A Case Study of Nigerian railway, at the moment Nigerian railway is functioning at a barest minimal level due to the low operational speed in some cases, non ready availability and security threats. The population of Nigeria is over 200million therefore rail transport is an essential means of transportation that should be given attention. Most Nigerian roads are currently in bad states rendering movement of freights and passengers almost impassable. Rail transport ability to movement mass passengers and accommodate heavy volume of goods stand tall as a world wide advantage.
