Class Patrick (Locobase 802)

Railway & Locomotive Historical Society Bulletin #13 (1927) has a report by the railroad of this engine's performance.

An 1899 Locomotive History reproduced on http://www.livgenmi.com/1899LocomotiveHistory~41.htm gives the details (except for the boiler pressure) of this Planet type. The entry notes that the fireboxes in the class varied in depth from 3' 1 1/2" to 3' 3" deep giving heating surfaces of between 36.8 to 38.36 sq ft. The stack had two 1 1/2"-diameter blast pipes.

The other locomotives in the class were Concord, Nashua, Medford, and Suffolk.
