The Re 460, popularly known as the Lok 2000, are a class of modern four-axle electric locomotives of Swiss Federal Railways (SBB CFF FFS), similar to the Re 465 of BLS.

Although designed as multipurpose locomotives, the Re 460 are now used only for hauling long-distance passenger trains in Switzerland (one service to Konstanz).

While originally designed as a multipurpose locomotive, they are now used for passenger services only, often in conjunction with the IC 2000 double-decker or EW IV [de] trainsets (often used to pull InterCity and InterRegio trains in the German and French language areas).

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.

The 46 Sr2 locomotives of VR (Finnish Railways) are closely based on the Re 460, as are the 22 NSB El 18 class used by Vy of Norway.
