The prototype of a broad - gauge high-speed train of the Russian Railways (RŽD) was carried under the series designation ЭС250 (German transcription ES250) . He was also known as Sokol ( Russian Сокол [ ˈso̞kəɫ ] ( ), in German falcon ).
A 350 km / h variant of the train was envisaged as the ES350 . This was to be used on a (unrealized) new line between Moscow and St. Petersburg.
history
The planned twelve-part series ЭС250 should operate as the successor to the series ЭР200 (ER200) on the St. Petersburg – Moscow railway and reach a cruising speed of 250 km / h (planned maximum speed: 300 km / h). A six-part prototype was built by Transmasch in Tichwin between 1997 and 1999 and presented to the public on July 28, 1999.
In early 2001, the trial was a six-car train prototype on the test ring shcherbinka . The further development of this series was stopped in 2002 due to numerous defects in the immature design and the entire project was discontinued in 2004. The single purchase price was about 19.3 million US dollars.
The series trains should consist of 12 cars and (depending on the division into 1st and 2nd class) have between 688 and 832 seats. In addition to two control cars , four powered cars, four transformer cars and two trailer cars were provided. A total of 16 traction motors (3-phase asynchronous motors ) should - depending on the desired maximum speed - provide a total output of 6,880 or 10,880 kW. According to the Russian Ministry of Railways from 2001, there was a need for 100 Sokol multiple units by 2010. They should connect the Russian capital with St. Petersburg, Sochi , Warsaw and Berlin .
More than 60 companies and organizations were involved in the project.
technology
Similar to the German ICE 3 , the ЭС250 series did not have a powered end car. The drive technology and other components were distributed under the floor to all cars. The car bodies were made of aluminum. The equipment included vacuum toilets, a bar and air conditioning in two different car classes. The train's brakes were electrodynamic, pneumatic and designed as a magnetic rail brake. After several test drives, the six-part Sokol reached a speed of over 200 km / h for the first time on May 27, 2000 on the St. Petersburg – Moscow railway line . A twelve-part train for up to 800 passengers was planned.
Replacement of the Sokol
Instead of Russian in-house production of the Sokol, in 2006 the Russian State Railways signed a supply contract with Siemens Mobility for eight ten-part Velaro multiple units, which have been running between Saint Petersburg and Moscow as “ Sapsan ” since December 17, 2009 .
