Since Dovetail has brought TS routes onto TSW2 lately why not this gem? CSX AC4400 and Dash 8 could have timetables established. Or maybe bring in the SD70 to the game. Would also like to pilot Amtrak's Silver Star service. Could also have Tri Rail as a future dlc add on for this route.
The TS2021 version has a CSX AC6000CW DLC which could be added as well. Perhaps a Brightline Siemens SCB40 Charger could also be added as DLC, as well as a CSX ET44AH or ST70AH (SD70ACe-T4) and MP15.
