'Peregrine Falcon'), also known as Velaro RUS EVS, is a Russian gauge high speed electric express train.

The trains started regular service on the Saint Petersburg–Moscow Railway in December 2009[1][2] at a maximum speed of 250 km/h (155 mph).

[6] The trains were ordered to connect Moscow with Saint Petersburg[7] and later Nizhny Novgorod at a speed of up to 250 km/h (155 mph).

[9] Four single-voltage ("EVS1", 3 kV DC powered, trainsets 5-8) trains entered passenger service at the end of 2009 on the Moscow – St Petersburg route, with the dual-system trains (EVS2, trainsets 1-4) entering service on the Nizhny Novgorod route on 30 July 2010.

Introduction of Sapsan initially caused cancelation of affordable daytime trains between Moscow and St Petersburg.

New Lastochka commuter trains were introduced on the Moscow – Tver[15] and St Petersburg – Bologoye routes.
