Accident on the works,

A parapet segment fell from the viaduct onto vehicles at Mulund: one man died and three people were hurt.

On LBS Road near Mulund Fire Station, at pier P196. MMRDA fined the civil contractor, the Reliance Infrastructure-Astaldi joint venture (named 'RAJV Milan Infra' by News On AIR), Rs 5 crore, and the general consultants (DB Engineering, Hill International and Louis Berger) Rs 1 crore; the consultants' services ended on 18 Feb 2026. An MMRDA executive engineer was suspended. MMRDA's inquiry, as Free Press Journal reported it on 26 Mar 2026, found that a welder cut the temporary supports of a newly placed segment before it was joined, and no design, material or workmanship fault; work on Line 4 was then cut back to safety work only. No MMRDA document on the inquiry was found.

Who is building it

Trains

The trains are ordered. Alstom is building 39 six-car trains for Lines 4 and 4A. They are part of one contract held by L&T, with the signalling, platform screen doors and depot machinery.

The first Line 4 train in Alstom's factory shed: a glossy black front with a green stripe sweeping along the roof, blue and green panels at the doors, grey sides, car number D4P001, and a worker in a hard hat in the cab.

Package CA-234, held by L&T: 39 trains of 6 cars (234 coaches). The award value is not published; the tender estimate was ₹4,297.49 crore. ReportedRailway Gazette (opens source in a new tab)

First train: The first train was unveiled at Alstom's factory at Sri City on 14 Oct 2026, built in 14 months. Alstom expects to ship it by the end of November and to reach Mumbai in the first or second week of December 2026. ReportedRailway Gazette (opens source in a new tab)

Maintenance: 17 years of maintenance under the same contract, paid for by MMRDA; the KfW loan pays for the design and build. ReportedThe Metro Rail Guy (opens source in a new tab)

Driving: Driverless, at the highest grade of automation (GoA4), with Alstom's Urbalis Forward CBTC signalling. ReportedRajendra B. Aklekar (opens source in a new tab)

Built in India: Designed at Alstom's engineering centre in Bengaluru and built at Sri City in Andhra Pradesh, with propulsion from Coimbatore and bogies from Savli in Gujarat. ReportedRailway Gazette (opens source in a new tab)

On board: Airflow-based cooling, wheelchair spaces and bicycle racks, which Alstom calls a first for its trains in India. ReportedMetro Rail News (opens source in a new tab)

Tests before service: After it arrives, each train must pass RDSO and CMRS tests, including runs up to 90 km/h, braking, ride and oscillation trials. Alstom says its signalling work is done. ReportedPSU Watch (PTI) (opens source in a new tab)

Until they arrive: MMRDA plans to open the first stretch with trains from Lines 2 and 7, as reported, and to replace them once the Alstom trains are tested. Alstom's contract milestone for passenger service with its trains is August 2027. ReportedPSU Watch (PTI) (opens source in a new tab)

Where they will be kept: The first 20 trains at the Mandale depot (Line 2B), which also holds the operation control centre, and the other 19 at the Kasheli depot (Line 5), linked to Line 4; a backup control centre at Mogharpada. Line 4 has no depot of its own yet. Sources conflictRajendra B. Aklekar (opens source in a new tab)
