The CPR developed the first articulated locos in Canada in 1909 for helper service on the "Big Hill" between Field and Revelstoke BC. There were 6 0-6-6-0s in all, numbered 1950-55. The first 5 were introduced as compounds but no economy was found. The last, number 1955, was the first simple articulated. According to Chief Mechanical Officer H H Vaughn, the cylinders were placed head to head to shorten the dry pipe associated with the lead cylinders.
Another interesting feature is that each of the locos was superheated. The initial loco, number 1950, had a large square box mounted on top of the boiler above the cylinders to give access to a Horsey-Vaughn superheater, vertically mounted between a boiler divided into two. This was unsuccessful and teh loco was rebuilt with a more conventional superheater similar to other members of the class though it did retain the large box atop the boiler.
No particular economy in operation was found and they were very costly to maintain. As a result, they were rebuilt in 1917 to class R2 2-10-0s.
These were the only articulated locos ever attempted by the CPR who thereafter used rigid frame locos for climbing the Rockies.
I do not know the specific characteristics of a Kitson-Meyer but these locos have always been referred to as either compound or simple articulateds depending on which version was being referred to.
