At the end of July, an open scientific and engineering conference was held at the All-Russian Scientific Research Institute of Railway Transport (VNIIZhT, the town of Shcherbinka) summing up interim test results of Lastochka Premium (ES2GP) higher-speed EMU train manufactured by the Ural Locomotives plant.

The EMU has successfully completed preliminary tests and a portion of acceptance tests confirming that the new version train – its traction and braking performance among other things – meets the requirements as set out in the Product Development Specification.

The Lastochka Premium (ES2GP) EMU train is the first Russian passenger train fitted with the all-new Russian-made microprocessor-based control and diagnostics system (MPSUiD). Being based on the advanced Ethernet system bus, MPSUiD offers data security and backup at par with the system’s foreign counterparts.

According to Nina Nikiforova, VNIIZhT’s Leading Research Fellow, the greater part of the train control system validation is already complete. “The completed preliminary tests and the portion of acceptance tests have confirmed that MPSUiD meets the requirements of the Product Development Specification and the regulatory documentation in terms of both its performance and its functional safety” said Ms. Nikiforova. “The EMU has fewer connections between its cars, which contributes to increased reliability. The new EMU control system allows for a simpler automated train driving system and for the use of equipment sourced from various suppliers. The system allows collecting, analyzing and storing all the diagnostics information on board each railcar. ”

The use of the Russian control system has allowed to integrate into the EMU a number of Russian-engineered peripheral systems that control the braking, the passenger cabin climate, the passenger information systems, and the exterior doors.

“The new microprocessor-based control and diagnostics system envisions the placing of control units on board each railcar allowing us to vary the number of cars in a train thus reducing the train operating costs on the lines with lower passenger traffic levels” said Vitaliy Brekson, Head of R&D Department at Ural Locomotives. “We expect the microprocessor-based control and diagnostics system testing to be completed by the end of September 2016.”

The plant’s specialists continue to enhance the system performance based on results of the tests.
