From today, September 21, Indian Railways begins non‑interlocking work near Mokama’s Rajendra Bridge. Widespread cancellations, diversions, and short terminations follow through October 4. Official advisories flag 845 services impacted overall during the block period. They include more than 300 cancellations and 384 diversions on busy Bihar corridors. Expect rolling changes as junctions are cut over during commissioning work. ECR’s advisory spans multiple divisions and long‑distance links across adjoining zones.
The first wave arrives today with at least 12 cancellations notified for September 21. Counts climb daily this week, according to public lists shared by railways and media. Expect 13 on September 22, 15 on September 23, and 21 on September 24. The curve peaks toward September 27, when 31 services face cancellation under the block. Further spikes follow, with 24 on September 25 and 29 on September 26.

Rajendra Bridge NI block: zones and key routes hit
The block centres on East Central Railway’s Danapur Division, spanning the Rajendra Setu approaches. Crews are integrating the new double‑line bridge at Upper Hathidah, Tal, Rampur Dumra and Simaria. Barauni’s yard also sees cutovers, rippling delays onto trunk links toward Howrah and Delhi. Expect Patna–Mokama–Kiul–Barauni movements to slow, with diversions lengthening travel times and slack.

If your booked train is cancelled, e‑ticket refunds are automatic; counter tickets follow notified timelines. For diversions skipping your boarding station, file an online Ticket Deposit Receipt within seventy‑two hours. Short terminations also require Ticket Deposit Receipt filing within prescribed windows for partial fare. Use National Train Enquiry System app and integrated helpline 139 for live exceptions before heading out.
Build extra buffers this week, especially across Patna, Barauni, Kiul and Mokama gateways. Reconfirm coach positions and boarding platforms, because diversions can alter rakes and halts. Check status on travel day, then again three hours before departure when charts settle. With commissioning due by October 4, disruption should ease as daily cutovers stabilise.
