The Eastern Bengal Railway company was formed in 1857 for the construction and working of a line from Calcutta to Dacca, with a branch to Jessore. The construction of the long broad gauge line began in 1859 and was completed in stages up to Kushtia by 1864 but  the planned branch to Jessore was not built. The company also acquired a steam vessel service operating between Kushtia and Dacca on the Padma river. In 1871 the line was extended from Poradaha to a new ferry terminal at Goalundo Ghat, about east of Kushtia and reducing the river trip to Dacca. and becoming the main line of the Eastern section of EBR. With the successful construction and opening of the Hardinge Bridge in 1915 and gauge conversion of the Santahar–Parbatipur–Siliguri line from 1924 to 1926, the Calcutta–Siliguri broad gauge line was completed and became the main  line of the Eastern section of EBR. The Bengal Central Railway company constructed two broad gauge lines: one connecting Ranaghat and Bangaon () in 1882 and the other connecting Dum Dum with Khulna (now in Bangladesh), via Bangaon () which opened in stages and was completed in 1884. These lines were merged with Eastern Bengal Railway in 1904, with the Sealdah–Bangaon–Jessore–Khulna line becoming the main line of the Central section of EBR. The Martin's Light Railways company constructed and opened the long, narrow gauge Ranaghat–Krishnanagar Light Railway line from Aistalaghat (near Ranaghat on the right bank of  Churni river) to Krishnanagar via Shantipur in 1899. This line was amalgamated with EBR on 1 July 1904. EBR further extended the line from Krishnanagar to Nabadwip Ghat and opened the line for traffic from 30 June 1926. EBR further built a long broad gauge extension from Ranaghat to the left bank of Churni River on 1902. In 1925 an alternate broad gauge line was built from Kalinarayanpur (Churni Bridge) to Shantipur and the old gauge line between Shantipur and Aistola Ghat was abandoned. The long Murshidabad Branch railway was constructed by EBR from Ranaghat to Lalgola Ghat in stages  from 1905 to 1907. MLR also constructed and opened a long narrow gauge line from Barasat to Basirhat in 1905, known as the Barasat–Basirhat Light Railway . It was further extended via Taki to Hasnabad (Chingrighata) in 1909. A long extension was built from Beliaghata Bridge on the Barasat–Basirhat line to Patipukur in 1910. This was further extended to Belgachia in 1914 and was known as the Shyambazar Branch. On the southern side, the Calcutta and South-Eastern Railway was formed in 1859 to connect Calcutta with on the Matla River. It constructed and completed the long line on  15 May 1863. It was the first railway track on the eastern bank of the Hooghly River and ran from what was then the Beliaghata railway station (presently ) to on the Matla River via and . In 1868, CSER having suffered extensive losses due to floods and other problems, sold the line to the Indian government (management then being leased to the Eastern Bengal Railway) and the company was dissolved in March 1870. Thus the line became a part of the Southern Section of the Eastern Bengal Railway. In 1883, a branch line to Diamond Harbour via and Magrahat was constructed  from on the Sealdah–Canning line of the Eastern Bengal Railway. This line, from Sealdah to Diamond Harbour, then became the main line of the Southern section of the Eastern Bengal Railway. The Budge Budge branch line was initially sanctioned in 1886 as a line to connect with the Kidderpore Docks. Sanction to an extension to Budge Budge was given in 1888 and the whole of long line from to was opened on 1890 by the Eastern Bengal Railway. The Calcutta Ports Commissioner's Railway built a branch line from Kidderpore Docks to Majerhat on 1893. It further constructed a  branch line from the subsidiary marshaling yard at to King George's Dock (renamed to Netaji Subhas Dock in 1973) in 1928. In 1928, a long line from on the Diamond Harbour branch line to via was constructed by the Eastern Bengal Railway and became a branch line of its Southern section. In 1942, EBR was merged with the Assam Bengal Railway to form the Bengal and Assam Railway . Post the partition of India in 1947, the Eastern and Central sections of EBR were divided between India and East Pakistan. The direct connection between South Bengal and North Bengal was  affected as the Calcutta–Siliguri line was snapped resulting in Haldibari–Chilahati and Gede–Darsana becoming international transit points for trains. In the Central section, Petrapole railway station was created as the terminus on the Indian side while the Benapole railway station became the terminus in the East Pakistani side of the line. All the railway lines east of Hooghly, south of Lalgola and west of East Pakistan that were under EBR were reorganised to be under the Sealdah division. The Sealdah division became a part of the Eastern Railway after the reorganization of railway zones on 14 April 1952 . The Barasat–Basirhat Light Railway closed down in 1955 due to increasing losses. However a new broad gauge line was built in a new alignment between Barasat and Hasnabad from 1957 to 1962. The Shyambazar branch line was abandoned. In an effort to give access to remote areas and promote new growth areas, the long Lakshmikantapur–Namkhana line project was sanctioned in 1987-88 amongst other projects. The line was extended up to Kulpi by 1992 and was completed till Kakdwip by 2001. The Kakdwip–Namkhana section was completed by 2004. The Baghbazar-Prinsep Ghat line was rehabilitated and commissioned  for passenger traffic on 15 August 1984 and services were subsequently extended northwards towards Tala and finally to Dum Dum by 17 June 1990. The Prinsep Ghat-Majerhat elevated section was commissioned in 2005 thus completing the Circular railway line. List of major railway stations by commercial importance.
