Some screenshots from Train Sim World - Great Western Express
This game add-on (set running out of London Paddington station) was released on Thursday 14th Sept 2017 and I've completed the tutorials and one scenario which was a high-speed 125mph run from Paddington to Reading station.
The screenshots show the incredible detail outside as well as inside the trains, and the great AI passengers that walk to exits and enter the trains.
