Indian Railways is currently grappling with significant operational disruptions across the country this July 21, 2026. A combination of torrential monsoon rains, severe flooding, and a goods train derailment has forced the national transporter to cancel, divert, or reschedule dozens of passenger services. Passengers are urged to stay updated as authorities work to restore normalcy across affected zones.
Key updates for travelers include:
• 53 passenger trains impacted in the Delhi Division due to a goods train derailment.
• 16 train cancellations and 24 diversions reported in the Northern Railway zone.
• Kalka-Shimla toy train services suspended due to adverse weather.
• Over 30 trains affected in Assam following severe flooding of the Dikhow River.
• Passengers advised to use the NTES App or call Rail Madad Helpline 139 for real-time status.
Delhi Division Operations and Derailment
The rail network in the capital region is facing a dual challenge. A goods train derailment involving six loaded wagons on the Ghaziabad-New Delhi section has caused major bottlenecks. Northern Railway officials, including the Divisional Railway Manager, are currently on-site to oversee track restoration. With the India Meteorological Department (IMD) issuing a yellow alert for Delhi through July 23, passengers should expect continued fluctuations in schedules.
Impact on Hill Railways and Northeast Operations
In the north, the iconic Kalka-Shimla route has been hit, with the 52459/52460 (Him Darshan) and 52455/52456 (Himalayan Queen) trains cancelled for July 21. Meanwhile, the situation in Assam remains critical. The Northeast Frontier Railway (NFR) has been forced to suspend movement between the Simaluguri-Namtiali and Simaluguri-Selenghat sections as floodwaters from the Dikhow River submerged tracks. Long-distance services bound for Dibrugarh and Tinsukia are being diverted via the Rangiya-Rangapara route to bypass the flooded zones.
Nationwide Weather Alerts
Coastal areas are also on high alert. Mumbai is currently under an Orange Alert from the IMD, with heavy to very heavy rainfall expected to impact suburban and long-distance rail operations throughout the day. Travelers are strongly encouraged to verify their train status before heading to the station, as weather conditions remain volatile across several states.
