As correctly pointed out by Mr.AA Sayed, station like Sealdah will attract a huge attention as Sealdah is the hub of suburban railways of Kolkata and is situtated at the heart of the city. People come from northern suburbs of the city to commute to southern parts and the central parts of the city for work as most of the offices are present in those areas.....and btw on a lighter note I think Bidhannagar road station does not fall under the constituency of Sudip Bandyopadhyay....so as Indians we don't expect politicians to waste their resources for doing something good to different constituency.
