. It was seen as an advantage to use all Re 460, which had been designed for 200 km/h, for passenger service. The passenger division passed the Re 6/6 to SBB Cargo and bought 079–095 on 1 January 2003, 096–102 2004, and the rest 2005.

Advertising

Due in part to their large, mainly flat bodysides, Swiss Federal Railways were approached early on with requests for the Re 460 to be used as mobile advertising hoardings. Despite opposition from some quarters, the money that could be earned swayed the decision, and the first such locomotive, Re 460 015 was unveiled in 1994 in Agfa livery. Today no other loco type in Switzerland carries so many different liveries.
