IMHO, of course, but the F4 HUD...............well, it's like a toy train thing. I shut it off, bring up the F3 and F5 HUD's. Second tab over on the F3 tells you the current speed limit, next speed limit and distance to that speed limit, your current speed, next signal distance and status of that signal, and track grade. Comes down to personal preference, but I'll stick with the old style. It works for me.
Bottom line, tho, is what Nick said. In RW, just like in the real world, you gotta learn the route. Period. Charts, all that good stuff, that's fine. But I would so much love to ride next to a seasoned engineer that's been railroading for years. They know every little dip in the track, where the coffee shops are, where the lunch trucks are. Oh, yeah, speed limits, too.
