What is the length of the standard railroad rail?

The standard American rail section has a length of 12 metres (39 feet). Some ore mining railroads in Western Australia employ rail weighing about 68 kg per metre (about 136 pounds per yard). One of the most important developments is the welding of standard rails into long lengths.

Because rails are made from steel, they expand as they get hotter, and can start to curve this is known as 'buckling'. Most of the network can operate when track temperatures heat up to 46°C – roughly equivalent to air temperature of around 30°C – but rails have been recorded at temperatures as high as 51°C.
