Canadian Pacific motive power today

Perhaps the clearest conception of the trend in locomotive design in this company may be drawn from a presentation of the existing classes in the order in which they have been built. A certain amount of standardization is to be detected after 1900 in the consistent application of new characteristics to several contemporary types. For instance, 58" and 63" drivers are used for freight and 70" and 75" drivers for passenger engines with few exceptions. Boiler pressures have increased regularly from 180 to 230, 250, 275 and 300 lbs. and many classes of engines have the same cylinder dimensions.

The oldest engine of the 1694 which were listed on January 1, 1941, is No. 105 a 4-4-0, the number, incidentally, being the fourth that it has borne. It 13 one of the remaining four of the A2 Class, built from 1882 to 1886, accompanied by Nos. 136, 144 and 158. With 63" drivers these engines run on the Eganville, Ont. and Chipman, N.B. subdivisions and are, apparently, the only power permitted on the light iron of these lines. The other two eight-wheelers left are of the A1 Class—strangely enough, as they were built in 1887, five years after the A2's. They are Nos. 29 and 30 and serve the Waltham run, out of Ottawa.

Two Moguls, 3011 and 3063, built in 1888, are listed; specially cut down for service through the Brockville Tunnel, they comprise the entire complement of this type, together with the 1912-built 3051, which was bought along with the rest of the Algoma Eastern, and running into Temiskaming.

356, a relic of the D3 ten-wheeler class was built in 1897 and was reported repaired at West Toronto a few months ago, but is now in the vicinity of Ottawa.

The oldest eight-coupled locomotives in existence are nine Ml's, the 3200 series Consolidations dated 1898 to 1900 and three Vl's, the 6800 series switchers rebuilt from them. The former c1ass are 'deckless' in that the engineer is unable to see the fireman; until last year they composed the freight power on the Esquimalt and Nanaimo. Tho M2's, of which eight remain, duplicated the Ml's the following year and were numbered directly after them.

The C.P.R. possesses almost one hundred small switchers, constructed since 1900; these are the 6100-6300 engines, U3, the last of only three classes. These were built until 1913; in 1912 a four wheel truck wass added and an 0-6-4 tank engine resulted. Two were made for special transfer service but only one remains, No. 5997, also running near Ottawa, which seems to have become the scene of the last miles of the oldest engines.

1901 saw the 2-8-0 enlarged into the 3300 series M3 type, but these too have largely disappeared, and are represented by ten machines, switching being the final disposition of some, a favourite practice on the C.P.R.

200 lb. boiler pressure was first used in 1902 on the D6's and E5's, freight and passenger 4-6-0's respectively. The D6's, with over 63" drivers, were turned out of shops in Germany, Scotland, and New York State, Numbered in the early 5001s, many of them serve the Dominion Atlantic, albeit minus their former red livery. The passenger engines, their high wheels giving them a comely line, bear numbers in the 2000's and 2100's and run out of Ottawa and Lindsay, some with inside steam chests and Stephenson valve gear.

1903 contributed many engines that are still useful, the only new class being the D9, numbered up to 597, which were the heaviest ten-wheelers ever used. Oil burning, 16 freight haulers remain from the original 39 built for the Rockies and later distributed over all western lines.

In 1904 the first of a great quantity of then heavy Consolidations were delivered from a variety of Canadian and American builders. These M4's are serialled 3400-3500, 124 of which roll their 58" drivers over all parts of Canada, and some have switching steps. Indeed, 20 of them dropped their engine trucks over Angus pits in 1929, took new drivers, and emerged as the V4 6920 switchers. One V2 0-8-0 also remains from that years production, and switches at 0ttawa.

The following year began the most spectacular orgy of locomotive building in the road's history. The first of the phenomenally successful D10's rolled out of Richmond shops; instantly popular, clean-limbed, big-boilered D1Ob's, c's and, by 1913 D10k's followed, and today, one of the almost 400 may be seen at practically any roundhouse on the road, numbered from 60O to 1100. Featured on the later models is a Walschaert gear hung inside the guide bars, they are favoured for their ease of handling and of repair.
