French trains too tall for Italian tunnels: National operator faces ridicule after ordering multi-million-pound fleet that cannot operate its cross-Europe routes (http://www.dailymail.co.uk/news/art...ope-routes.html)

簡單來說，SNCF的新車因為車高比義大利境內鐵路隧道限高高了幾公厘，所以進不了義大利，目前只能跑法國國內路線。
SNCF去年也發生過新買的2000多輛車因為寬了1.2吋，結果必須花錢把1300多個車站的月台邊坡削窄。
