The rail profile is the cross sectional shape of a railway rail , perpendicular to its length. Early rails were made of wood, cast iron or wrought iron. All modern rails are hot rolled steel with a cross section profile approximate to an I-beam , but asymmetric about a horizontal axis however see grooved rail below. The head is profiled to resist wear and to give a good ride, and the foot profiled to suit the fixing system. Unlike some other uses of iron and steel, railway rails are subject to very high stresses and are made of very high quality steel.

Requirements for an Ideal Rail Section. The requirements for an ideal rail section are as follows. The rail should have the most economical section consistent with strength, stiffness, and durability. The requirements, as well as the main considerations, for the design of these rail components are as follows. Head : The head of the rail should have adequate depth to allow for vertical wear. The rail head should also be sufficiently wide so that not only is a wider running surface available, but also the rail has the desired lateral stiffness.

The permanent way sections are classified by IR according to the maximum speed or more precisely, the maximum speed proposed for the immediate future that the tracks are capable of supporting. In most cases this classification is more an indication of the priority of the route and IR's plans for it in the future, rather than an indication of the speeds allowed on it today. Also, some small stretches of a line may have much higher or lower allowed speeds than the classification of the line might indicate because of local conditions, mountainous terrain, sharp curves, etc. These are:.
