Noida Metro Rail Project: A Technical Profile of the Aqua Line Expansion

The Noida Metro Rail Project (NMRP) is a critical mass rapid transit system enhancing urban mobility between the high-density economic zones of Noida and Greater Noida in Uttar Pradesh, India. This project profile outlines the technical specifications, operational status, and strategic importance of its primary corridor, the Aqua Line, including its ongoing Phase 2 expansion. It focuses on the integration of advanced signaling, rolling stock, and sustainable infrastructure to establish a modern, efficient transit network.

Technical Specifications

The core of the NMRP is the Aqua Line, a 29.7 km elevated corridor with 21 stations connecting Noida’s Sector-51 to the Delta Depot in Greater Noida. The line is engineered for high-frequency service, powered by a 25kV AC overhead catenary system. A key technical feature is the implementation of Hitachi’s Communication-Based Train Control (CBTC) signaling, which enables precise train tracking, higher service frequency, and enhanced safety protocols. This system optimizes headways and supports the operation of ‘fast trains’ that skip select stations during peak hours to reduce travel time.

The rolling stock, supplied by CRRC Nanjing Puzhen, consists of lightweight, high-capacity trainsets designed for a maximum passenger load of 1,034. Station infrastructure is standardized with Platform Screen Doors (PSDs) to ensure passenger safety and improve climate control efficiency. The ongoing Phase 2 expansion will extend the Aqua Line by 14.95 km from Sector 51 to Knowledge Park 5, adding nine new stations and further integrating the Greater Noida West region into the rapid transit network.

Key Takeaways

• Strategic Regional Connectivity: The project successfully bridges the transportation gap between the residential and industrial hubs of Noida and Greater Noida, while its interchange with the Delhi Metro’s Blue Line integrates it into the wider National Capital Region (NCR) transit grid.
• Model for Project Execution: NMRP’s success is a blueprint for financing and development, utilizing a collaborative funding model (20% Central Govt., 20% State Govt., 60% loans) and leveraging the proven expertise of DMRC as a turnkey consultant.
• Advanced Technology Adoption: The deployment of modern technologies like CBTC signaling and PSDs sets a high benchmark for operational efficiency, safety, and passenger experience in India’s next-generation metro systems.

Frequently Asked Questions (FAQ)

When will the Noida Metro Phase 2 extension open?
The Noida Metro Aqua Line Phase 2 extension, which will connect Sector 51 to Knowledge Park 5, is currently under construction. Based on typical project timelines, it is projected to become operational in stages, with an estimated completion by late 2026 or early 2027, subject to official announcements.

Who is building the Noida Metro?
The Noida Metro project is being executed by the Noida Metro Rail Corporation (NMRC). The Delhi Metro Rail Corporation (DMRC) served as the primary turnkey consultant for the construction of Phase 1. Key technology and equipment suppliers include CRRC for the trains and Hitachi for the advanced signaling system.
