Cumberland Railway & Coal 2-8-0 Locomotives in Canada


Class Details by Steve Llanso of Sweat House Media

Class 9 (Locobase 16306)

Data from Railway and Shipping World, New Series No. 50 (April 1902), p. 133. See also "Cumberland Railway and Coal Company" entry on the MemoryNS website at [link], last accessed 5 March 2017; and Ian McKay, "The Realm of Uncertainty: The Experience of Work in the Cumberland Coal Mines, 1873-1927", Acadiensis Blog entry 28 April 1916, pp. 3-57. last accessed 5 March 2017 at [link]. Works number was 25843 in May 1902.

R&SW's report of the #9's imminent arrival from Alco included many key details, but for some reason omitted all of the heating surface areas (tube, firebox, and grate).

Locobase 3930 shows an 1899 Richmond-built Consolidation design of which 75 were delivered to the Chesapeake & Ohio as their Class G-6. Many of the specifications were identical.

Even so, Locobase needed more confirmation before he could add the missing data to the specfications. So here, serving as estimates, are the heating surface areas of the G-6 class:

Evaporative heating surface area: 2,582 sq ft (260.69 sq m)

Firebox heating surface area : 239 sq ft ( 22.21 sq m)

Grate area : 35.5 sq ft ( 3.30 sq m)

The CR&C was incorporated in 1884 after it took over the Springhill and Parrsboro Coal and Railway Company, which had built a rail link from a mine at Springhill south to the port of Parrsboro on the Bay of Fundy. By the time the railway purchased its first Consolidation, the company had built up the line. In 1913, three years after Dominion Coal Company Ltd bought the railway, the line measured 32 miles long (51.5 km).
