Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 20, pp 66 and 143 Works numbers were 14909-14910 in June 1896.
Relatively small for their wheel arrangement, these Moguls were modestly powered and lightweight. But the railway didn't impose heavy demands on them either, presenting a ruling grade just over 1%, curves swept quite gently in 1,000-metre radii. The Andino specified that these 2-6-0s had to be able haul 1,180 tons on the level at 30 km/h (19 mph).
