Minimum radius curve for Emma Nevada with 144" wheelbase?

What would be the minimum radius curve for a locomotive like 36" gauge 2-6-0 Nevada Central #2 / Emma Nevada with a 144" wheelbase (measured from the centers of the flanged drivers)?

Would those on the forum familiar with narrow gauge operations please weigh in?

For comparison of NG minimum radius curves, based on Google Earth measurements:
Durango & Silverton has 220’ balloon track around roundhouse.
Huckleberry RR has 250’ turnaround on their main line west end running Baldwin 4-6-0 and K-27 2-8-2.
Colorado Railroad Museum has 260’ narrow gauge loop.
Knott’s Berry Farm has 190’ curve on main for 2-8-0.
US Gypsum has 250’ radius on wye for modern hoppers and diesels.

Specifically, would 200' minimum radius be sufficient for an operational loop for a 2-6-0 with 144" wheelbase? Why or why not? Thanks.
