Mumbai Metro: MMRDA Reopens Rs 4,298 Crore Global Rolling Stock Tender For Metro Line-4 And 4A

The Mumbai Metropolitan Region Development Authority (MMRDA) has reopened the bidding process for providing critical systems for Metro line-4 and line-4A — integral parts of the green line of Mumbai’s metro network.

This decision follows a two-year hiatus since Alstom Transport exited the project.

Initially shortlisted for bids in March 2021, Alstom anticipated delivery of the first set of equipment within 12 months. However, it declined by work delays and the unavailability of land for the depot.

The latest tender announcement for line-4 includes the supply of rolling stock consisting of 39 trains — each of six coaches — amounting to a total of 234 coaches.

The estimated cost of the contract is Rs 4,297.49 crore.

According to reports, Germany’s KfW will finance the design and build aspect of this contract, with a loan amounting to EUR 545 million, spread over a duration of 168 weeks. 

The metro lines-4 and 4A form part of the 57.18 km green line, which also includes lines-10 and 11.

This corridor will link Shivaji Chowk (Mira Road), Gaimukh, Kasarawadavali, Wadala, and Chhattrapati Shivaji Maharaj Terminus (CST) through a network of 48 stations.

The development of the Green Line began with line-4, a fully elevated corridor stretching 32.32 km from Wadala to Kasarvadavali, with 30 stations.

Extending the Green Line further north, line-4A will connect Kasarvadavali with Gaimukh, covering a distance of 2.88 km.

According to recent updates as of October 2023, Metro-4 has seen 58 per cent of its construction completed, while Metro 4-A has reached 61 per cent completion.

MMRDA anticipates that Phase 1 of the line, inclusive of 20 train-sets ready for revenue operations, will be certified by the independent safety assessor and Commissioner of Metro Rail Safety by August 2026.
