Railway engineering
Railway engineering is the discipline of engineering which concerns the design, construction, operation, and maintenance of railways and rail transportation systems. It includes a wide range of engineering disciplines, including civil engineering, computer engineering, electrical engineering, mechanical engineering, industrial engineering and production engineering.
History
In the seventeenth and eighteenth century, the first railways were built for the horse-drawn trains of wagons in collieries and quarries, with the first materials consisting of stone slabs and timber baulks. However, the rails were weary with carrying heavier loads.During the Industrial Revolution, cast iron were added to the railway tracks to reduce the wear on the wooden baulks, which evolved further into iron edge rails, which enabled to flanged wheels' utility.
In the early nineteenth century, as the locomotives came into the picture, wrought iron rails and steel rails developed to support heavy axle loads without longitudinal timbers. With the advent of the railway, a need arose for specialized engineers capable of dealing with the unique problems associated with railway engineering. As the railways expanded and became a major part in logistics, more engineers became involved in the field, probably the most notable in Britain being Richard Trevithick, George Stephenson and Isambard Kingdom Brunel.
