Ahmedabad (Gujarat) [India], April 22 (ANI): Track set up work on the Mumbai-Ahmedabad Bullet Train challenge is progressing steadily, with the adoption of the superior J-Slab ballastless observe system primarily based on the Japanese Shinkansen know-how, which is getting used for the primary time in India, in accordance with an official assertion by the National High Speed Rail Corporation Limited (NHSRCL).
The NHSRCL said that the J-Slab observe system contains 4 key components–RC Track Bed, Cement Asphalt Mortar (CAM), Pre-cast Track Slab, and rails with fasteners–designed to assist high-speed practice operations.
To assist the manufacturing of observe slabs, two state-of-the-art Track Slab Manufacturing Facilities (TSMF) have been arrange at Kim close to Surat and Anand in Gujarat. These amenities are producing high-grade concrete slabs with exact dimensions to make sure a constant provide for the challenge.
The slabs are saved on the manufacturing unit and transported through trailers to Track Construction Bases (TCBs), which act as operational hubs for dealing with supplies, equipment, and tools each on the bottom and on the viaduct.
At current, ten TCBs are operational–four between Surat, Bilimora and Vapi, and 6 between Vadodara, Anand and Ahmedabad.
National High Speed Rail Corporation Limited (NHSRCL) is a government-owned entity, particularly a ‘Special Purpose Vehicle’ (SPV). It is a three way partnership firm involving the Central Government by way of the Ministry of Railways (50% fairness) and the state governments of Gujarat (25%) and Maharashtra (25%).
According to the assertion, vital progress has been made in observe development. A complete of 185 route km of RC Track Bed has been laid, whereas 188 route km of observe slabs have been manufactured. Additionally, observe slabs have been laid and CAM injected throughout 70 route km.
The firm additionally added that the observe set up course of is totally mechanised and makes use of specialised equipment designed as per Japanese development practices, with most tools manufactured in India.
Among the important thing machines getting used is the Flash Butt Welding Machine (FBWM), which welds 25 m lengthy 60 kg rails into 200 m lengthy panels on the TCB. These welded rails bear strict approval processes to make sure they’re match for high-speed operations at 320 kmph. Training and certification for rail welding and inspection have been carried out by the Japanese firm JARTS.
The Track Slab Laying Car (SLC) is used to carry and place precast slabs onto the viaduct, with the capability to deal with 5 slabs at a time. Meanwhile, the Rail Feeder Car (RFC) is used to move and lay 200 m lengthy rail panels over the observe mattress.
After slab placement, the Cement Asphalt Mortar Injection Car (CAM Car) is deployed to inject the CAM combination beneath the slabs, making certain correct alignment and levelling of the observe.
The adoption of superior know-how and mechanised processes is anticipated to reinforce the effectivity and precision of observe set up for India’s first high-speed rail hall. (ANI)
