cp 4-6-2 "Pacific" Type Locomotives

Introduction

The CPR G-3h class locomotive were delivered by the Canadian Locomotive Company of Kingston, Ontario between August 1944 and April 1945. As with many modern locomotives on the CPR, to reduce costs of building and maintenance they were standardized with 75" drivers. Fitted with 22" x 30" cylinders and operating at 275 lbs steam pressure they produced over 45,000 lbs of tractive effort. These heavier Pacifics demonstrated the classic Bowen styling as noted by the sunken headlight, vestibule cab and wide running boards. Unlike earlier versions, the first half of this subclass were fitted with the Worthington Feedwater Heater, while the second half of the order utilized the classic Elesco Feedwater Heater. A new design for the era was the cast steel cradle used with the Vaughan trailing truck. This massive casting was integrated into the rear section of the locomotive frame, providing maximum space for the ash pan. Unfortunately, not a single example of this subclass was preserved as all were scrapped at the end of steam.

The CPR G-3g class locomotives were delivered by the Canadian Locomotive Company between January 1942 and February 1943. They too were standardized with 75" drivers. The 22" x 30" cylinders and operating steam pressure of 275 lbs produced over 45,000 lbs of tractive effort. Like the C-3h class, this class demonstrated the Bowen styling. No members of this subclass survive either.
