"Hell on Wheels" Impossible Turn

"Hell on Wheels" is an AMC series about the building of the transcontinental railroad in 1865. It's heavy on personalities, vice, corruption, prejudice and pretty light on railroad building (unfortunately).

The week before last, I noticed this shot from the series:

Isn't that curve just a little sharp for a transcontinental railroad? I can't see anything negotiating that at more than about 3 mph.

http://en.wikipedia.org/wiki/Minimum_railway_curve_radius

Quote:
 

Minimum curve radii for railroads are governed by the speed operated and by the mechanical ability of the rolling stock to adjust to the curvature. In North America, equipment for unlimited interchange between railroad companys are built to accommodate 350-foot radius (16 degrees 26 minutes) or sharper, but normally 410-foot radius (14 degrees) is used as a minimum, as some freight cars are handled by special agreement between railroads that cannot take the sharper curvature. For handling of long freight trains, a minimum 717-foot radius (8 degrees) is preferred.

The sharpest curves tend to be on the narrowest of narrow gauge railways, where almost everything is proportionately smaller.[3][4]

The Confederate soldier was peculiar in that he was ever ready to fight, but never ready to submit to the routine duty and discipline of the camp or the march. The soldiers were determined to be soldiers after their own notions, and do their duty, for the love of it, as they thought best. Carlton McCarthy

I've been on that Welsh Highland Railway in Wales near Beddgelert (pronounced Bethgelert). It's an interesting trip :)
What do you mean "we", have you got a mouse in your pocket?
