Kolkata Metro has stabilised Blue Line operations following a temporary approval from the Commission of Railway Safety (CRS) to allow trains to switch tracks at Kavi Subhash station. The southern terminal had been partially closed after cracks were detected in platform-supporting piers, forcing Shahid Khudiram station to act as the terminal despite lacking a crossover. Previously, trains could not depart Shahid Khudiram before the previous train completed its turnaround at Kavi Subhash, causing delays. With 172 daily trains now able to switch tracks efficiently, operational accuracy has reached around 98 per cent, improving commuter reliability.
Kolkata Metro has recently received temporary approval from the Commission of Railway Safety (CRS) to improve operations on the Blue Line, helping the network maintain about 98 per cent operational accuracy. This comes after the southern terminal, Kavi Subhash station, was partially closed due to cracks in platform-supporting piers. Since the closure, the southern terminal operations were shifted to Shahid Khudiram station, which does not have a crossover facility. Advertisement
Previously, CRS rules required that no train could leave Shahid Khudiram until the previous train had completed its turnaround at Kavi Subhash. This was a safety measure because the viaduct slopes down from Shahid Khudiram to the ground-level Kavi Subhash station. The restriction limited train movements and caused delays, affecting passengers on one of Kolkata's busiest commuter corridors.
To manage the situation, Metro Railway had run empty trains between the stations to use the Kavi Subhash crossover. Timetable adjustments, including terminating 33 services at Tollygunge, were attempted, but these caused passenger dissatisfaction as many had to disembark earlier than their destinations, and service delays persisted.
With CRS lifting the restriction temporarily, all 172 scheduled trains can now proceed to Kavi Subhash to switch tracks. Trains can now move in both directions efficiently, even while empty trains travel in the opposite direction. This adjustment has allowed the Metro to restore near-normal service punctuality and ease commuter congestion.
The temporary approval addresses operational challenges caused by the absence of a crossover at Shahid Khudiram and the past closure of Kavi Subhash. Metro officials are continuing to plan longer-term infrastructure solutions to ensure smoother and more reliable operations in the future.
