108-475: The EMD SD90MAC is a model of 6,000  hp (4,470 kW) C-C diesel-electric locomotive produced by General Motors Electro-Motive Division (EMD). It is, with the SD80MAC , one of the largest single-engined locomotives produced by EMD and among the most powerful diesel-electric locomotives, surpassed only by the dual-engined DDA40X . The SD9043MAC is the 4,300  hp (3,210 kW) variant, using

216-788: A 999-year lease on the O&;Q on January 4, 1884. In 1895, it acquired a minority interest in the Toronto, Hamilton and Buffalo Railway , giving it a link to New York and the Northeast United States. The last spike in the CPR was driven on November 7, 1885, by one of its directors, Donald Smith. The first transcontinental passenger train departed from Montreal 's Dalhousie Station , at Berri Street and Notre Dame Street, at 8 pm on June 28, 1886, and arrived at Port Moody at noon on July 4. This train consisted of two baggage cars,

324-415: A ' brewery horse ' could produce 32,400 foot-pounds [43,929 J] per minute." James Watt and Matthew Boulton standardized that figure at 33,000 foot-pounds (44,742 J) per minute the next year. A common legend states that the unit was created when one of Watt's first customers, a brewer, specifically demanded an engine that would match a horse, and chose the strongest horse he had and driving it to

432-470: A 16-cylinder 710G engine instead of the H-engine , which was originally intended as a temporary alternative while EMD tried to solve the H-engine's issues. However, the accompanying upgrade program was never utilized by its customers. The SD90MAC's features include radial steering trucks with AC traction motors and an isolated safety cab which is mounted on shock absorbers to lessen vibrations in

540-867: A London-based hedge fund that owns 6% of the company. The creation of the Canadian Pacific Railway was undertaken as the National Dream by the Conservative government of John A. Macdonald , together with mining magnate Alexander Tilloch Galt . As a condition for joining the Canadian Confederation , British Columbia had insisted on a transport link to the East, with the rest of the Confederation. In 1873, Macdonald, among other high-ranking politicians, bribed in

648-489: A commitment extended to British Columbia when it entered Confederation in 1871; the CPR was Canada's first transcontinental railway . Primarily a freight railway, the CPR was for decades the only practical means of long-distance passenger transport in most regions of Canada and was instrumental in the colonization and development of Western Canada. The CPR became one of the largest and most powerful companies in Canada,

756-523: A corporate reorganization, each of the major operations, including its rail operations, were organized as separate subsidiaries. The name of the railway was changed to CP Rail, and the parent company changed its name to Canadian Pacific Limited in 1971. Its air, express, telecommunications, hotel and real estate holdings were spun off, and ownership of all of the companies transferred to Canadian Pacific Investments. The slogan was: "TO THE FOUR CORNERS OF THE WORLD". The company discarded its beaver logo, adopting

864-462: A day, paid in rice mats, and not including expenses, leaving barely anything to send home. They did the most dangerous construction jobs, such as working with explosives to clear tunnels through rock. The exact number of Chinese workers who died is unknown, but historians estimate the number is between 600 and 800. By 1883, railway construction was progressing rapidly, but the CPR was in danger of running out of funds. In response, on January 31, 1884,

972-476: A fleet of over a thousand Colonist cars , low-budget sleeper cars designed to transport immigrant families from eastern Canadian seaports to the west. During the first decade of the 20th century, the CPR continued to build more lines. In 1908, the CPR opened a line connecting Toronto with Sudbury . Several operational improvements were also made to the railway in Western Canada. On November 3, 1909,

1080-429: A group of engineers modified a dynometer to be able to measure how much horsepower a horse can produce. This horse was measured to 5.7 hp (4.3 kW). When torque T is in pound-foot units, rotational speed N is in rpm , the resulting power in horsepower is The constant 5252 is the rounded value of (33,000 ft⋅lbf/min)/(2π rad/rev). When torque T is in inch-pounds, The constant 63,025

1188-530: A healthy human can produce about 1.2 hp (0.89 kW) briefly (see orders of magnitude ) and sustain about 0.1 hp (0.075 kW) indefinitely; trained athletes can manage up to about 2.5 hp (1.9 kW) briefly and 0.35 hp (0.26 kW) for a period of several hours. The Jamaican sprinter Usain Bolt produced a maximum of 3.5 hp (2.6 kW) 0.89 seconds into his 9.58 second 100-metre (109.4 yd) sprint world record in 2009. In 2023

