Scenario designer allows you to use Peninsula Corridor's "GP38-2 UP + 12 Mixed Loaded" consist that contains 6 loaded centerbeam cars, which I believe are otherwise not available in any other scenario or timetable service. I've noticed this train is way too heavy for its size. I then found out that the game shows the weight of a single centerbeam as 228 tonnes (screenshot says 341.4 t, that's because I have that centerbeam coupled to GP38-2, which is 113.4 t), while it should be under 130 tonnes (286,000 lbs is the max gross rail load stenciled on the side). All units are metric, but the issue was the same using imperial units.
