伊比利亞軌距

伊比利亞軌距，寬1668毫米，主要用於西班牙和葡萄牙的鐵路。這是世界上使用中的第二寬的軌距，僅次於印度軌距。

西班牙和葡萄牙於1955年達成協議，採用1668毫米伊比利亞軌距。19世紀期間，西班牙和葡萄牙採用不同的軌距。西班牙起初以1672毫米軌距興建鐵路，而葡萄牙起初以標準軌興建鐵路，後來改用1664毫米軌距，而兩者軌距差異已經足夠互通。早期葡萄牙興建的標準軌鐵路後來改軌為伊比利亞軌距方便互通 - Assim, em 20 de Junho de 1860, funda a Companhia Real dos Caminhos de Ferro Portugueses que se propõe explorar as Linhas do Norte e do Leste e as linhas de que posteriormente obtivesse concessão. Thus, on June 20, 1860, founded the Society of Real Caminhos de Ferro Portugueses it proposes to exploit the lines of North and the East and the lines that subsequently obtain concession. De imediato a Companhia Real muda a bitola (1,44 metros) da linha já construída entre Lisboa e Asseca (68 Km.), passando-a para a bitola ibérica, com 1,67 metros, sem haver qualquer interrupção no serviço ferroviário. From immediate changes to the Company Real gauge (1.44 m) of the line already built between Lisbon and of Asseca (68 km), passing it to gauge the Iberian, with 1.67 metres, without any interruption in rail service.   。