1296-501: A mail car, one second-class coach, two immigrant sleepers, two first-class coaches, two sleeping cars and a diner (several dining cars were used throughout the journey, as they were removed from the train during the night, with another one added the next morning). By that time, however, the CPR had decided to move its western terminus from Port Moody to Granville , which was renamed "Vancouver" later that year. The first official train destined for Vancouver arrived on May 23, 1887, although

1404-453: A million troops and passengers and four million tons of cargo. Twenty seven survived and returned to CPR. CPR also helped the war effort with money and jobs. CPR made loans and guarantees to the Allies of some $ 100 million. As a lasting tribute, CPR commissioned three statues and 23 memorial tablets to commemorate the efforts of those who fought and those who died in the war. After the war,

1512-635: A more aggressive construction policy; bonds were floated in London and called for tenders to complete sections of the railway in British Columbia. American contractor Andrew Onderdonk was selected, and his men began construction on May 15, 1880. In October 1880, a new consortium signed a contract with the Macdonald government, agreeing to build the railway for $ 25 million in credit and 25 million acres (100,000 km ) of land. In addition,

1620-788: A position it held as late as 1975. The company acquired two American lines in 2009: the Dakota, Minnesota and Eastern Railroad (DM&E) and the Iowa, Chicago and Eastern Railroad (IC&E). Also, the company owns the Indiana Harbor Belt Railroad , a Hammond, Indiana -based terminal railroad along with Conrail Shared Assets Operations . CPR purchased the Kansas City Southern Railway in December 2021 for US$ 31 billion . On April 14, 2023, KCS became

1728-679: A rebuild program to be converted into SD70ACUs. In 2021, Canadian Pacific purchased 40 more SD90MACs from the Union Pacific for further rebuilding into SD70ACU engines. In September 2014, Norfolk Southern purchased 100 4300 hp SD9043MACs from Union Pacific with the intent to rebuild them into SD70ACUs at the Juniata Shops . The last 4 SD90MACs were taken delivery by Norfolk Southern on October 3, 2015, running parallel to Western Avenue in Chicago , IL. In 2015, Cummins rebuilt

1836-789: A series of different owners since being spun off of the Canadian Pacific in 1995. The first operator was the Canadian American Railroad a division of Iron Road Railways . In 2002 the Montreal, Maine & Atlantic took over operations after CDAC declared bankruptcy. The Central, Maine and Quebec Railway started operations in 2014 after the MMA declared bankruptcy due to the Lac-Mégantic derailment. On this new acquisition, CP CEO Keith Creel remarked that this gives CP

1944-933: A significant port on the Atlantic Ocean. The CPR acquired the Quebec Central Railway on December 14, 1912. During the late 19th century, the railway undertook an ambitious program of hotel construction, building Glacier House in Glacier National Park , Mount Stephen House at Field, British Columbia , the Château Frontenac in Quebec City and the Banff Springs Hotel . By then, the CPR had competition from three other transcontinental lines, all of them money-losers. In 1919, these lines were consolidated into

2052-413: A single SD90MAC with its QSK95 engine, designed to meet Tier 4 emissions standards. Sygnet Rail Technologies and Brookville Equipment Corporation performed the conversion. The rebuild was designated HTL4200AC . The locomotive, numbered CECX No. 1919, had been Union Pacific No. 8559. Horsepower The term was adopted in the late 18th century by Scottish engineer James Watt to compare

2160-535: A true coast-to-coast network across Canada and an increased presence in New England. On June 4, 2020; Canadian Pacific bought the Central Maine and Quebec. On March 21, 2021, CP announced that it was planning to purchase the Kansas City Southern Railway (KCS) for US$ 29 billion. The US Surface Transportation Board (STB) would first have to approve the purchase, which was expected to be completed by

2268-624: A wholly owned subsidiary of CPR, and both CPR and its subsidiaries began doing business under the name of its parent company, CPKC . The CPR is publicly traded on both the Toronto Stock Exchange and the New York Stock Exchange under the ticker CP. Its U.S. headquarters are in Minneapolis . As of March 30, 2023, the largest shareholder of Canadian Pacific stock exchange is TCI Fund Management Limited ,

