Delhi Metro has launched new extensions on the Pink Line (Line 7) and Magenta Line (Line 8), boosting connectivity across the National Capital Region. Equipped with Alstom’s modern trainsets and advanced signalling technology, the lines promise smoother and more efficient travel. The project also moves Delhi closer to becoming one of the world’s largest and most advanced metro networks.

Introduction:

Delhi Metro has taken another major step towards improving urban mobility with the commencement of revenue service on the extended sections of Line 7 (Pink Line) and Line 8 (Magenta Line). The expansion is supported by advanced metro trains and signalling systems provided by global mobility solutions provider Alstom.

The new development is expected to enhance seamless connectivity across the National Capital Territory (NCT) while supporting sustainable urban transport for millions of daily commuters.

The extensions include the Majlis Park to Maujpur section on Line 7 and the Majlis Park to Deepali Chowk section on Line 8. These routes are strategically important as they strengthen the overall metro network by creating additional interchange points and improving travel options for commuters across Delhi.

Strengthening Delhi Metro’s Network Connectivity:

The new extensions will significantly improve passenger convenience by linking multiple metro corridors. In particular, the Line 8 extension provides interchange connectivity with three important lines in the Delhi Metro network.

These connections include:

With these new interchange options, passengers will experience smoother transfers and reduced travel times across the network.

The extensions also play a vital role in expanding the Delhi Metro’s reach to previously underserved areas, making public transportation more accessible for residents in different parts of the city.

Advanced Metro Technology from Alstom:

Alstom has supplied modern Metropolis metro trainsets for the Pink and Magenta Line extensions along with advanced signalling systems. These trainsets are designed to provide a comfortable and efficient commuting experience.

The trains are built with several advanced features including:

The trains have been fully manufactured in India at Alstom’s state-of-the-art facility located in Sricity, Andhra Pradesh, which is the company’s largest urban rolling stock manufacturing site in Asia.

India’s First Circular Metro Line:

With the completion of the new section, the Pink Line will achieve a significant milestone by becoming India’s first circular metro corridor. This development is expected to transform travel patterns across Delhi by allowing commuters to move around the city without needing to pass through central interchange stations.

The Pink Line will also become the longest metro line in India equipped with Unattended Train Operation (UTO) at the highest level of automation.

This advanced automation will allow the trains to operate with Grade of Automation 4 (GoA4) technology, enabling driverless train operations in the future.

Insight:

Mr. Olivier Loison, Managing Director, Alstom India said, “We are honoured and proud to be a long-standing partner of DMRC through its journey of becoming one of the world’s largest metro networks today. Together, we are committed to providing a safe, efficient, and environmentally friendly travel experience to commuters and the Magenta and Pink line extension will truly enhance DMRC’s neural metro network connectivity in the region”.

State-of-the-Art Signalling System:

The extension of Line 7 is supported by Alstom’s Urbalis Flo signalling system, which is based on Communications Based Train Control (CBTC) technology.

CBTC technology allows metro systems to operate more efficiently by improving train frequency and safety. Key advantages include:

The system is designed to support fully automated train operations in the future, making Delhi Metro one of the most technologically advanced metro networks in the world.

A Long-Standing Partnership with DMRC:

Alstom has maintained a long-standing partnership with the Delhi Metro Rail Corporation (DMRC). Over the years, the company has delivered more than 800 metro cars that are currently operating across the Delhi Metro network.

The company is also supplying 312 metro cars as part of Delhi Metro’s Phase IV expansion project under a contract valued at €312 million.

These trains are built with a strong focus on passenger comfort, reliability, and sustainability, aligning with Delhi Metro’s goal of providing efficient public transportation.

Maintenance and Future Collaboration:

Alstom recently strengthened its collaboration with DMRC by securing a 10-year maintenance contract for Lines 1 and 2.

The agreement includes comprehensive maintenance services such as:

This partnership ensures long-term operational efficiency and reliability across key metro lines.

Alstom’s Contribution to India’s Rail Infrastructure:

Beyond Delhi, Alstom has played a significant role in several metro projects across India. The company has supplied trains and rail solutions for cities including:

In addition, Alstom recently delivered trains and signalling systems for India’s first semi-high-speed regional rail network, the Delhi–Ghaziabad–Meerut RRTS corridor.
