"FIAT SU45 301Db" Once one of the best diesels in Poland. Today, a series of universal locomotives almost entirely converted into razor blades. FIAT because we are talking about it, your nickname just from the Fiat company, which was purchased with the license of the characteristic "bubbling" heart, i.e. the 2112SSF engine. For years, SU45 has been providing transport services on non-electrified lines, impeccably fixed in capital letters in the history of Polish railways, thus it cannot be missed in our projects.
