Bangalore (Metro Rail News): Bangalore Metro Phase 2 achieved another milestone as CRRC supplied the prototype train for the Purple Line at Green Line’s Peenya Depot.
With this development, BMRCL has received both prototype trains for the Yellow and Purple/Green lines of Bangalore Metro Phase 2.

As per the Titagarh Press Release, “Titagarh will deliver two more trainsets to the Yellow Line by April this year. The company will then ramp up production, delivering two trains a month by September 2025“. Titagarh, with support from CRRC’s engineers, will handle the assembly of all trains from this contract.
Train Specification
This 6-coach train set delivered by CRRC is part of Phase 2’s rolling stock 4RS-DM which was initially awarded to Chinese rolling stock manufacturer CRRC by Bangalore Metro Rail Corporation Ltd (BMRCL). This train for Purple Line has been equipped with a DTG (Distance to Go) signalling system. CRRC rolled out this prototype from its Nanjing Plant in December 2024.
However, the trainsets for the Yellow Line are equipped with communications-based train control (CBTC) signalling systems and are capable of running in GOA4 mode.
