The East Indian Railway Company (EIR) was a railway company that operated in British India during the nineteenth and early twentieth centuries. It was responsible for constructing and operating one of the earliest and most important rail networks in the subcontinent, linking Calcutta (now Kolkata) with the cities of the Gangetic plain and northern India.

The company was promoted in London in the mid-1840s by a group of British investors, with Rowland Macdonald Stephenson as one of its leading advocates. After negotiations with the East India Company and the British government, EIR was granted a contract to construct a railway from Calcutta into the interior, with the long-term aim of reaching Delhi and connecting to the cotton-growing and coal-bearing regions of India.
At its fullest extent, the East Indian Railway operated a trunk route running from Howrah, opposite Calcutta, through Bardhaman, Asansol, Dhanbad, Gaya, Mughalsarai, Allahabad, Kanpur and Aligarh to Delhi. Important branches served Patna, Lucknow, Agra and the Jharia coalfield. The system was built to the Indian broad gauge of 5 ft 6 in, a standard that EIR helped to entrench across northern India.
The company maintained major workshops at Jamalpur in Bihar, established in 1862, which became one of the largest locomotive and carriage works in Asia and a centre of mechanical engineering training in India.
The East Indian Railway was instrumental in shaping the economic, administrative and demographic geography of northern and eastern India. It provided rapid movement of coal from the Raniganj and Jharia fields to Calcutta, supported the jute and grain trades, facilitated troop movements, and accelerated urbanisation along its route. Towns such as Asansol, Kharagpur (linked via connecting lines), Jamalpur and Mughalsarai grew significantly as railway settlements. The company's standards of construction, signalling and workshop practice influenced the wider development of the Indian railway system.
After nationalisation and the 1952 zonal reorganisation, the EIR's main line from Howrah to Mughalsarai became the core of the Eastern Railway, while the section from Mughalsarai to Delhi was incorporated into the Northern Railway. Several heritage structures, including the Jamalpur workshops, Howrah station precinct and various station buildings along the route, survive as reminders of the company's role in nineteenth-century infrastructure development.
