Not offhand.
Been building a couple freelance in Surveyor to taste for GG1 and 100mph steamers - definitely not a just a couple of Sunday afternoons project.
At 100+ MPH baseboards go by quick.
Would imagine that at TGV, ICE, Shinkansen, and whatever China has named their new ones, speeds, 10 boards would take less than 2 minutes.
Didn't do any math, just a guess.
Anyway, they would eat up landscape quick.
Real Quick.
Probably not much point in doing sophisticated scenery between stations, too much processing power used that would end up being just a blur anyway.
Okay, back from looking at Manual - each little yellow square on a baseboard is 10 meters square; each baseboard is 72 squares x72 squares, so we'll call each baseboard 0.7 kilometers.
Baseboards are the large squares outlined on maps.
Lets say you're doing 100kph on the average down the back straight.
100kph/0.7k = roughly 140 baseboards per hour.
Is the game's "world" memory or whatever it's called, that big?
