In Astana, the laying of the first 500 meters of the rail track has been completed on the section of the LRT overpass between stations No. 116 and No. 117. This test stage will allow us to study the impact of winter weather conditions on the condition of the upper structure of the light rail track, the official website of the Mayor's Office of the city reports with reference to CTS.
The rail track includes a reinforcing frame, sleepers, rails and fasteners. The total length of the overpass is 22.4 km, and a double track will be laid along its entire length, which will ensure the passage of trains, convenience of their maintenance and repair work.
The laying of the path is carried out using modern technologies.
The standard track width of 1,435 mm ensures compatibility with international standards.
Seamless rail laying reduces noise from train wheels and minimizes vibrations.
Prestressed sleepers are protected from cracking, resistant to frost and thawing.
With the onset of the warm season next year, the active laying of rails along the entire length of the overpass will begin. In winter, the necessary materials are being prepared.
The completion of the laying of rails on the overpass is scheduled for 2025.
