The rail tensioner, developed by the Enerpred company, has successfully passed the tests on the section of the East Siberian Railway.

The tensioner is designed for tensioning rails up to 1200 m long with temperature compensation of ?25 ° C.

The collapsible design provides quick assembly and disassembly of the device, as well as its transportation by individual elements. High productivity of work is ensured by the use of pumping stations with an electric or petrol drive.
