Under the contract, which was signed in the presence of Moscow regional governor Mr Andrei Vorobyov, DMZ will deliver four 12-car trains and 22 11-car sets by the end of this year.

The air-conditioned trains will be equipped with LED lighting, CCTV, and a remote diagnostics system.

TMH says the trains will replace life-expired emus on some of the busiest suburban routes in the Moscow area.
