Rutland 4-4-0 Locomotives in Canada


Class Details by Steve Llanso of Sweat House Media

Class 243/B9a (Locobase 15705)

Data from CP 1911-24 Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange. Works number was 5545 in March 1900.

This single Eight-wheeler was built for the Rutland, but soon sold to the Canadian Pacific. Compared to the Brooks engine ordered by the Bennington & Rutland in 1900 (see Locobase 15706), this locomotive had a longer wheelbase between truck wheels, straighter boiler, a few more tubes of (very slightly) shorter length.

Once on the CPR, the engine was renumbered several times. In February 1913, the cylinder was bushed down to an 18" bore.
