What would anyone say is the most REALISTIC level for the track unevenness setting? Would like to know.
Thanks

There is no realistic level, as no two stretches of track are the same in prototype.
It also depends on what you think is visually appealing when riding the cab of a locomotive. I don't know if line uneveness is visible in the F5 passenger view.
The higher the line speed, the smoother the ride should be. So as not to make passengers nauseous and sick or damage shipped goods. Even coal gets spilled from the cars when they sway too violently. And for the reason I mention below, heavy duty coal haulers generally keep their track in tip top shape to prevent dynamic augmentation.
Generally, for well maintained mainline track with line speeds above 50 MpH I prefer a value in the 20-30 range.
Many railroads deferr maintenance when money is tight and reduce speed limits once the track starts to detoriate. Detoriation is a dynamic process that enhances itself. I.e. the track gets progressively worse and worse, and speed limits are ever lowered. So on those slow speed lines a value in the 40-60 range might be appropriate until the train derails at every other joint and the line has to be taken out of service.
It would be nice if route builders specifiy a few different track rules: primary main line - secondary main line - branch line - sidings - spurs, that get progressively worse.
Also a visual differentiation between those tracks would be nice: lighter rail - more rust - ties wider apart - less and lower grade ballast the further you stray from the mainline.
Unfortunately no track set comes with these variations as far as I know. Some route builders have made the difference themselves, like Tori Morgan's COARW. Here you clearly notice a visual difference, even though the current ScaleRail has been used for all tracks.
In our sim, one should also take the track geometry and the other parameters like superelevation into account.
Not all route builders lay perfect track with correct vertical and horizontal transitions with grading or curving the tracks. This leads to jolting and lurching both in the cabview and when you watch your train from the outside in 2,3 or 8 views. Superevelation without proper easements also leads to violent movements.

Thank you for the help!
