P1n subclass 2-8-2
Although officially designated as rebuilt locomotives the
5200's were in fact more new than old. They didn't even get their own
class, just subclass "n" of class P1. Starting with N2 class
2-8-0's (3600's and 3700's), new boilers, the heart of a steam locomotive,
were built along with the addition of mechanical stokers (NEVER say "automatic
stoker" to a fireman!), and application of an enclosed vestibule
cab. Much bigger tenders were applied as well, carrying 18 tons of coal
and 10,000 gallons of water. The engines themselves were already newer
from an earlier 1923-30 rebuild of the original 38-3900 N3 class 2-8-0's
with new frames, cylinders and motion. The 5200's continued to show the
original 1910-1914 dates most having been built by MLW (52), plus 8 CLC
and 5 by Canada Foundry. Note: "Engines" refers to the
two sets of cylinders and motion on each side comprising an independant
engine. It is possible for a locomotive to operate on only one side at
reduced power to clear the mainline in the event of a road failure. Cylinders:
22" diameter x 32" stroke. Drivers: 63" diameter. Boiler
pressure: 215 pounds per square inch. Tractive Effort: 45,000 pounds.
Initially, it had been proposed as far back as 1930 to build brand new
light 2-8-2's Class P3. This would have followed bigger Q1 Class 2-8-4's.
This was delayed first by the Great Depression and then by World War Two.
Eventually, the 2-8-4's were dropped (they would have been only slightly
more powerful than the latest P2 class 2-8-2's but, would have a larger
steam capacity because they were to utilize Royal Hudson-sized
boiler and firebox.) Instead, 65 N2 class 2-8-0's were rebuilt between
9/46 and 12/49 at the rate of about two a month by Angus Shops into P1n
class 2-8-2's. These were the last 2-8-2 Mikado types built. In
fact, all steam locomotive building came to an end in December 1949 with
the delivery of 5264 and the retirement of the now-legendary CPR Chief
of Motive Power and Rolling Stock: H.B. Bowen. Dieselization would soon
follow and be completed in just ten years.
P1n 5258 converted to oil for Western Lines. Unknown location.
