Mumbai and Pune metro rail have awarded signalling contracts worth about Rs. 700 crore (Euro 90 million) to major, Alstom.
The company will install Communication Based Train Control (CBTC) signalling under the contract. The signalling systems will be implemented on Mumbai Metro’s under construction Line 2A [Dahisar West – D N Nagar], Line 2B [DN Nagar – Mankhurd via BKC] and line 7 [Dahisar East –Andheri East] on the Mumbai metro.
On Pune metro, CBTC will be implemented on Line 1 [PCMC-Swargate] and line 2 [Vanaz-Ramwadi].
On the Mumbai metro, the signalling tender includes design, manufacture, supply, installation, testing and commissioning of CBTC. Also part of the package is supply and commissioning of equipment for 63 trains. Telecommunications includes public address systems, passenger information display systems, fibre optic transmission systems, CCTV, and access control systems.
On the Pune metro, the CBTC will run 31 trains on the 32-kilometre-long stretch, at higher frequencies, speeds and safety.
CBTC implementation is also on the anvil on Mumbai suburban railway as part of Mumbai Urban Transport Project (MUTP-3A).
CBTC allows a higher number of trains to be run within a block section using two-way communication between a train and the control room manning the track signalling system. It uses real-time information to control reception and dispatch of trains. This enables the handling of a higher number of trains in a block section thus improving line capacity utilisation.
