Bengaluru Metro to become highly efficient with Alstom’s advanced CBTC signalling system

Bengaluru Metro will get a boost with Alstom’s automated Communications Based Train Control (CBTC) signalling system for the upcoming Phase -2 project. The latest technology development will significantly reduce travel time, traffic congestion, and CO2 emissions for the Bengaluru transportation system.

More Details:

Alstom, a global leader in smart and sustainable mobility, has been awarded the contract to design, manufacture, supply, install, test, and commission fully automated Communications Based Train Control (CBTC) signalling system for the upcoming Bengaluru Metro Phase 2, Reach 6, 2A and 2B. The contract worth 96.2 million euros with Bengaluru Metro Rail Corporation (BMRCL), includes training of personnel and annual maintenance for 5 years.

Linking Major Corridors:

  • This project aims to cater to the three major corridors of the Bengaluru metropolitan region, by linking the critical junction at Silk Board on the Outer Ring Road (2A) to the Kempegowda International Airport (2B) via KR Puram.
  • Reach-6 will connect Bannerghatta Road to Nagavara with interchanges at MG Road (Purple Line which connects to Whitefield); and yellow line at Jayadeva Hospital & the Blue Line at Nagavara.

Highlights of the Solutions to be Delivered to Bengaluru Metro Phase 2 – Reach 6, 2A & 2B:

  • At the core is Alstom’s world leading CBTC technology, enabling driverless operation offering an exceptional level of service across the combined line length of 80.39 kms, this project is expected to alleviate traffic congestion in the city by minimising travel time by at least 50%, reducing CO2 emissions, and making a substantial contribution to the expanding public infrastructure of India’s Silicon Valley.
  • Alstom’s rail cyber security solution, backed by a secure and certified development process, will deliver an efficient answer to emerging cyber threats by safeguarding the backbone of modern transportation.
  • To enhance passenger safety, full height platform screen doors (PSDs) will be installed at all underground stations on Reach-6 corridor and the Airport line terminal, and half-height platform screen gates (PSGs) will be installed at one at-grade station (2B corridor).
  • PSDs at underground stations can lead to significant energy savings by reducing air-conditioning needs. This will be the first implementation of platform screen doors on Bengaluru Metro corridors.

Alstom is a strong leader in the mass transit market and stands as the undisputed leader in CBTC technology worldwide. The company has over 30 years of expertise in radio CBTC and has been chosen for 190 CBTC metro lines, with over 90 lines in operation, worldwide. In India, 18 metro lines are currently equipped or underway, with Alstom’s world-class signalling solutions.

MD Stated:

Commenting on the occasion, Mr. Olivier Loison, Managing Director- Alstom India said, “Alstom is pleased to continue its longstanding partnership with Bengaluru Metro, which is India’s second largest rapid transit system. The expansion of the network is a boon for commuters as it provides fast, reliable, safe, and comfortable transportation while easing traffic congestion across the city. We are committed to providing world-class efficient and sustainable mass transport system that caters to the special needs of Bengaluru and support the transition towards a sustainable future.’’

What is Urbalis:

  • Alstom’s CBTC Urbalis™, a solution developed in Bangalore site with 1,000+ engineers for deployment of various solutions worldwide, will also offer the highest Grade of Automation (GoA4), which is commonly known as the ‘driverless technology’ across 50 stations and 3 depots.
  • Alstom’s Urbalis Vision™ platform will be setup at the integrated Operation Control Centre (OCC), being built at Baiyappanahalli, and the backup Control Centre (BCC) located at Peenya, which will serve as a command centre to control and monitor all train operations.
  • The onboard automatic train control will interface with the rolling stock manufactured by BEML, under Package 5RS-DM managing the headway and safety of 53 trains in a 6-car configuration each.

What is Health Hub:

  • Alstom will deploy its predictive maintenance tool – HealthHub, to enable real-time condition-based monitoring of the health of trains, infrastructure and signalling assets using advanced data analytics to predict the remaining useful life.
  • This approach minimises operational downtime, maximises system availability, and optimises lifecycle costs.

Alstom and BMRCL:

  • This is the third contract for Alstom with BMRCL. The company is currently providing traction and power supply electrification for the 33-kilometre extension to Bangalore Metro under Phase 2.
  • In 2009, Alstom won the contract to provide the U200 signalling and telecommunications solution for 42 kilometres of track comprising Bangalore Metro Phase I, which was completed in 2017.


The development marks a significant moment for the Bengaluru Metro as Alstom’s state-of-the-art technology will revolutionise its efficiency in terms of speed, safety, convenience and sustainability. The advanced CBTC system is expected to redefine the travel experience and make Metro travel much more attractive for the passengers.
