Class Details by Steve Llanso of Sweat House Media

Class 11 (Locobase 11135)

Data from Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 108-109.

Few of the skinny-gauge engines had 2 1/4" tubes, but this design did. It was a powerful mixed-traffic locomotive.
