Commuters on the Mumbai Metro One corridor faced significant delays and overcrowding on Thursday after the operator imposed temporary speed restrictions following rail grinding work. The maintenance exercise, carried out in collaboration with Bangalore Metro, is aimed at improving track quality and ride safety. However, the resulting speed curbs slowed train movement, leading to bunching of services and crowd build-up at stations during peak hours.
Impact on Commuters
Passengers reported longer waiting times and packed trains, especially during the morning and evening rush hours. Many took to social media to express their frustration over the sudden disruptions. The operator has urged commuters to plan their journeys accordingly and allow extra travel time.
Safety Protocols
Officials confirmed that the restrictions are a standard safety protocol after such maintenance works and will remain in place for a limited period. “These measures are necessary to maintain track integrity and ensure commuter safety,” an official said, adding that efforts are on to minimise inconvenience. The rail grinding process involves smoothing the rails to reduce noise and vibration, which also extends the life of the tracks.
Coordination with Bangalore Metro
The collaboration with Bangalore Metro for this maintenance work highlights the sharing of best practices among metro systems in India. Similar speed restrictions have been implemented in other metro networks after such operations. The Mumbai Metro One operator expects normal services to resume once the tracks are deemed safe for regular speeds.
Commuters are advised to stay updated through official channels and consider alternative transport options if possible. The operator has apologised for the inconvenience and assured that every effort is being made to restore normalcy at the earliest.
