Hey Dovetail, this would be a good addition to Sandpatch as a DLC. These SD70MACs are numbered 4700-4830 and they can be found in YN3, faded YN3, and YN3B. They have a K5LA, which I’m pretty sure Searchlight Simulations has the perfect sounds for it. Rolling stock that could come with it could be Tropicana and CryoTrans reefers.
I would also add the flat sided SD70MACs as well as CSX 4500 (was 700) is the Spirit of Cumberland locomotive.
