Looks like I'm a little rusty on those.
it's the chicane for the new sport, 'single track railroad grand prix'. they're really having a hard time firuring out passing in single track railroad races, though
Well the magic box said to put a stake here so....
Formulas:
Highway Curve (Arc Definition): Railroad Curve (Chord Definition):
1. DH = 5729.578 R 3. DR = 2 arcsine (50R)
2. R = 5729.578 DH 4. R = 50 sin (DR 2)
Tangent (both Railroad and Highway) Radius (both Railroad and Highway)
5. T = R tan ( ?2) 6. R = T tan ( ?2)
Good Luck. 🙂
Can't tell if those have a spiral component.
What? I staked it with my new 60k GPS system, and it cannot be wrong!

I thought the train zigged and zagged during our last trip!
"I shouldn't need all that math and stuff to get my license....If you can use the equipment, that is what you should be able to use on the test....."
Actually this is the physical manifestation of a "SHORT STATION"
What Equalities?

I said set out her vertical curve not as a horizontal curve!

How do the Railroads account for the coefficient of temperature with continuous steel tracks? I have always wondered that! Jp
