push the train in order not to overload the couplers. Locomotive 11638 was retired and scrapped in 1990 due to an accident. For the renumbering to the UIC-conforming new numbering scheme in 1992, only the still existing locomotives were considered, thus the 11638 got no new number any more. But the renumbering was never done consistently. During 2005, the UIC numbering scheme was reworked, and 620 001 (instead of 000) was defined to be the smallest number. To make things easy, the scrapped 11638 also got a new number, 620 038. About half a dozen locomotives bore the new numbers at the beginning of 2006. After two locomotives were tentatively equipped with radio remote control for pushing trains on the Gotthard line (such that the locomotive pushing at the end of the train may be controlled by the engineer at the front), about 30 locomotives were equipped with it in 2000. To make them administratively distinguishable, they got the new designation Ref 6/6. When SBB was divided into passenger services and freight, the first thirteen locomotives 11601–13 remained in the passenger division. On 1 January 2003 they were exchanged against Re 460. Now all remaining 88 locomotives are assigned to SBB Cargo. Due to the reassignment of the Re 460 to the passenger division, the Re 6/6 again dominate the freight traffic on the Gotthard line. The locomotives are assigned to the workshops Erstfeld, Bellinzona and Lausanne (Lausanne: 2000, today unknown), revisions are done at the main workshop at Bellinzona.
