Algoma Eastern 2-8-0 "Consolidation" Type Locomotives

Class C-1 / N4a (Locobase 4939)

Data from http://www.magma.ca/~morcomp/roster.html, which credits Dale Wilson's book Algoma Eastern Railway (Nickel Plate Rails, 1977). (Heating surface data from Dr. Jonathan Smith's http://www.math.iastate.edu/jdhsmith/term/slcaaer.htm -- 1 Feb 2004). Additional information from CP 2 - 1947 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Curiously, 52, which was delivered 5 months after Mogul M-1, has the next lowest builder's number (51182).

According to the 1947 book, 3952 - the lone C1 -- had a Vaughan & Horsey superheater.

After the CP took over the AER in 1930, these enginers were renumbered 3952-3956 and served until 1955.

Class C-2 / N4b (Locobase 4940)

Data from http://www.magma.ca/~morcomp/roster.html, which credits Dale Wilson's book Algoma Eastern Railway (Nickel Plate Rails, 1977). Additional information from CP 2 - 1947 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

These two engines (works numbers 1351-1352) slightly reduced the cylinder size compared to this line's C-1 Consolidation, but upped the boiler pressure.

After the CP took over the AER in 1930, 53 added 3900 to become 3953 and ran until 1956. 54 became 3954 and ran until 1958.

Class C-3 (Locobase 4941)

Considerably bigger than earlier AER Consolidations, these bore more heavily on the track as well. They showed higher superheat, but a smaller boiler in relation to cylinder volume. In 1930, when the Canadian Pacific leased the Algoma Eastern for 999 years, these two were renumbered 3955-56. Both carried on with the CP until 1957.
