In December 2004, SBB sold the locomotives Re 4/4 11110, 11117, 11119, 11123, 11137 and 11142 to BLS, which renumbered the locomotives as Re 420 501-506. A year later, SBB also took over locomotive 11107 and the prototypes Re 4/4 11102-11106, renumbering them 420 507-512. As the locomotives were urgently needed, they were painted in SBB's base colours for the first few years. Emblems and chrome lettering were all removed and replaced by simple silver decals. Gradually, the Re 420s were painted in the BLS corporate colours and also received the Omega logo, after the RM (Regional Mittellandbahn) was taken over. Re 420 505, formerly Re 4/4 11137, ran in green livery until 2009, when it was painted in the new BLS corporate colours.
