====Introduction of the Talgo system====
In 1945, a Spanish engineer, [[Alejandro Goicoechea]], developed a streamlined, articulated train that was able to run on existing tracks at higher speeds than contemporary passenger trains. This was achieved by providing the locomotive and cars with a unique [[axle]] system that used one axle set per car end, connected by a Y-bar coupler. Amongst other advantages, the centre of mass was only half as high as usual.<ref>{{Google books |id=AyEDAAAAMBAJ |page=70 |title=Low Slung Train Travels Fast }} ''Popular Science'', February 1945, p. 70</ref> This system became famous under the name of [[Talgo]] (''Tren Articulado Ligero Goicoechea Oriol''), and for half a century was the main Spanish provider of high-speed trains.
