Two Massive Roof Trusses Installed at Sabarmati Terminal During 7-Hour Traffic Block

In a major infrastructure milestone for Ahmedabad's rail network, railway authorities successfully installed two box-type steel roof trusses over tracks 1, 2, and 3 at the Sabarmati Terminal (Jail Road) during a strictly managed seven-hour traffic block. The precision engineering operation was completed within the approved timeframe without compromising safety or disrupting the surrounding live railway system.

The newly erected steel structures were placed over the areas designated for the terminal’s foot overbridges (FOBs). A 6-metre-wide and 16.68-metre-long truss was positioned at the arrival-side FOB on the Ahmedabad end, while a 6-metre-wide and 19.08-metre-long truss was installed at the departure-side FOB on the Rajkot end. Combined, the two box-type steel structures span a total length of 35.76 metres.

Heavy Machinery Deployed for Precision Lifting

Executing the heavy lift above active lines required significant machinery. Engineers deployed two 300-tonne-capacity cranes that operated in close coordination to lift, position, and align the heavy trusses over the tracks.

The equipment deployed during the traffic block included:

• Two 300-tonne-capacity main cranes
• Two hydras for local material handling
• One standby crane on site for emergencies
• Gas-cutting and welding equipment
• Scaffolding and dedicated connection-work facilities

62-Member Crew Manages Live-Track Safety

A specialized workforce of 62 personnel executed the operation. The ground team comprised 12 welding units, 20 skilled technicians, and 30 helpers working alongside the heavy crane operators to secure the connections within the seven-hour window.

Because the installation took place directly over operational tracks, railway authorities emphasized strict adherence to safety protocols to safeguard ongoing train operations and passenger movement throughout the duration of the work.
