Track construction in Gujarat progressing swiftly, rail welding begins on viaduct
The National High Speed Rail Corporation Limited (NHSRCL) has announced that the track construction work for the Gujarat portion of the Mumbai-Ahmedabad Bullet Train project is progressing “swiftly”. In its latest update on the project, the NHSRCL said that the welding of rails on the viaduct in Gujarat has started.
It added that the rails for the project have been procured from Japan, each measuring 25 metres. The rails are welded together by fusion welding (FBW) machines on the MAHSR viaduct. Together they will make 200 metres long rail panels. So far, 298 rails panels have been welded, constituting around 60 kilometres of rails.
The NHSRCL emphasised that the rail welding process is crucial for maintaining passenger comfort, as well as the durability and safety of the track for high-speed travel.
Before welding, the rail ends are grinded and undergo surface preparation to ensure a smooth, pristine surface for the critical joining of the rails. Each rail is inspected to ensure it meets the dimensional specifications required for welding.
