Prior to 1909. This was the world's largest locomotive at that time. The engine was built by the C.P.R. in 1893 with a shop No. 1194 and a road No. 624. At that time it had a 4-6-4 wheel arrangement with 19 X 22 inch cylinders and 62 inch driving wheels.

In 1905 this engine was renumbered 1950 and rebuilt into an articulated locomotive with a 0-6-6-0 wheel arrangement and 58 inch driving wheels, two high pressure 24-1/4 X 26 inch cylinders and two low pressure 34 X 26 inch cylinders as shown in the picture.

In 1909 it was renumbered No. 1995 and in 1912 to No. 5990.

This type of engine did not prove satisfactory at that time due to a number of reasons and in 1916 it was again rebuilt with only two 23-1/2 X 32 inch cylinders, 58 inch driving wheels and renumbered No. 5750.
