| Work Detail |
The laying of track works have been initiated for the Mumbai-Ahmedabad High-Speed Rail (MAHSR) corridor with the start of the construction of the first reinforced concrete (RC) track bed in Surat.
Inspired by Japanese Shinkansen, the project has introduced the J-slab ballastless track system in India. The track system comprises pre-cast track slabs which support fastening devices and rails, with around 300 mm thickness, and is constructed in-situ for both up and down track lines on viaduct tops, with a width of 2,420 mm.
The RC anchors of 520 mm diameter and 260 mm height are provided to maintain precise alignment for train operations at speeds of up to 320 kmph. In material procurement, activity is underway and over 14,000 MT of JIS rails and 50 molds for casting track slabs have already been delivered. As per National High Speed Rail Corporation (NHRCL), dedicated factories with cutting-edge technology and infrastructure have been established to manufacture track slabs, ensuring highest quality and safety.
NHRCL will use specialized construction machinery includes rail feeder cars, slab laying cars, and cement asphalt mortar (CAM) laying cars. |
