[0002] Rail transport is a land transport method that uses two parallel rails to guide trains. Rail transport is one of the most efficient known land transport methods. Rails provide an extremely smooth and hard medium for the wheels of the train to roll on with minimal friction. This makes people on the train more comfortable and saves energy. If configured properly, rail transport can save 50% to 70% of the energy required to carry the same weight of passengers and cargo as road transport. In addition, rails can evenly distribute the weight of the train, greatly increasing the train's load-bearing capacity.
