Two coaches of the Delhi-bound Sikkim Mahananda Express derailed near Ara, Bihar, after overshooting a red signal. Officials say the incident caused partial rail disruption with no reported injuries and prompted an inquiry.

## Key takeaways

- Two coaches of the Sikkim Mahananda Express derailed near Ara in Bihar after overshooting a red signal.
- The incident occurred around 4 am; no injuries were reported at this stage.
- Rail traffic was partially affected, and the train arrived at its onward junction about four hours later than scheduled.
- An official inquiry will determine the exact circumstances behind the derailment.

## What Happened

The Sikkim Mahananda Express derailed two of its coaches in the early hours of a Sunday near Ara railway station in Bihar. Railway officials attributed the derailment to the train overshooting a red signal, with drivers misjudging the signal aspect. The incident occurred around 4 am local time. The train had departed from Ara after arriving there at 3:54 am, nine minutes behind its schedule, according to the National Train Enquiry System (NTES). The derailment disrupted rail traffic in the area, and the train ultimately reached Pt Deen Dayal Upadhyaya Junction at 10:49 am, about four hours later than its scheduled arrival time of 6:48 am.

The affected train is the Sikkim Mahananda Express, running as train numbers 15483/15484. The service operates on a daily basis and covers a long route, with a total distance of 1,659 kilometers and an official journey time of around 35 hours and 15 minutes. The train’s composition includes General Class, Sleeper Class, AC 3-Tier Economy, AC 3-Tier, AC 2-Tier, and First AC coaches. The derailment did not result in any injuries as per initial reports, though railway traffic experienced a disruption in the hours following the event.

## Why It Matters

The incident highlights operational risks associated with signal compliance and train handling on busy routes. While no injuries were reported, a disruption of rail traffic and a multi-hour delay can impact passenger schedules and cascading services on the corridor, especially on a Delhi-bound long-distance route that stops at numerous stations. The event underlines the importance of prompt investigations to determine whether signal aspects, driver judgment, or other system factors contributed to the overshoot and derailment, and to prevent recurrence.

## Background

The Sikkim Mahananda Express operates between Alipurduar Junction and Delhi Junction and makes stops at 59 stations along its route. The service runs weekly across all days and uses a fixed set of train numbers, 15483/15484, for its Delhi-bound journey. The full journey involves a lengthy schedule and multiple segments, with the corridor being a component of the broader East Central Railway network targeted by ongoing safety and operations oversight.
