Question for Copy 19
Author: tomstp

JB in the UP museum would there be technical data on the big boys such as degree of curvature the engine will take?

All that information is also in the hands of the UP Historical Society, as well as the Cheyenne Stem Shop, at least the Steam Shop used to have all that.

Thanks. I hope someone can answer the degree question.

I don't know. As I recall I did furnish some clearance information to the group in Texas regarding the 4018.

According to SteamLocomotive.Com , the minimum track curvature was 20 degrees.

Now what's the minimum curve radius on modern double track?

If you are talking degress of curvature that would be a maximum of 20 degrees (the higher the number, the sharper the curve.

I'm skeptical of the 20 degree figure. Using the chord definition of curvature, that works out to a curve radius of 287.94'.

I would be a bit cautious of anything over about 15 degrees. As with the 3900s, the tender won't handle sharp curves as well as the engine. A sharp curve would also need plenty of clearance for the articulation. Remember Clinchfield?
I'm sure this has been thoroughly discussed by the Engineering and Steam departments.
