Valdosta, Moultrie & Western 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 100 (Locobase 13562)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 45, p.171. Baldwin works numbers were 33718 in August 1909.

It's not clear to Locobase how this mid-1909 order wound up a dozen books away in volume 45 - housecleaning, perhaps? This was a small Ten-wheeler ordered by this 42-mile shortline that connected Valdosta with Moultrie in Georgia. It opened in 1910 and closed, to be torn up and recycled, in 1921.

100 was sold to the Georgia Northern when the VM & W was dismantled in 1921.


Class 101 (Locobase 13561)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 34, p.180. Baldwin works numbers were 33992 in November 1909 and 35469 in November 1911.

After purchasing the relatively small 100 (Locobase 13562), the VM & W went back to Baldwin very quickly for another, bigger Ten-wheeler. The 101 was a stock design that had entered service on several southeastern railroads. Two years later, the short line returned to the Philadelphia builder for another just like it.

When the ephemeral VM & W folded in 1921 after only 11 years of operation, the 101 went to the Live Oak, Perry & Gulf.
