What Are Train Rails Made Of?

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).

What Are Train Rails Made Of?

Rails are an essential part of any railroad track. They provide the stability needed to keep the trains moving forward, and they also support the weight of the train cars.

The rails are usually made from steel, but they can also be made from other materials such as iron, concrete, or even wood. The steel rails are made by first melting the steel in a furnace.

The molten steel is then poured into a mold that is the same shape as the rail. The mold is cooled, and the steel rail is removed. The steel rails are then heattreated to make them stronger.

The rails are then attached to the railroad ties with special spikes or bolts. The spikes or bolts go through the holes in the bottom of the rail and are driven into the tie.

The tie is then held in place by the weight of the rail. The rails are usually held together by special fasteners called rail joints. The rail joints allow the rails to expand and contract with the temperature changes.

They also allow the rails to move slightly so that they don‘t crack. The rails are also sometimes welded together. This is done by heating the two pieces of steel until they are hot enough to melt together. The molten steel is then allowed to cool
