Railways are well developed in the Northern plains of India because; the North Indian plain is densely populated and has a highly developed agriculture and industry.
Large scale urbanization has also helped in the development of Railways. The North Indian plain is a plain leveled land which is the most favorable condition for the development of railways.
Railways developed more in the economically advanced areas where the need for the railway network is felt more. The huge agriculture produce from the grain market of the North Indian plain are transported by railways to different parts of the country.