2376-510: Is a coefficient of theoretical brake horsepower and cylinder pressures during combustion. Nominal horsepower (nhp) is an early 19th-century rule of thumb used to estimate the power of steam engines. It assumed a steam pressure of 7 psi (48 kPa). Canadian Pacific The Canadian Pacific Railway ( French : Chemin de fer Canadien Pacifique ) ( reporting marks CP , CPAA , MILW , SOO ), also known simply as CPR or Canadian Pacific and formerly as CP Rail (1968–1996),

2484-420: Is also used in many places to symbolize brake horsepower. Drawbar power (dbp) is the power a railway locomotive has available to haul a train or an agricultural tractor to pull an implement. This is a measured figure rather than a calculated one. A special railway car called a dynamometer car coupled behind the locomotive keeps a continuous record of the drawbar pull exerted, and the speed. From these,

2592-463: Is equivalent to a boiler heat output of 33,469 Btu/h (9.809 kW). Present industrial practice is to define "boiler horsepower" as a boiler thermal output equal to 33,475 Btu/h (9.811 kW), which is very close to the original and revised definitions. Boiler horsepower is still used to measure boiler output in industrial boiler engineering in the US. Boiler horsepower is abbreviated BHP, which

2700-454: Is equivalent to a boiler heat output of 33,485 Btu/h (9.813 kW). A few years later in 1884, the ASME re-defined the boiler horsepower as the thermal output equal to the evaporation of 34.5 pounds per hour of water "from and at" 212 °F (100 °C). This considerably simplified boiler testing, and provided more accurate comparisons of the boilers at that time. This revised definition

2808-484: Is in psi, and flow rate is in US gallons per minute. Drilling rigs are powered mechanically by rotating the drill pipe from above. Hydraulic power is still needed though, as 1 500 to 5 000 W are required to push mud through the drill bit to clear waste rock. Additional hydraulic power may also be used to drive a down-hole mud motor to power directional drilling . When using SI units, the equation becomes coherent and there

2916-690: Is looking to fit 910-917 to the same specifications as 901-909. 916 is currently in the shop. On 1 August 2008, Union Pacific Railroad announced that it would be retiring 21 of the SD90MAC locomotives. Common parts will be used to maintain the railroad's 710-engined SD90MAC fleet. The 265H prime mover will be cut up or exported. The only part that is not reusable is the frame. These units, in the 8900 series will be removed from storage in Denver, and will be sent to East St. Louis , Ill., in small batches to be dismantled. As of 2019, Union Pacific still operates some of

3024-465: Is needed to pull a drawbar load of 2,025 pounds-force at 5 miles per hour? { P } h p = 2025 × 5 375 = 27. {\displaystyle \{P\}_{\mathrm {hp} }={\frac {2025\times 5}{375}}=27.} The constant 375 is because 1 hp = 375 lbf⋅mph. If other units are used, the constant is different. When using coherent SI units (watts, newtons, and metres per second), no constant

3132-507: Is needed, and the formula becomes P = Fv . This formula may also be used to calculate the power of a jet engine, using the speed of the jet and the thrust required to maintain that speed. Example: how much power is generated with a thrust of 4000 pounds at 400 miles per hour? { P } h p = 4000 × 400 375 = 4266.7. {\displaystyle \{P\}_{\mathrm {hp} }={\frac {4000\times 400}{375}}=4266.7.} This measure

3240-434: Is no dividing constant. where pressure is in pascals (Pa), and flow rate is in cubic metres per second (m ). Boiler horsepower is a boiler 's capacity to deliver steam to a steam engine and is not the same unit of power as the 550 ft lb/s definition. One boiler horsepower is equal to the thermal energy rate required to evaporate 34.5 pounds (15.6 kg) of fresh water at 212 °F (100 °C) in one hour. In

3348-513: Is ordinarily stated in watts or kilowatts. In the United States, the power output is stated in horsepower which, for this purpose, is defined as exactly 746 W. Hydraulic horsepower can represent the power available within hydraulic machinery , power through the down-hole nozzle of a drilling rig , or can be used to estimate the mechanical power needed to generate a known hydraulic flow rate. It may be calculated as where pressure

