cp 4-6-2 "Pacific" Type Locomotives
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
