Indian Railways is implementing a massive traffic block on the Delhi–Ambala route starting May 31. This maintenance work impacts several elite trains, including the Vande Bharat and Shatabdi Express. Travellers heading toward Chandigarh should expect significant delays or partial cancellations throughout the week. Planning ahead is now essential for anyone using this busy rail corridor in North India.
The technical work focuses on bridge repairs and track maintenance near the Ambala Division area. This disruption is scheduled to last for several days, hitting both morning and evening schedules. Authorities aim to improve safety and long-term travel efficiency across this vital intercity link. Passengers must verify their train status before leaving for the station to avoid unnecessary waiting.

Impacted Vande Bharat and Shatabdi Services on Delhi–Ambala Route
Popular services like the New Delhi–Chandigarh Shatabdi face major timing changes and path diversions. Some trains will stay at various intermediate stations for thirty to ninety minutes during the block. Others might start from alternative stations or terminate early to facilitate these engineering works. The following table highlights key trains facing schedule adjustments or partial cancellations this summer.
| Train Number and Name | Service Impact during Block |
|---|---|
| 12046 Chandigarh Shatabdi | Delayed by 60 minutes |
| 22447 Una Vande Bharat | Rescheduled departure timings |
| 12012 Kalka Shatabdi | Regulated at previous stations |
For those already booked, the Indian Railway Catering and Tourism Corporation (IRCTC) offers refund options. If a train is fully cancelled, passengers receive a full refund automatically for online tickets. To check real-time updates, use the National Train Enquiry System (NTES) website or app. Frequent updates are also available through the official social media handles of Northern Railway.
Commuters can consider highway travel via the National Highway (NH) 44 as an alternative. While road travel might be slower during peak hours, it bypasses these rail blockages. If you must travel by train, try booking late-night services that are less affected. Coordinate with local transport in Chandigarh or Delhi to manage your journey smoothly now.
