String rail

The basis of our technology is an innovative string rail. String-rail, or rail-string is an ordinary concrete or steel reinforced beam or truss with a rail head and additionally reinforced with pre-stretched strings.

Variant of string rail structure

Flat rail head and cylindrical steel wheel ensure minimal energy consumption for movement.

String rail combines the properties of a flexible cable on a large span between supports and a rigid beam on a small span — under the wheel of an electric rail car and above the support.

Иконка листаEco-friendliness

1. Low resource and energy consumption at all stages of the life cycle of a high-speed transport complex (designing, construction, operation and dismantling)

2. The elevated speedy route does not violate the terrain, biogeocenosis and biodiversity of the adjacent natural urban area

3. Our track does not destroy fertile soil and the vegetation that grows on it

4. Our track does not interfere with the movement of ground and surface water, movement of people, domestic and wild animals, operation of construction and special equipment

Иконка защиты
Reliability and safety

1. Anti-derailment system at the high-speed rolling stock

2. Tenfold safety margin of carrying string elements in the transport overpass

3. Resistance to slippery surface and icing, snow drifts, fogs, dust and sandstorms

4. Reliable operation at all extreme air temperatures

5. High resistance to vandalism and terrorist attacks

6. Resistance to natural disasters with a special design and minimal cost increases
