Eastern Railway (ER)

The Eastern Railway (ER) is one of the oldest and most historically significant zones in Indian Railways. It was officially formed on April 14, 1952, by combining several historical rail networks, including major parts of the famous East Indian Railway. In fact, the very first passenger train journey in eastern India ran under this regional network on August 15, 1854, carrying passengers between Howrah and Hooghly. Today, the zone's main administrative headquarters is located at Fairlie Place in the historic city of Kolkata, West Bengal. Because Kolkata was once the capital of British India, this railway network was built early on to connect major trade ports with the rest of the country.

The Eastern Railway covers a densely populated region in eastern India, spanning mainly across West Bengal, Jharkhand, and parts of Bihar. To handle its daily train operations efficiently, the zone is organized into four main administrative divisions: Howrah, Sealdah, Asansol, and Malda. Together, these divisions manage thousands of kilometers of tracks, hundreds of local stations, and major repair workshops like those in Kanchrapara, Liluah, and Jamalpur. The zone handles everything from heavy suburban train traffic around metropolitan areas to long-distance trains traveling across regional state borders.

Eastern Railway operates two of the biggest, busiest, and most iconic train stations in India: Howrah Junction and Sealdah Station in Kolkata. The Sealdah division runs one of the largest local suburban train networks in the world, carrying millions of daily commuters to work and school. The zone also manages famous long-distance trains, including the historic Howrah Rajdhani Express, Poorva Express, and Darjeeling Mail. Additionally, Eastern Railway serves as an essential gateway connecting Kolkata to northern, southern, and northeastern parts of India, while also supporting cross-border train links to neighboring Bangladesh.
