Regional Rapid Transit System (RRTS) project:

• RRTS is a rail-based regional transit system being developed to connect various cities in India's National Capital Region (NCR) for faster and more efficient mobility. 
• The project aims to build high-speed rail corridors connecting Delhi with Meerut, Panipat, Alwar, and other major NCR cities. The corridors will have a design speed of 180 kmph and an operating speed of 160 kmph.
• RRTS is being implemented by the National Capital Region Transport Corporation (NCRTC), a joint venture of the Government of India and states of Delhi, Haryana, Rajasthan and Uttar Pradesh.
• The first RRTS corridor being constructed is the 82 km Delhi-Meerut corridor. It will have 24 stations and is expected to reduce travel time between Delhi and Meerut to around 60 minutes from the current 3-4 hours by road. 
• The corridors will be constructed on a fast-track basis using precast segment technology for timely completion. The Delhi-Meerut RRTS is scheduled to commence operations in 2023.
• RRTS trains will have business class and economy class coaches. The system is designed for a peak hour capacity of 40,000 passengers per hour per direction.
• Advanced systems like communications-based train control (CBTC), platform screen doors, baggage X-ray scanners, etc. will be implemented on the RRTS network. 
• The estimated cost of the Delhi-Meerut RRTS corridor is around Rs 30,000 crores. The entire RRTS network covering Delhi NCR is expected to cost over Rs 1 lakh crore.

Key details about Regional Rapid Transit System (RRTS) project:

• Rolling stock: The trains will consist of 6 cars with a total length of 72 meters and width of 3.2 meters. The maximum operating speed will be 160 kmph. The trains are being supplied by Bombardier Transportation.
• Traction and power supply: The RRTS corridors will be electrified with a 25kV AC overhead catenary system. Power requirements are estimated at about 50 MW. Substations will be built along the routes to feed power.
• Signaling system: The RRTS network will have the latest Communication Based Train Control (CBTC) system provided by Thales Group. This will help manage train movements efficiently and allow higher frequency operations.
• Track system: RRTS uses standard gauge tracks suitable for high speeds. Special heat-resistant rails, concrete sleepers and elastic fastening system will be used to withstand high temperatures and speeds. 
• Safety and security: Safety features like platform screen doors, fire & smoke detection systems, emergency braking system will be implemented. CCTV surveillance, baggage screening systems will be deployed for security.
• Integration with other transport modes: RRTS stations will provide smooth intermodal integration with metro trains, buses, taxis, private vehicles for last mile connectivity. Parking lots are also being built.
• Economic impact: RRTS is expected to reduce traffic congestion and drive economic growth in NCR. Significant savings in travel time costs are projected. Tourism, real estate, commercial activity will also be boosted.
• Future expansion: In the second phase, four additional RRTS corridors linking Delhi with Panipat, Sonepat, Gurugram, Rewari, and other cities are planned. The total network span will be around 800 km.
