St Petersburg Metro awarded TMH subsidiary Oktyabrsky Electric Car Plant (OEVRZ) a Roubles 10.5bn ($US 161m) contract last August to supply 20 eight-car trains for the city's 113km 1524mm-gauge metro network.

The trains feature LED headlights and interior lighting, microprocessor control and diagnostics, internal and external CCTV cameras, and wider doors. Each train is formed of six powered vehicles and two trailers.

The order is being funded through the city of St Petersburg's 2015-2020 transport strategy, which was approved in June 2014, as well as the metro's own investment programme.

St Petersburg metro is due to receive three trains this year, with the final sets scheduled for delivery in 2020.
