Signaling system issues or feedback failures (like track circuit issues or signal faults) can cause significant, immediate train stoppages and service delays.
If such technical faults frequently occur, passengers should check official Eastern Railway updates for real-time information.
The Green line that connects Howrah Maidan to Salt Lake Sector-V was inaugurated by Prime Minister Narendra Modi on August 22, last year.
Normal service was resumed at 5.32 pm.
