Columbus, Hocking Valley & Toledo / Virginia Air Line 2-6-0 "Mogul" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 13 (Locobase 9410)

Data from American Engineering & Railroad Journal, Vol LXVIII, #2 (February 1894), pp. 71-74. Works numbers were 1451 in April 1893 and 1489-1490 in November.

The AERJ explains that this design was one of five shown by Pittsburgh at the 1893 Columbian Exposition in Chicago. See Locobase 5845 for the Vandalia Line's very similar Ten-wheeler and a description of the "Pittsburgh system" of cross-compounding.


Class 3/E-5 (Locobase 7855)

Data from C&O 9-1936 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 32, p. 245. (Thanks to Chris Hohl for his 18 June 2015 email and spreadsheet pointing me to the Baldwin specifications page and VAL road numbers.) Works numbers were 32830-32831 in June 1908.

The Virginia Air Line was built to get around the loading-gauge limitations of many of the Blue Ridge tunnels on the C&O. Chartered in 1906 and opened in October 1908, the VAL linked the Piedmont subdivision with the Rivanna subdivision of the James River Line. Lindsay, Virginia was the junction at the Piedmont end and Strathmore joined the VAL and the Rivanna sub.

This pair of Moguls seem small to be carrying bigger loads than could fit through any tunnel; indeed, they were small 2-6-0s for their time, period. Baldwin's specs overestimated the adhesion and engine weights, a relatively rare outcome.

But they obviously served the mixed-traffic trains that made up the rest of the schedule. 427 left service in 1935, 428 in 1946.
