Atlantic Coast Line 4-6-0 Class K-6 386 was built in 1906 by Burnham, Williams & Co. She had 64" drivers, 20 x 26 inch cylinders, boiler pressure of 185 lbs, and produced 25,623 lbs of tractive effort. She was a true mixed-traffic locomotive that was large enough to pull freight trains while able to work the branch line passenger service that didn't require high speeds. Some of these locomotives were still in service in the early 1950s. This image from my collection was taken May 15, 1939 at an unknown location.
