Top Speed is for " Talgo" trains which have little balance weights that shift to allow them to go faster on a " Said Curse" than a normal Amtrack car would safely go. Middle is speed for amtrak, bottom is of course freight speed limit.

I once asked an eminemt physicist "what is the safe level of radiation a human can take" The reply.
Find the level at which you can prove your government has poisoned you.
Anything below is safe. (Their experts will prove this absolutely).
Experts and safety, another oxymoron.
Memo to self, you must reduce your cynicism.
Always look on the bright side of life.
Thanks, I needed that.
Your welcome.

Wherever a government exists, s**t-for-brains planners exist. But back to the photo... The limits probably reflect the the highest safe speeds based on condition of the track and the center of gravity of the trains (Talgos tilt to compensate for leaning in the curves).

Now I understand, you have SFB planners in America as well. I thought we had a monopoly on them.

Railroad speed limits are based on logarithmic square roots of base 2 prime numbers. I can say no more lest my poor grasp of mathematics makes me look foolish.

Dave, 73 mph, how would they decide on such an odd, precise number.

You serious? Train speed limits? Why can't we pass term limits?
