Examine the distributional pattern of railways in India.
1. North Indian Plains : This region has very dense network of railways from Amritsar to Howrah. This is a plain area which is very much suitable for the construction of railways. This area is highly densely populated and developed in agriculture and industry.
2. Peninsular Plateau : The whole area is hilly and plateau terrain which hinders the development of railways. The population density is also moderate.
3. Coastal Plains : There is a long route on the eastern coastal plains but such facilities are not found on the western coast.
4. Himalayan Region: The rugged terrain and hilly topography and backward economy are the factors which are responsible for sparse rail network in this region.