3456-743: Is the approximation of Assuming the third CGPM (1901, CR 70) definition of standard gravity , g n = 9.80665 m/s , is used to define the pound-force as well as the kilogram force, and the international avoirdupois pound (1959), one imperial horsepower is: Or given that 1 hp = 550 ft⋅lbf/s, 1 ft = 0.3048 m, 1 lbf ≈ 4.448 N, 1 J = 1 N⋅m, 1 W = 1 J/s: 1 hp ≈ 745.7 W The various units used to indicate this definition ( PS , KM , cv , hk , pk , k , ks and ch ) all translate to horse power in English. British manufacturers often intermix metric horsepower and mechanical horsepower depending on

3564-655: The Canada-U.S. Free Trade Agreement of 1989, which liberalized trade between the two nations, the CPR's expansion continued during the early 1990s: CP Rail gained full control of the Soo Line in 1990, adding the "System" to the former's name, and bought the Delaware and Hudson Railway in 1991. These two acquisitions gave CP Rail routes to the major American cities of Chicago (via the Soo Line and Milwaukee Road as part of its historically logical route) and New York City (via

3672-597: The Delaware and Hudson Railway in the northeastern United States. However, the new subsidiary, threatened with being sold off and free to innovate, quickly spun off money-losing track to short lines, instituted scheduled freight service, and produced an unexpected turn-around in profitability. On 1 January 2001 the StL&;H was formally amalgamated with the CP Rail system. In 2001, the CPR's parent company, Canadian Pacific Limited , spun off its five subsidiaries, including

3780-514: The Kettle Valley Railway in British Columbia, was built in response to the booming mining and smelting economy in southern British Columbia, and the tendency of the local geography to encourage and enable easier access from neighbouring US states than from Vancouver or the rest of Canada, which was viewed to be as much of a threat to national security as it was to the province's control of its own resources. The local passenger service

3888-677: The Lethbridge Viaduct over the Oldman River valley at Lethbridge , Alberta, was opened. It is 1,624 metres (5,328 feet) long and, at its maximum, 96 metres (315 feet) high, making it one of the longest railway bridges in Canada. In 1916, the CPR replaced its line through Rogers Pass , which was prone to avalanches (the most serious of which killed 62 men in 1910) with the Connaught Tunnel , an eight-kilometre-long (5-mile) tunnel under Mount Macdonald that was, at

3996-670: The New Brunswick Railway in 1891 for 991 years, and built the International Railway of Maine , connecting Montreal with Saint John, New Brunswick , in 1889. The connection with Saint John on the Atlantic coast made the CPR the first truly transcontinental railway company in Canada and permitted trans-Atlantic cargo and passenger services to continue year-round when sea ice in the Gulf of St. Lawrence closed

4104-801: The Pacific Scandal , granted contracts to the Canada Pacific Railway Company, which was unrelated to the current company, as opposed to the Inter-Ocean Railway Company, which was thought to have connections to the Northern Pacific Railway Company in the United States. After this scandal, the Conservatives were removed from power, and Alexander Mackenzie , the new Liberal prime minister, ordered construction of

4212-619: The Quebec, Montreal, Ottawa & Occidental Railway from the Quebec government and by creating a new railway company, the Ontario and Quebec Railway (O&Q). It also launched a fleet of Great Lakes ships to link its terminals. Through the O&Q, the CPR had effected purchases and long-term leases of several railways, and built a line between Perth, Ontario , and Toronto (completed on May 5, 1884) to connect these acquisitions. The CPR obtained

4320-794: The SD70MAC 's. These locomotives were informally designated SD9043MAC by railroads that purchased them with the option to re-engine them with 6,000  hp (4,470 kW) engines when they became available. This upgrade program, however, was never taken advantage of by SD90MAC buyers due to reliability issues with the newer engine. Over 400 SD90MAC locomotives fitted with the 4,300  hp (3,210 kW) 710 engine were built. In 1996, Electro-Motive Diesel entered full production on their 6,000  hp (4,470 kW), 16-cylinder H-engine, and all SD90MACs made from then on used that for its prime mover . Locomotives fitted with this engine are sometimes referred to as SD90MAC-H locomotives. Later versions of

The Canadian Pacific locomotives were part of an earlier order for 710-engine equipped SD90MAC locomotives that was still in production when Electro-Motive Diesel switched over to the H-engine. Electro-Motive Diesel also tried offering a lower-power version of the SD90MAC with a 12-cylinder engine called the SD89MAC , but none were produced other than

