Mobile & Ohio 2-6-0 "Mogul" Type Locomotives

Class E (Locobase 7358)

Data from AB&SOU 6 -1919 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Works number were 6401-6402, 6411, 6413.

This little railroad had little engines, like these Moguls, which were delivered to the M & O in October 1882. Unlike the others in the book, this engine's building date and original railroad are not recorded in the A & S's 1919 edition. One website that hosts A & S information -- http://www.trainweb.org/screamingeagle/roster_ab&so.html, accessed 22 Feb 2006 -- gives the building date as "1880s". With these clues and the Connelly list of all Baldwin locomotive works numbers, Locobase determined the above information for 6402. It was sold by the M & O by 1907 to the Abilene & Southern Railway in Texas.

Connelly's list reveals that there were 4 in the class. #62 (works 6401) was sold to the Alabama & Mississippi in 1909; that railroad sold the 62 to the Mississippi & Alabama (probably a corporate, rather than a physical, move) in September 1922. #65 (6411), by now renumbered 503, took that number to the De Kalb & Western (Sanoody Valley) by 1915 to help open the line in 1916, while 64 (6413) simply was scrapped.
