I know that an X means a grade crossing. Speed limit signs & mile markers are fairly obvious.
I'm guessing a sign that has 30 above 35, or 45 above 40 means the top number is the max ascending speed and the lower number is the max descending speed?
I wonder what the W sign in this video (at about 1:30 on) means.
