The regular freight trains between Mezdra and Sofia are not many, but they are usually quite long and some of them require twin power. In this case a mixed provision of tractive power provided by electric locomotive 45 173.2 and diesel locomotive 55 150.7. If you look closely to the right of 45 173 you will see the very last car of the train. Photo taken in Thompson. 26 June 2005