Other names for the metric horsepower are the Italian cavallo vapore (cv) , Dutch paardenkracht (pk) , the French cheval-vapeur (ch) , the Spanish caballo de vapor and Portuguese cavalo-vapor (cv) , the Russian лошадиная сила (л. с.) , the Swedish hästkraft (hk) , the Finnish hevosvoima (hv) ,

4644-571: The last spike was driven at Craigellachie, British Columbia . Four days earlier, the last spike of the Lake Superior section was driven in just west of Jackfish, Ontario . While the railway was completed four years after the original 1881 deadline, it was completed more than five years ahead of the new date of 1891 that Macdonald gave in 1881. In Eastern Canada, the CPR had created a network of lines reaching from Quebec City to St. Thomas, Ontario , by 1885 – mainly by buying

4752-603: The " Crow Rate " was permanently replaced by the Western Grain Transportation Act , which allowed the gradual increase of grain shipping prices. The Crowsnest Pass line opened on June 18, 1898, and followed a complicated route through the maze of valleys and passes in southern British Columbia, rejoining the original mainline at Hope after crossing the Cascade Mountains via Coquihalla Pass . The Southern Mainline, generally known as

4860-501: The 1926 Iowa State Fair , they reported that the peak power over a few seconds has been measured to be as high as 14.88 hp (11.10 kW) and also observed that for sustained activity, a work rate of about 1 hp (0.75 kW) per horse is consistent with agricultural advice from both the 19th and 20th centuries and also consistent with a work rate of about four times the basal rate expended by other vertebrates for sustained activity. When considering human-powered equipment ,

4968-486: The 1950s, the railway introduced new innovations in passenger service. In 1955, it introduced The Canadian , a new luxury transcontinental train. However, in the 1960s, the company started to pull out of passenger services, ending services on many of its branch lines. It also discontinued its secondary transcontinental train The Dominion in 1966, and in 1970, unsuccessfully applied to discontinue The Canadian . For

5076-616: The 9100-9160 series had been in long term storage in Winnipeg, Manitoba, for much of the 2010 decade. Three units, the 9129, 9133 and 9138, were scrapped in November 2012 due to errors in preparing them for long term storage. The entire fleet had been put up for sale in November 2012 and again in January 2013 with no offers being received. These units remained stored until the winter of 2018 when at first 30, then all 58 remaining units entered

5184-421: The CPR, into independent companies. In September 2007, CPR announced it was acquiring the Dakota, Minnesota and Eastern Railroad from London-based Electra Private Equity . The merger was completed as of October 31, 2008. Canadian Pacific Railway Ltd. trains resumed regular operations on June 1, 2012, after a nine-day strike by some 4,800 locomotive engineers, conductors and traffic controllers who walked off

5292-485: The CPR, to action. During this time the railway land grants were formalized. The Great Depression , which lasted from 1929 until 1939, hit many companies heavily. While the CPR was affected, it was not affected to the extent of its rival CNR because it, unlike the CNR, was debt-free. The CPR scaled back on some of its passenger and freight services and stopped issuing dividends to its shareholders after 1932. Hard times led to

5400-600: The Canadian government to build the railway, the CPR was granted 100,000 square kilometres (25 million acres). Canadian Pacific then began an intense campaign to bring immigrants to Canada; its agents operated in many overseas locations, where immigrants were often sold a package that included passage on a CP ship, travel on a CP train and land sold by the CP railway. Land was priced at $ 2.50 an acre and up but required cultivation. To transport immigrants, Canadian Pacific developed

5508-765: The D&;H). During the 1990s, both CP Rail and CN attempted unsuccessfully to buy out the eastern assets of the other, so as to permit further rationalization. In 1996, CP Rail moved its head office from Windsor Station in Montreal to Gulf Canada Square in Calgary and changed its name back to Canadian Pacific Railway. A new subsidiary company, the St. Lawrence and Hudson Railway , was created to operate its money-losing lines in eastern North America, covering Quebec , Southern and Eastern Ontario , trackage rights to Chicago, Illinois , (on Norfolk Southern lines from Detroit ) as well as

By the end of 1883, the railway had reached the Rocky Mountains, just 8 km (5.0 mi) east of Kicking Horse Pass. The treacherous 190 km (120 mi) of railway west of Fort William was completed by Purcell & Company, headed by "Canada's wealthiest and greatest railroad contractor," industrialist Hugh Ryan .

