Rails special strength.
Rails high strength designed for difficult road sections and built for special operating conditions (for high speed trains with speeds up to 400 km/h, can withstand a temperature differential of 110 degrees Celsius and the load on the axle, at 30% above international norms).
Technology is in the process of development!
Rails high strength designed for difficult areas of roads and created for special conditions.
Developed rails category ДТ400ИК and ДТ350ВС400. They have successfully passed preliminary tests. Currently, these rails are preparing for certification testing.
Rails category ДТ400ИК is an improved version of rails ДТ370ИК designed for complex railway sections, and roads and showed the wear resistance is 13% higher than the rails in General purpose. Rails category ДТ400ИК are more hardness on the surface of and riding across the cross section of the head, and also superior to its predecessors due to optimum ratio of strength and plasticity. They are designed for special operating conditions: heavy traffic and difficult sections of track with steep curves with a radius less than 650 m.
Rails category ДТ350ВС400 designed for high-speed movement of trains with speeds up to 400 km/h. Their use will also be justified for highways with speed up to 250 km per hour, as these rails correspond to more stringent requirements on the manufacturing precision of the profile, have high ductility and toughness even at subzero temperatures. They can withstand a temperature differential of 110 degrees Celsius and the load on the axle, at 30% above international norms. These rails will provide the best ride high-speed trains. In addition, they comply with high requirements of safety.
