The Most Appropriate Solutions for Moscow -Yekaterinburg HSR Project: Definition of the High-Speed EMU Train Key Parameters

The paper contains synopsis of High Speed Rail (HSR) projects in Russia (inclusive of high-speed rolling stock) for the years 1974 - 2014. There are discussed basic outcomes of high-speed EMU trains Sapsan and Allegro operation between Moscow, St. Petersburg, Nizhny Novgorod and Helsinki. A strategic study on the implementation of a 1520mm-gauge High Speed Rail network in Russia with the maximum speed up to 400 kph was launched by the JSC RZD in 2013. The paper presents information about Moscow - Yekaterinburg HSR-2 line inclusive of main infrastructure characteristics and applicable technical requirements to the HSR EMU train covering its configuration, vehicle gauge, tractive characteristics, aerodynamics, electrical power supply system and passenger car interiors. The discussed technical requirements were developed and approved by RZD on June 8, 2015. Definition of the high-speed train key parameters and specifications is based upon ingenious method. To decide on the concept of the train and its main technical characteristics there were investigated its recently developed closest analogues with design speed ranging from 360 to 400 kph. Target values of basic parameters were estimated with allowance for the specific requirements imposed to the Russian high speed train in the context of agreed HSR-2 standards. Given that the designing phase of the Moscow - Kazan high speed railway is underway the defined key train parameters and specifications are recommended for use in further calculations. Basic provisions of the paper were first unveiled in 2015 at the 9th UIC World Congress on High Speed Rail in Tokyo.
