RUSSIA: Moscow Metro has taken delivery of a diagnostic train from Tvema. The Sinergiya-2 train is the next model of the first-generation Sinergiya train that is already in service on the metro.

Sinergiya-2 uses infrared sensors, thermal imaging and laser measurement, as well as high-resolution recording, to detect rail defects, overheated cables and leaks.

The train was unveiled at Sokol depot on Line 2 and will initially be used on that line.
