MRTS merger: Full takeover by CMRL likely after August 2027, says CUMTA

CHENNAI: The much-anticipated merger of the Mass Rapid Transit System (MRTS) with Chennai Metro Rail Limited (CMRL) has entered a critical phase, with the Railway Board granting in-principle approval for the transfer of assets, operations, and maintenance responsibilities to the State government.

The Chennai Unified Metropolitan Transport Authority (CUMTA) is leading the transition process and expects to finalise the detailed MoU within the next two months.

CUMTA member secretary I Jayakumar told DT Next that a special committee comprising officials from Southern Railway and the State government was working on the MoU, which will “cover various aspects, including transfer of assets, valuation, and handing over of terminal stations. We’re looking to complete the formalities in 1-2 months”.

The CMRL has also been asked to prepare a Detailed Project Report (DPR) for MRTS station modernisation and another one for land development opportunities along the corridor. “The actual transfer process will take up to 24 months after the MoU is signed. SR will operate the MRTS in the interim. We anticipate CMRL will take over operations sometime after August 2027,” he added.

However, the transition is not without challenges. Procuring new rakes is expected to take at least 18 months post-tender, and significant signalling and station improvements are also required. “We’ve recommended a combination of AC and non-AC coaches to reflect the fare sensitivity of MRTS passengers. However, there is currently no supplier offering mixed configurations. So if this isn’t feasible, we’ll have to opt for either fully AC,” Jayakumar clarified.

The merger, first proposed years ago, was delayed due to infrastructure constraints, particularly the pending construction of a fourth line between Chennai Beach and Egmore. With that project now commissioned in March 2025, the path has been cleared for the formal takeover. In its approval note dated July 31, the Railway Board said the special committee had already prepared a broad framework and guiding principles for the MoU.

Responding to a question raised by DMK Parliamentary party leader Kanimozhi Karunanidhi on MRTS merger, Railway Minister Ashwini Vaishnaw said that the merger was a complex process involving issues of train operation, maintenance of assets and safety and the timeline cannot be stated at this stage. “Handing over of MRTS to GoTN is likely to bring better synergy amongst various modes of transport in Chennai, which will benefit commuters through this integration,” he said.
