Locomotive 42 160 emerges from the ferry terminal of the port of Varna (Varna Feribotna) with a set of Russian freight cars. As well as the change of boggies to 1435-mm-gauge ones, these cars also require an additional car that is equipped with the standard coupling unit for Bulgaria on one side and the Russian equivalent on the other. This is the purpose of the first car behind the locomotive. 26 June 2007 Photo by Miroslav Georgiev (miroslav_sg@all.bg)
