Howrah–Kharagpur Line
The Howrah–Kharagpur line is part of the Howrah–Nagpur–Mumbai line, Howrah–Chennai main line and Kolkata Suburban Railway. Geography The line runs through the plains of West Bengal. From Howrah, it is first the Gangetic Plains and then the basins of the Damodar, Rupnarayan and Kangsabati, thereby traversing Howrah, Purba Medinipur and Paschim Medinipur districts. Kolaghat Thermal Power Station, with its six tall chimneys, one for each of the 210 MW units, is a landmark on this line. Haldia dock complex handled 31.015 million tonnes of traffic in 2011–12. Haldia Refinery, one of the eight operating refineries of Indian Oil Corporation, was commissioned in 1975. Haldia Petrochemicals, a modern naphtha based petrochemical complex and the second largest project of its kind in India, has been a catalyst for the development of a large number of downstream industries. History Bengal Nagpur Railway opened to traffic its main line from Nagpur to Asansol in 1891. Sini, ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate th ...

Bengal Nagpur Railway
The Bengal Nagpur Railway was one of the companies which pioneered development of the railways in eastern and central India. It was succeeded first by Eastern Railway and subsequently by South Eastern Railway. History The opening of the Mumbai–Thane line in 1853 marked the beginning of railways in India. Extension of the railways was set off throughout the country. On the north-eastern side of Mumbai, the Great Indian Peninsular Railway line was extended up to Bhusawal and then split in two. While one track led to Nagpur, the other to Jabalpur to connect with the East Indian Railway line from Allahabad to Jabalpur, thereby connecting Mumbai and Kolkata. The great famine of 1878 provided an opportunity for the construction of 150 km long meter gauge link called the Nagpur Chhattisgarh Railway in 1882 connecting Nagpur with Rajnandgaon. The Bengal Nagpur Railway was formed in 1887 for the purpose of upgrading the Nagpur Chhattisgarh Line and then extending it via ...
