I'm wanting to suggest to bring in one of europe's most famous sulzers, the 060 DA originating in Romania, however it was exported in many countries. This one aims to bring it to TSW4 in DB Red livery. Where would you find one in action? DB red livery exists in Romania operated by a German Branch of DB, DB Cargo Romania. A DA 1684 can be seen operating in Sibiu, a typical cargo train, photo by Desiro256. The Locomotive would operate anywhere in Romania, it just depends how much could be covered in one DLC basically. It's like a british class 37 but a little bit more growly.Would blend in nicely with all the German content current avalible no doubt!
