A fire near the railway tracks between Nallasopara and Virar damaged signalling equipment late on November 8, forcing Western Railway to operate Mumbai-bound trains under restricted signalling procedures and causing delays to suburban and some long-distance services.
The fire broke out at about 11.20pm in the railway track area and was extinguished within 30 minutes, according to a report by the Times of India citing railway officials. The blaze damaged multiple track circuits in the section, resulting in a signalling failure on the route towards Mumbai.
With the affected equipment not functioning normally, up trains are being operated by passing two signals under prescribed railway rules. The procedure is intended to allow train movement during a signalling disruption, but it requires trains to operate under controlled conditions and can reduce the speed and throughput of services through the affected section.
The disruption has affected Western Railway’s suburban operations as well as some long-distance trains heading towards Mumbai. The Nallasopara-Virar section is part of the heavily used northern suburban corridor, where local services share a route with longer-distance trains. A failure of signalling equipment in this section can therefore affect multiple categories of rail services rather than a single train or station.
The incident highlights the operational dependence of the corridor on track circuits and signalling systems. These systems help railway authorities establish whether sections of track are occupied and support the safe movement of trains. Damage to several circuits requires train movements to be managed through alternative operating procedures until the equipment is repaired and normal signalling is restored.
Railway officials were attending to the signalling failure after the fire and working to restore regular operations. The supplied report did not provide details on the cause of the blaze, the extent of damage to the equipment, or a specific timetable for full restoration.
Passengers travelling from the Virar and Nallasopara areas towards Mumbai were facing delays across affected services as railway teams worked on the damaged signalling infrastructure. Normal operations will depend on the completion of repairs and the return of the track circuits and signals to service.
