Frames for high-speed electric trains
In June 2025, we successfully tested a prototype frame of a non-motorized bogie for high-speed electric trains. Made of domestically produced C355 grade steel using high-precision welding, the frame is capable of maintaining impact toughness at low temperatures, which is necessary when operating rolling stock at high speeds in Russian climate conditions.
Its reliability has been certified by fatigue and resource tests on special test benches, during which the frame withstood 10 million cycles for each load mode without failure, which is equivalent to 30 years of operation on a high-speed line.
The bogie frame of a high-speed electric train is a base unit that receives lateral forces from the wheel pairs, traction and braking forces; it also bears all the loads from the weight of the body while the train is moving at speeds of up to 400 km/h.
