The railway sector allows the transport of goods and people with the best energy efficient way. The smoothness of the tracks makes the movement more comfortable compared to other forms of transport by land. In generaI, for the same tons or number of passengers transported, a train requires 50 to 70% less energy than road transport and, since it unloads its weight on the ground through the sleepers, it distributes it better allowing greater weight per axle than any road transport. The unbalanced growth of road transport at the expense of rail transport has highlighted the need to create a competitive high-speed (high speed trains) rail system.
