The 4-6-4 typos of ths Canadian Pacific originated in Pacific portion of their Majesties' tour, and as a result all vho demand during the late I92O3 for greater capacity in the the streamlined Hudsons soon became known as the Royal Hudsons, handling of main-line trains, such as the crack 6i-hour and were adorned with regal crowns at the front ends of their Toronto^Jontreal flyers "The Canadian" and "The Royal York", running board skirts. 285O and 2851 made the 3,224 mile trip which at this time were the fastest traine in the world, by from Quebec City to Vancouver, in the course of which they were virtue of their rune between Smiths Falls and Montreal, manned by 25 different engine crews. 285O was later exhibited 124,0 miles in 108 minutes, non-stop, at an average speed of at the New York World'a Fair of 1939. 68.8 miles per hour. In 1940, to assist with the heavy wartime traffic, a This search for improved motive power, conducted under further, and as events proved, final croup of Royal Hudsons the able leadership of ilr. C.

Saint John, M.B. While they were tried out on this route for a short time, it was considered inadvisable to assign them to As the construction of these first twenty Hudsons the eastern run regularly, due to bridge weight restrictions. coincided with the advent of a worldwide depression, no additional motive power was needed for several years. By As mentioned earlier, the Hudsons have been extremely 1937» however, conditions had improved sufficiently to make successful, and have given consistently efficient, reliable it possible to start replacing some of the obsolete power with service, especially during the difficult days of World War II. modem types, and in that year construction wae undertaken of Tlieir runs between i'/innipeg and Calgary. 84l miles each way. a further thirty Hudsons, the largest group of this tvoe to and between Toronto and Fort William. 711 miles, have been,' be added at one time. The new recruits form class H-lc for many years, among the longest rogularly-scheduled steam and are numbered from 2820 to 2849. By this time, stream• locomotive runs in the world. The standards of performance lining had become the vogue, and the H-lc's were given a and availability on these runs, the latter through the smooth jacket to enclose many of the usual external fittings, toughest operating territory east of the Rockies, have been together with a cowelled stack combined with smoke deflector, amazingly high, even though, in recent years, trains have recessed headlight, and solid pilot. Combined with the large grown far beyond the weights for which these locomotives vestibuled cab and massive twelve-wheeled tender, and finished were designed. in the C.P.R.'s fine passenger engine livery of glossy black, deep red, polished graphite, gold lettering and striping, white During the letter part of the recent war, there v/as ^ wheel tires, and plenty of bright metal, these streamlined talk of building mora Hudsons, but with the prospect of » Hudsons present a most attractive appearance, a happy blending diminishing traffic following the war, it was felt that a of modern design with the traditional appeal of the steam smaller machine would be more generally useful, and the 1200 locomotive. series of "General Service" Pacifies was built.
