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.
