Railways in Haryana began in the mid-19th century with the completion of tracks from Calcutta to Delhi in 1864. By 1870, the Scinde, Punjab & Delhi Railway connected Amritsar–Ambala–Jagadhri–Saharanpur–Ghaziabad, integrating Haryana into the broader railway network.
Rewari Junction, established in 1873, is the oldest railway station in Haryana. It became a junction in 1874 when the line extended to Alwar and further to Jaipur and Ajmer by 1875.
Haryana's railway network expanded significantly in the 20th century. The Delhi–Panipat–Ambala–Kalka line opened in 1891, and the Kalka–Shimla narrow gauge line was inaugurated in 1903. These lines were crucial for passenger and freight movement across northern India.
During British rule, Haryana's railways played a strategic role in connecting Delhi with Punjab and Rajasthan. The Southern Punjab Railway Company opened the Delhi–Bathinda–Samasatta line in 1897, linking Haryana to Karachi (now in Pakistan).
After independence, Haryana's railway infrastructure was reorganized under Indian Railways. The Northern Railway zone was created in 1952, followed by the North Western Railway (2002) and North Central Railway (2003). These zones manage Haryana's extensive rail network.
Electrification began in the 1970s and continued through the 1990s. Key sectors like Ghaziabad–New Delhi–Ambala and Chandigarh–Kalka were electrified by 2000.
Haryana is part of major railway corridors like the Eastern and Western Dedicated Freight Corridors. New lines such as the Chandigarh–Sahnewal and Rewari–Rohtak have enhanced connectivity.
The Rewari Steam Locomotive Shed and Rail Museum, established in 1893, preserves the legacy of steam locomotives. It houses vintage engines including the 1855-built "Fairy Queen" and offers guided tours and restoration workshops.
