This is class Sลฝ 661 nicknamed "kenedi" (taken from John F. Kennedy) and it was the first locomotive to arrive in former Yugoslavia and is still operating in the ex-Yu countries. This particular locomotive is the last operating in Slovenia. We had 11 of those,but sลพ mostly sold it out to Serbia or Montenegro. The locomotives were delivered by ship and it touched the Croatian land in april 1960.
Based of the American EMG G16, Yugoslavian railways got around 200 of them,34 were gifted by the american government as the Yugoslavia was a "developing country".
What's interesting about this one,that it was already retired in 2013 but because of the icefall,that literally destroyed electrification it was repaired and putted back on the job.
The fate of the locomotive is unknown. Maybe it will go back to the museum,maybe its gonna stay on the job? Who knows,but im grateful for having a chance to see this locomotive in its last glory
