Tasks of rails
Without rails there is no railway system. Two rails build the base for the classic railways. However, more than two rails are possible when an electric rail is needed as well as when there are tracks with several rail tracks next to eachother. Rails are the main component that must bear the most load while in operation. Therefore rails must have specific properties.
