One of the first cab rides / führerstandsmitfahrt I watched on youtube was Führerstandsmitfahrt: Linke Rheinstrecke: Mainz-Köln by the youtuber/driver Reptifreak09. When DTG recently released Frankfurt-Koblenz I wanted to recreate this journey in TS2020.
I'm finally finished with part 1 of this project (from Mainz to Koblenz) and it will be available here on Rail-Sim when it has been approved by the moderators (hopefully). What I like about this approach is that you get to experience almost exactly (or as close as is possible in a simulator) what the real driver experienced on that journey. So the same train meets and the same signal aspects (if you drive as fast/slow as the driver does). It makes it a bit more interesting in my opinion compared to scenarios where the trains are based on the real timetable, since in the real world not all trains are on time.
Has anyone tried to do this for another train journey/video? I would highly recommend it! Although it can be a bit tricky sometimes because of the AI-controller in TS2020 so you might need to have the same train terminate in a portal and then have a new train finish the AI-journey etc (and some other "cheats" to make it look/behave like the real thing).
