Prince Edward Island 4-4-0 Locomotives in Canada

Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 15536)

Data from "Tank Locomotive for Prince Edward Island Railway", Engineering (8 November 1872), pp. 322-323.

The fuel (65 cubic feet of coke) and water for this little tank was supposed to be sufficient for a run of 40 miles (64 km). Unlike most British Isles engines of the same period, this locomotive had a full cab. The heavy plate frame' top plate ran uninterrupted from the front buffer to the rear buffer. Its cylinders were nestled in a near, but not fully, horizontal position under the plate on either side of the smoke box and over the bogie.
