Adirondack & St Lawrence 2-6-0 "Mogul" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 11725)

Data from Negative 3772, Degolyer Library collection of digitized Baldwin images, retrieved 26 October 2010 from http://digitalcollections.smu.edu/cdm4/item_viewer.php . Works numbers were 33127 in January 1908 and 37400 in December 1911.

The A&SL closed in 1921, leaving these two Moguls out of work. The 2 was bought by locomotive rebuilder/reseller Birmingham Rail & Locomotive, which in turn sold it to the National Cement Company. The NCC sold it back to BR & L, which then found a buyer in in Winsboro Granite Company in April 1931. WGC sold the 14 (as it was now numbered) to South Carolina's Rockton & Rion in 1934.

When that line went bankrupt almost 50 years later in 1981, Martin Marietta donated the rmotive power, rolling stock, and railroad to the South Carolina Railroad Museum. Two years later, the 14 was sold to the National Railway Historical Society.

3 took a more direct route to the De Grasse Paper Company.
