Here's another South Florida route yet to be created for Train Sim World. The route is over 70 miles. It would go from Miami to Magnolia Park in West Palm Beach. It would be set in the present day. The CSX rolling stock would include C30-7's, AC6000CW's, ES44ACH's, Dash 8-40CW's, SD70MAC's, SD80MAC's, SD60M's, SD60's, SD50's, SD40's, GP60's, Gensets, GP40's, GP38-2's, U36B's, AC4400CW's, B40-8's, MP15's, ET44AH's, ST70AH's, ES44AH's, ES44AC's, ES44DC's, SD40-2's, SD40-3's, and SW1500's with the same freight equipment like Train Simulator has. The Amtrak rolling stock would include B32BWH's, and P40's/P42's with the same passenger like Train Simulator equipment has. The Tri-Rail rolling stock would include F40PHL-2's and F40PH-2C's with Bombardier bi-level passenger coaches/cab cars and Hyundai Rotem passenger coaches/cab cars.
Personally I would just have it set in the present day and use the locomotives that I am more familiar with because it’s not really a historic Railroad as it still exists in 2021.
