Since the failure of Cisalpino, a joint venture between the Italian Trenitalia and the Swiss Federal Railways (SBB), the Pendolinos used for transalpine transport between Switzerland and Italy, on the Gotthard and Lötschberg axis routes, were split between Trenitalia (5 ETR 470 and 7 ETR 610) and SBB (4 ETR 470 and 7 ETR 610). The low reliability of the timetable and of the ETR 470 has led SBB and Trenitalia to always have a reserve train ready at each terminus of the Milan-Zürich route.
