This very nice HO gauge locomotive by Roco is 43580 a SBB Am 4/4 diesel loco in red livery, it has running number 18463. 

The V200 (renamed V220) locomotives were introduced by DB in 1953. They hauled both passenger trains and freight, they were decommissioned in 1984 but went on to serve internationally in Saudi Arabia, Italy, Greece, Spain, France, Switzerland, Algeria, Albania and with some private operators in Germany.  The BR Class 42 and 43 Warship class are based on the V200. The Swiss SBB named the class Am 4/4 

The loco is in very good condition as you can see in the pictures, it is tested and runs with working lights, a complete external visual inspection has shown the overall condition is very good. It comes complete with its box. The box is in good if slightly shelf worn condition. 

Overall this is a really nice scale locomotive and would look fantastic 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. 

Note: I do recommend all locos are cleaned & serviced, as they have some age to them even if the quality looks at the highest level (fairly standard advice for all locos!).
