Hey. A suggestion for new cargo containers design, if you were able to get the license of course, Tesco blue containers which also comes as “Less Co2 Rail” too. Be a good addition to British routes of course, and make it feel a lot more real in game as every1 knows Tesco in the uk.
For relevant locations you could get the Drax freight train from GBRF. With the special gold livery on the 66
