Temiskaming & Northern Ontario 4-6-0 Locomotives in Canada


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 11105)

Data from "Railway Equipment Notes ", The Railway and Shipping World (June 1903), pp. 188. CLC works numbers were 611-614.

Almost as an afterthought after its 25-locomotive order for the Canadian Northern (Locobase 10434), CLC produced another 4 for the T & NO to identical specifications. This included a relatively roomy Belpaire firebox. Locobase does not know if the 1906 order for the next 4 (works 689-692, road 105-108) were to the same design or to the slightly larger engines supplied in 1907-1908.

These small Ten-wheelers served the T & NO for about 15 years before being sold in 1917 to locomotive rebuilder Canadian Equipment Company. 101 and 104 were sold to Alberta Great Waterways in 1920 and later to Northern Alberta Railways in 1929. 102 and 103 went to work on the construction of the Welland Canal by Baldry Yerburgh & Hutchinson.


Class 115 (Locobase 11402)

Data from "Locomotive Building ", The Railroad Gazette, Vol XLII, (29 March 1907), p. 465 and Vol XLIII, No 8 (23 August 1907), p. 214. Works numbers were 841-846.

These were very similar to the 1903 engines supplied by the CLC (Locobase 11105), but had boiler tubes that measured 10 1/2" longer. Montreal Locomotive Works received the order reported in March and CLC the one outlined in August.
