Where five lines converge
Ambala Cantonment Junction carries the station code UMB, an echo of the old spelling Umballa used in British records. It is the busiest station in Haryana: about 300 trains start, terminate or run through it every day, and it is counted among the top hundred booking stations of Indian Railways. The station is on the Grand Trunk Road in Ambala Cantonment and is the headquarters station of Northern Railway's Ambala division.
Five routes radiate from here:
- Delhi–Kalka line, south to Delhi and north to the Shimla foothills
- Moradabad–Ambala line, east via Saharanpur
- Ambala–Attari line, west to Ludhiana, Jalandhar and Amritsar
- Ambala–Bathinda line, into south-west Punjab
- Ambala–Una Himachal line, towards Himachal Pradesh
From the Scinde railway to electrification
Railways reached Ambala in 1870, when the Scinde, Punjab & Delhi Railway completed its 483 km line linking Amritsar, Ambala, Saharanpur and Ghaziabad. In 1891 the Delhi–Panipat–Ambala–Kalka line opened, giving Ambala its north–south role, and the present junction dates from that year. Electric traction came in the late 1990s: Ambala–Saharanpur in 1996–98, then Kurukshetra–Ambala and Ambala–Chandigarh in 1996–99.
A station shaped by the cantonment
Ambala grew around one of the largest military cantonments in north India, and the railway served troops and supplies as much as civilians. A diesel loco shed here maintains WDS-4 shunting engines used in yard work across the division.
Platforms and a French partnership
UMB has 7 platforms on 10 tracks, with plans to expand to 9, at an elevation of about 273 metres. Its modernisation has an unusual international angle: the French national railway SNCF has been involved in a station development study supported by the French agency AFD, with assistance worth around 7 lakh euros in kind.
Shatabdi country
After leaving New Delhi, most northbound Shatabdi Express trains make Ambala their first major stop, before branching towards Chandigarh and Kalka or onwards to Amritsar. The station is also on the route of Vande Bharat services into Punjab and Himachal. Timings for each service are on Railopedia's schedule page.
Changing trains at Ambala
- Travellers to Shimla often change here for a Kalka-bound train; leave time to cross platforms.
- Ambala City, a separate station a few kilometres away, serves the old town; don't confuse it with Ambala Cantt.
- Kurukshetra, of Mahabharata fame, is a short ride south on the Delhi line.
