Bullet train track construction on track

The track construction work for the Gujarat portion of the Bullet Train project is progressing swiftly with the commencement of welding of rails on the viaduct in Gujarat.

Rails for the project are procured from Japan with a length of 25 meters each. These rails are welded together by the state-of-the-art fusion welding (FBW) machines, on MAHSR viaduct, to make 200 meters long rail panels. Till date, 298 such rail panels have been welded i.e., around 60 km of rails, the National High Speed Rail Corporation Ltd, said today.

The rail welding process is crucial for ensuring the passenger comfort, durability and safety of the track for high-speed travel:

• Before rail welding, the rail ends are grinded and surface preparation which ensures a pristine surface for the crucial joining of rails

• Each rail is checked to meet the dimensional requirements for welding

• Once the rails are perfectly aligned, they are joined together using flash butt welding technology.
