Delhi-Gurugram-SNB-Alwar RRTS: Project Profile

The Delhi-Gurugram-SNB-Alwar Regional Rapid Transit System (RRTS) is a high-speed, high-frequency commuter rail line under development to connect Delhi with key urban and industrial hubs in Haryana and Rajasthan. This project, a cornerstone of the National Capital Region’s Integrated Transport Plan, aims to drastically reduce travel time and foster polycentric development across the region. It is engineered to provide a safe, reliable, and sustainable mobility solution to mitigate congestion on National Highway 48 (NH-48).

Technical Specifications

The Delhi-Alwar RRTS corridor is engineered as a state-of-the-art semi-high-speed rail line. The infrastructure is being built on a broad gauge (1,676mm) double-track alignment, featuring both elevated viaducts and underground tunnel sections, particularly in the dense urban areas of Delhi and Gurugram. The system is powered by a 25kV AC single-phase 50Hz overhead catenary system, designed for high-speed operations.

Signaling and train control are managed through an advanced European Train Control System (ETCS) Level 2, overlaid with a Continuous Automatic Train Control (CATC) system. This integration includes Automatic Train Protection (ATP), Automatic Train Operation (ATO), and Automatic Train Supervision (ATS) to ensure high frequency (5-10 minute intervals) and safety. Communications rely on a Terrestrial Trunked Radio (TETRA) system and an optical fiber cable (OFC) backbone. The rolling stock comprises modern, lightweight stainless steel coaches with aerodynamic profiles, designed for ergonomic comfort and energy efficiency. These air-conditioned trains will feature premium and standard class seating, Wi-Fi connectivity, and dynamic passenger information systems.

Key Takeaways

• Economic Multiplier: The corridor is designed to unlock economic potential by connecting industrial zones like Manesar, Bawal, and Neemrana with Delhi’s economic hub, promoting balanced regional development.
• Decongestion & Modal Shift: It is projected to shift a significant volume of passenger traffic from road to rail, reducing vehicular congestion on the heavily trafficked NH-48 and contributing to a substantial reduction in carbon emissions and air pollution in the NCR.
• Intermodal Integration: The project emphasizes seamless connectivity, with RRTS stations planned to integrate with Delhi Metro stations, bus terminals, and other transport hubs, creating a unified and efficient regional transport network.

Frequently Asked Questions (FAQ)

When will the Delhi-Alwar RRTS open?

The project is being constructed in phases. The first phase, a 107 km stretch from Sarai Kale Khan in Delhi to SNB (Shahjahanpur-Neemrana-Behror Urban Complex), is currently under construction and is targeted for commissioning by 2028. The subsequent phase will extend the line from SNB to Alwar, with final completion dates subject to official updates from the National Capital Region Transport Corporation (NCRTC).

Who is building the Delhi-Alwar RRTS?

The National Capital Region Transport Corporation (NCRTC), a joint venture company of the Government of India and the states of Delhi, Haryana, Rajasthan, and Uttar Pradesh, is the nodal agency responsible for the entire project lifecycle. NCRTC has awarded design and construction contracts for various sections and systems to leading engineering and infrastructure firms, including Larsen & Toubro (L&T).
