Complex signaling systems are utilised if there are multiple route networks. Usually, trains are powered by an engine locomotive running on electricity or on diesel. Since this system runs on metal (usually steel) rails and wheels, it has an inherent benefit of lesser frictional resistance which helps attach more load in terms of wagons or carriages. It is one of the most important, commonly used and very cost effective modes of commuting and goods carriage over long, as well as, short distances. It is a means of transport, on vehicles which run on tracks (rails or railroads). Definition: Rail transport is also known as train transport.
