Ken (?), who still has the Youtube channel "djstrains," and who is a CSX engineer in real life has pointed out more than once that real railroaders get paid to railroad...and he's right. If you could model everything (you can) to scale on your PC, then eight hours of running mileage would take eight hours, and most people would tire of doing it. It'd be much better to use the same sort of selective compression even in a virtual universe...and many would still get tired of it.

LOL, exactly. I've purchased pretty much every train sim there is. I play with them a bit, and then get bored. Often if I play them at all (rarely) I use them like a model railroad, letting the sim run the train and flying along in a virtual drone watching the show and enjoying the modeling work that went into it.
