Sokol (Сокол, Russian for "falcon") was a planned high speed train in Russia.[1] It was to be a successor of the ER200 for use on the Moscow–St. Petersburg mainline, and was designed to operate at a cruising speed of 250 km/h. A prototype was built in 2000 and tested by Russian High Speed Railway Shareholding Co.[2]

The Sokol project was cancelled in 2002.[3] Instead of a Sokol-based design, high speed trainsets (named Sapsan) based on the Siemens Velaro were procured from Siemens in Germany.[4] The Sapsan trains have been operating on the Moscow-St.Petersburg line since December 2009.