5832-420: The Federal government created Canadian National Railways (CNR, later CN) out of several bankrupt railways that fell into government hands during and after the war. CNR would become the main competitor to the CPR in Canada. In 1923, Henry Worth Thornton replaced David Blyth Hanna becoming the second president of the CNR, and his competition spurred Edward Wentworth Beatty , the first Canadian-born president of

5940-577: The H-engine approved at some later date. However, China recently announced an order for 300 JT56ACe locomotives, which also use the H-Engine as its prime mover. A portion of the locomotives will be assembled in kit form by China's own Dalian Locomotive Works . These units were reportedly capable of meeting the EPA's strict regulations and began delivery in the latter half of 2007. Due to reliability issues, FMG units 910 to 917 are stored and deemed not be used. They were purchased to be used as "slave" units, and they were more offline than they were in use. FMG

6048-511: The Kicking Horse River just after the Trans Canada Highway overpass. The three crew members on the lead locomotive were killed. The Canadian Pacific Police Service (CPPS) investigated the fatal derailment. It later came to light that, although Creel said that the RCMP "retain jurisdiction" over the investigation, the RCMP wrote that "it never had jurisdiction because the crash happened on CP property". On January 26, 2020, Canadian current affairs program The Fifth Estate broadcast an episode on

6156-411: The Quebec government added the CPR, along with lessor World Fuel Services (WFS), to the list of corporate entities from which it seeks reimbursement for the environmental cleanup of the Lac-Mégantic derailment. On July 15, the press reported that CP would appeal the legal order. On October 12, 2014, it was reported that Canadian Pacific had tried to enter into a merger with American railway CSX , but

6264-411: The SD90MAC-H feature a Phase II cab, with a new nose which offers higher visibility from the cab than the old nose. The SD90MAC-H did not prove popular with railroads and less than 70 were built, including Electro-Motive Diesel demonstrator units. Since the SD90MAC-H had such a large prime mover, it didn't offer the same operational flexibility as smaller units, limiting its possible customer base to only

6372-483: The Ukrainian кінська сила (к. с.) , the Romanian cal-putere (CP) , and the German Pferdestärke (PS) . In the 19th century, revolutionary-era France had its own unit used to replace the cheval vapeur (horsepower); based on a 100 kgf ⋅m/s standard, it was called the poncelet and was abbreviated p . Tax or fiscal horsepower is a non-linear rating of a motor vehicle for tax purposes. Tax horsepower ratings were originally more or less directly related to

Its rail network also served Minneapolis–St. Paul , Milwaukee , Detroit , Chicago , and Albany, New York , in the United States. The railway was first built between eastern Canada and British Columbia between 1875 and 1885 (connecting with Ottawa Valley and Georgian Bay area lines built earlier), fulfilling

6588-570: The cab. The SD90MAC, like the SD80MAC, SD70ACe , and SD70M-2 , has a wide radiator section, nearly the entire width of the locomotive, which along with their size makes them easy to spot. As of 2019, some SD90MACs are still in service on the Union Pacific. Norfolk Southern had rostered 110 SD90MAC locomotives purchased or traded from Union Pacific or the CIT Group respectively, that have now all been rebuilt as EMD SD70ACU locomotives. Canadian Pacific has also opted to convert their small fleet of long-stored SD90MACs into SD70ACUs as well. The SD90MAC

Where railways had previously provided almost universal freight and passenger services, cars, trucks and airplanes started to take traffic away from railways. This naturally helped the CPR's air and trucking operations, and the railway's freight operations continued to thrive hauling resource traffic and bulk commodities. However, passenger trains quickly became unprofitable. During

Later that year, the Second World War began. As it had done in World War I, the CPR devoted much of its resources to the war effort. It retooled its Angus Shops in Montreal to produce Valentine tanks and other armoured vehicles, and transported troops and resources across

7020-412: The creation of new political parties such as the Social Credit movement and the Cooperative Commonwealth Federation , as well as popular protest in the form of the On-to-Ottawa Trek . One highlight of the late 1930s, both for the railway and for Canada, was the visit of King George VI and Queen Elizabeth during their 1939 royal tour of Canada , the first time that the reigning monarch had visited

