It would be nice (from a mapping stand point), but i suspect would be a pain in
the bum to complete.
If you look at a normal turn on a track_train path your going to have at least
3 entity - each placed in a bell curve, with each entity a 1/3 of the total
turn angle.
The only way your going to be able to simulate a turn, and speed is graph it
out, and then enter your trains path, if i was looking at making a 1:4 roller
coaster (or even a 1:8) i would use the default speed of 100 at the start, and
if i was going up hill, i would expect the speed to be 50% of that at the 1/2
way point, and 150% if going down hill.
Good luck!
