Data from AB&SOU 6 -1919 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.
The A&S Eight-wheeler was "used", but its provenance is unknown to Locobase; one source says that the 13 was rebuilt from A&S's 1888 Baldwin, road number 9. This engine may have originally been delivered to the Fort Worth & Denver.
A comparison with a very similar engine from another builder in the same year -- the Union Pacific's 780 class of ten locomotives delivered by Brooks -- shows an identically sized boiler and the same cylinder volume, but the Brooks engine had slightly larger grate, 1" taller drivers, and a pressure set at 150 psi. The A&S engine put 5 1/2 more tons (5,436 kg) on the drivers.
