Check out the pre alpha in game footage from Train Sim World: CSX Heavy Haul! This is the next generation of Train Simulation built on the Unreal 4 platform.
For a limited time only, purchase Train Simulator 2017: Pioneers Edition and get access to the Train Sim World: CSX Heavy Haul Beta in December. Pioneers Edition is available now at http://store.steampowered.com/app/24010/
Please note: TS2017 and Train Sim World: CSX Heavy Haul are entirely separate products built on completely different technology foundations, and so we are unable to provide cross compatibility between the two.
