Situated on the west bank of the Hooghly River and linked to Kolkata by the Howrah Bridge, Howrah Railway Station is one of the largest railway terminals in the world and also the busiest and second oldest station and having one of the largest railway complexes in India. Initial plans for the first Howrah station were submitted by George Turnbull the Chief Engineer of the East Indian Railway Company on 17 June 1851 and completed by 1854.
It was expanded in the 1980s, bringing the platform track count up to 23. It is slated to get an additional 15 platform tracks by the next decade to bring it up to a total of 38 platforms. In the technique and the performance of the railways a railway station is a place of service, bordered by protective signals, which take place in the operations of the movement of trains precedence, diversions or junctions and access to the network of passenger and goods.
A railway station is a facility in which the activities take place involving passengers arrivals and departures, goods shipping and receiving, railway operations movement and maintenance of rolling stock. From the engineering point of view, a train station is equipped with at least two tracks and one exchange, to have the ability to make crosses or precedence between trains and to compose and decompose the trains.
Depending on the position of the passenger with respect to the main beam of the tracks can be distinguished transit stations interim or nodal, in which trains can arrive and depart without reverse gear head stations, from which all the tracks end with a bumper and train, in order to continue, it must turn around.
