Introduction
Legget, pp. 155-156: «Locomotive designs rarely cause widespread controversy but the last major design introduced by the CPR certainly did, two groups of semi-streamlined 4—4—4s intended for high-speed passenger service. Some had 80-in driving wheels and a boiler pressure of 300 psi. The five that were built in 1936 [Class F2a, which preceeded Class F1a: see next article] were seldom used to their full speed potential; their characteristic propensity for slipping prevented their use with heavy trains, but they remained in secondary service until 1958. Some thought them to be attractive-looking machines; others, the poorest-looking modern locomotives of the CPR, their unusual wheel arrangements and heavy trailing bogie giving them an almost unbalanced appearance.»
Buck, pp.167 & 169: «Semi-streamlining was applied with good effect to a new high-speed passenger locomotive with a 4—4—4 wheel arrangement. Named Jubilee, in honour of the fiftieth anniversary of transcontinental passenger service on the CPR, these diminutive locomotives were equipped with large, eighty-inch diameter driving wheels with low-friction roller bearings, and a boiler that operated at 300 psi, higher than any other CPR locomotive except the 8000.»
In this article, we present the class details as given in Lavallée's reproduction, p.17 of CPR's "Classification and Dimensions of Locomotives, January 1945". Moreover, we present images from various archives in their intrinsic dimensions. Note in passing that we could not find any photos for numbers 2021, 2926, 2927, 2928 and 2929.
