This view of C&O 2-10-4 No. 3018 was taken at Russell, Kentucky in September 1948. The photo, by an unidentified lensman, comes from the famous collection of the late Harold K. Vollrath, but this image was acquired from a now-discontinued Flickr site. The ABPR Archive contains the same image, uploaded in 2003 by Bud Laws. The Chesapeake & Ohio's T-1 2-10-4 was so successful that it spawned a legacy of steam designs. The Van Sweringen brothers' The Advisory Mechanical Committee produced a scaled-down version for the Nickel Plate's first class S 2-8-4s of 1934; this basic "Van Sweringen Berkshire" design was replicated in locomotives erected for five other railroads, including the C&O itself, the last examples being outshopped by Lima in 1949 as the Nickel Plate's class S-3. Meanwhile the C&O's "Allegheny" 2-6-6-6, built by Lima beginning in 1941, is said to be a lengthening of the T-1 design, articulated so that it could negotiate the curves of the railroad's hilly territory.
