks that will link Cities of Chennai and Coimbatore with their neighbouring regional centres. In a statement, the CMRL said, “…appointed M/s Balaji Railroad Systems Private Limited as the Feasibility-Study Consultant for the three assignments.”
According to CMRL, the consultants will study alternate options of route for each planned RRTS lines, choosing station points, depot and smooth change-over points with other transport modes.
“This assignment will decide whether tracks should run on-ground, raised, or underground, land needs, environmental issues and broad project cost,” it said in a statement on August 1.
