Canadian Pacific Railway N-2-a, b, and c class locomotives were a class of 199 2-8-0 or Consolidation type locomotives built by Montreal Locomotive Works in 1912–1914. They were numbered 3600–3799 by CP and were used almost everywhere around the system.

Construction history

[edit]

The order for these engines came around 1912 when CP wanted bigger locomotives for their mainline. Their current engines were wearing out and were too small for the loads that were being hauled. The Montreal Locomotive Works was the one who did the job.

These locomotives were originally numbered 3800–3999. They were renumbered between 1920 and 1929 renumbered to the 3600 and 3700s. Most of the class were converted to oil-firing in the later years.

In the 1920s onward Canadian Pacific saw an increasing need for larger locomotives. Most of this class were relocated to either CP's Ogden or Montreal shops for a short time while 65 were converted to Class P1n 2-8-2 renumbered 5200–5264 in 1946 a larger boiler was added as well as a trailing truck and a new cab. They could haul several more thousand pounds than the original 2-8-0's could. Many of this class were converted, although not all, as many survived as 2-8-0's until the end of steam on CP.

Of the 199 locomotives that were built, only two remain in existence.
