what is it?

The Re 620, Re 6/6 in the old numbering scheme, are six-axle, electric locomotives of Swiss Federal Railways (SBB CFF FFS), which were acquired as a replacement for the Ae 6/6 for heavy services on the Gotthard Railway. They were produced between 1972 and 1980 and are the most modern of the so-called "Gotthard locomotives".
