The '''Selkirk locomotives''' were 36 [[steam locomotive]]s of the [[2-10-4]] wheel arrangement built for [[Canadian Pacific Railway]] by [[Montreal Locomotive Works]], [[Montreal]] in [[Quebec]], Canada.
==History==
The first of these large engines, which had a 2-10-4 [[wheel arrangement]], was built in July 1929. Altogether, twenty were constructed before the end of this year bearing numbers 5900 to 5919. The [[Canadian Pacific Railway]]'s classification was '''T1a'''. These locomotives weighed {{convert|375|ST|lk=on}} fully loaded. They were the largest and most powerful locomotives in the British Empire. While most other 2-10-4s were named after the state of [[Texas]], these locomotives were named after the [[Selkirk Mountains|Selkirk range of mountains]] that they crossed, the (railway) summit of which was located just inside the western portal of the [[Connaught Tunnel]] beneath [[Rogers Pass (British Columbia)|Rogers Pass]].
Montreal Locomotive Works built another ten of these successful Selkirk locomotives during November and December 1938. The Canadian Pacific Railway assigned them '''T1b''' class. They were numbered from 5920 to 5929. Modifications led the T1b to be ten tons or tonnes lighter while increasing steam pressure from {{convert|275|to|285|psi|MPa|lk=on}}. A further six Selkirks, classed '''T1c''', were built by the Montreal Locomotive Works shop in 1949. They were the last [[standard gauge]] steam locomotives built in Canada for a Canadian railway. They were much the same as the T1b except for a few refinements, including two cross-compound air compressors to speed recharging of the air brake system.
Some small streamlining touches were not retained. The streamlined casing around the smokebox stack was now absent as was the teardrop shape of the classification lights. Also, the inside of the cabs were no longer lined/insulated in the same manner as the previous classes (previous classes had provided better cold-weather cab insulation and were more popular with engine crews). They were all equipped with [[booster engine|boosters]] (some shortly after being built) and all Selkirks (5900 through 5935) were built as oil burners. The tenders held {{convert|12000|impgal}} of water and {{convert|4100|impgal}} of fuel oil. They had to be equipped with two pairs of six-wheel trucks because the total tender [[mass|weight]] was {{convert|148|ST|LT t}}.
The first Selkirks, which come from the '''T1a''' class, had a heavier-looking, non-streamlined appearance which better exemplified the heavy steam-power look. Their original, as-delivered rear sand-domes were removed early in their service life. All of the later '''T1b''' and T1c-class locomotives were semi-streamlined and were painted with CPR [[Tuscan red]] panels along the sides of their running boards, beneath the cab windows and on the sides of the tenders with gold leaf (originally) border trim (which was later changed to a type of yellow similar to "duluxe gold"). Some of the original T1a-class Selkirks also received this paint scheme (but with narrower panels along the sides of the running boards that widened in the middle to carry the locomotive's road number).
All 36 Selkirk locomotives (5900 through 5935) were initially assigned to handle both freight as well as passenger trains between the major division points of [[Calgary]] and [[Revelstoke, British Columbia|Revelstoke]], a distance of {{convert|262|mi}}. They were also used for {{convert|23|mi}} in pusher service from Revelstoke west (uphill) to the wye at Taft, assisting the road engines of both freight as well as passenger trains up the steep grade to this location. The Laggan Subdivision covered the eastern portion of their assigned territory {{convert|137|mi}} and included the [[Field Hill]] and the [[Big Hill|Spiral Tunnels]] while the western portion of their primary, assigned territory consisted of the Mountain Subdivision which covered the remaining {{convert|126|mi}} and included [[Rogers Pass (British Columbia)|Rogers Pass]], the [[Connaught Tunnel]] and [[Stoney Creek Bridge]]. The grades encountered had a maximum of 2.2% (1 in 45), with curves of 12° or {{convert|480|ft}} radius. Rated at {{convert|78000|lbf|kN}} tractive effort, on the lesser grades they could haul {{convert|1050|ST|LT t}} unassisted and without the booster cut-in. The [[booster engine]] added an additional {{cvt|12000|lbf|kN}} of tractive effort up to a maximum speed of {{cvt|20|mph}}. Due to their extreme weight, they could not proceed west of Taft to Vancouver.
When diesels began operation between Calgary and Revelstoke in the early 1950s, the Selkirks were reassigned to work the [[Brooks, Alberta|Brooks]] and [[Maple Creek, Saskatchewan|Maple Creek]] subdivisions between Calgary and [[Swift Current]], Saskatchewan. They were also used to haul freight trains north of their new Alyth terminal (in Calgary) as far as [[Edmonton]]. At least some of the reassigned Selkirks received an "all black" (non-passenger) paint scheme without CPR Tuscan red panels and without grey or "blued" metal boiler-jackets; however, they still retained the yellow panel trim around the previous CPR Tuscan red (now black) panels (on those locomotives formerly painted with "outlined" panels). The last Selkirks (5930 through 5935) were taken out of service in 1959.
==Preservation==
All but two Selkirk locomotives class were scrapped, and both surviving classes are from the '''T1c''' class. None of the earlier '''T1a''' class or '''T1b''' class locomotives was preserved. The 5935 is preserved in the [[Canadian Railway Museum]], in [[Saint-Constant, Quebec]]. The 5931 (which was repainted and intentionally renumbered incorrectly as 5934 upon initial public display near downtown Calgary) is displayed at Heritage Park in [[Calgary]], Alberta.
