Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p. See also the Mississippi Rails site at [] . Works number was 31843 in October 1907.
Locobase savors the name of one of the two termini on this 52-mile short line, which connected Nannahubba Bluff, Alabama with Healing Springs. The TV emerged in 1904 from the reorganization of the 3-foot-gauge Tombigbee & Northern. Alas, according to Mississippi Rails, it immediately abandoned the segment between Nannahubba Bluff and Calvert.
Its number 30 was bought at the same time and in the same purchase order as the Alabama, Tennessee & Northern's #10 (Locobase 13178). Cost was $9,800.
Five years later the 30 was reunited with the 10 when the AT & N consolidated its lines with the TV.
Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899). Works number was 2981 in June 1898.
Pocket Mogul for a light-rail narrow-gauge line that served the Sheffield, Penn. area.
(Two more Moguls were delivered to the TV as road 7 and 9. One was works number 3562, delivered in July 1900, the other was works number 3956, produced in September 1901. It's likely that they duplicated #6's data, but Locobase can't confirm.)
