This really nice HO gauge loco by Roco Professional is 63594 a Alstom Traxx F140 AC, Re485 electric locomotive in silver and green BLS cargo livery. It has running number Re 485 001-2.

The TRAXX F140 AC operates on AC overhead lines. They can work under both the 15 kV/16.7 Hz and the 25 kV/50 Hz AC systems. As built they are configured for future ETCS / ERTMS train control and safety systems. 20 units for Swiss private railway BLS AG (BLS Re485). The Swiss locomotives differ from the German versions in details such as pantographs (2 more, with smaller contacts for running under Swiss catenary (not because of tunnels)) and Switzerland specific safety systems in addition to the German systems. 

This example is in excellent condition (see pictures). I have not tested the loco but see no reason why it would not run as it is in very good condition. The box is bit shelf worn see pictures. Paperwork is included in the box

This locomotive is really just very nice and high quality. 

This loco would look great on a layout. 

Do please have a look at my other listings, I typically have various HO and OO locos on offer as well as an extensive range of imported N gauge locos and other items.