7128-462: The derailment, and the next day the Canadian Transportation Safety Board (TSB) called for the RCMP to investigate as lead investigator Don Crawford said, "There is enough to suspect there's negligence here and it needs to be investigated by the proper authority". On February 4, 2020, the TSB demoted its lead investigator in the crash probe after his superiors decided these comments were "completely inappropriate". The TSB stated that it "does not share

7236-447: The derailment. Part of the compromise was to accept GO Transit commuter rail service along the Galt Subdivision corridor up to Milton, Ontario . Limited trains ran along the Milton line on weekdays only. Expansions to Cambridge, Ontario may be coming in the future. In 1984, CP Rail commenced construction of the Mount Macdonald Tunnel to augment the Connaught Tunnel under the Selkirk Mountains . The first revenue train passed through

7344-576: The early days of steam use, the boiler horsepower was roughly comparable to the horsepower of engines fed by the boiler. The term "boiler horsepower" was originally developed at the Philadelphia Centennial Exhibition in 1876, where the best steam engines of that period were tested. The average steam consumption of those engines (per output horsepower) was determined to be the evaporation of 30 pounds (14 kg) of water per hour, based on feed water at 100 °F (38 °C), and saturated steam generated at 70 psi (480 kPa). This original definition

7452-424: The engine's bore size, number of cylinders, and a (now archaic) presumption of engine efficiency. As new engines were designed with ever-increasing efficiency, it was no longer a useful measure, but was kept in use by UK regulations, which used the rating for tax purposes . The United Kingdom was not the only country that used the RAC rating; many states in Australia used RAC hp to determine taxation. The RAC formula

7560-499: The engine. The situation persisted for several generations of four- and six-cylinder British engines: For example, Jaguar's 3.4-litre XK engine of the 1950s had six cylinders with a bore of 83 mm (3.27 in) and a stroke of 106 mm (4.17 in), where most American automakers had long since moved to oversquare (large bore, short stroke) V8 engines . See, for example, the early Chrysler Hemi engine . The power of an engine may be measured or estimated at several points in

7668-411: The first spike was driven into a sunken railway tie. That was the point where the Canada Central Railway (CCR) extension ended. The CCR started in Brockville and extended to Pembroke. It then followed a westward route along the Ottawa River and continued to Mattawa at the confluence of the Mattawa and Ottawa rivers. It then proceeded to Bonfield. It was presumed that the railway would travel through

7776-515: The government defrayed surveying costs and exempted the railway from property taxes for 20 years. A beaver was chosen as the railway's logo in honour of Donald Smith, 1st Baron Strathcona and Mount Royal , who had risen from factor to governor of the Hudson's Bay Company over a lengthy career in the beaver fur trade. Building the railway took over four years. The Canadian Pacific Railway began its westward expansion from Bonfield, Ontario , where

7884-726: The government passed the Railway Relief Bill, providing a further $ 22.5 million in loans to the CPR. The bill received royal assent on March 6, 1884. In March 1885, the North-West Rebellion broke out in the District of Saskatchewan . Van Horne, in Ottawa at the time, suggested to the government that the CPR could transport troops to Qu'Appelle in the District of Assiniboia in 10 days. Some sections of track were incomplete or had not been used before, but

7992-647: The government-owned Canadian National Railways . During the First World War, CPR put the entire resources of the "world's greatest travel system" at the disposal of the British Empire , not only trains and tracks, but also its ships, shops, hotels, telegraphs and, above all, its people. Aiding the war effort meant transporting and billeting troops; building and supplying arms and munitions; arming, lending and selling ships. Fifty-two CPR ships were pressed into service during World War I, carrying more than

8100-489: The horse could pull with a force of 180 pounds-force (800 N). So: Engineering in History recounts that John Smeaton initially estimated that a horse could produce 22,916 foot-pounds (31,070 J) per minute. John Desaguliers had previously suggested 44,000 foot-pounds (59,656 J) per minute, and Thomas Tredgold suggested 27,500 foot-pounds (37,285 J) per minute. "Watt found by experiment in 1782 that

8208-429: The job on May 23, stalling Canadian freight traffic and costing the economy an estimated CA$ 80 million ( US$ 77 million ). The strike ended with a government back-to-work bill forcing both sides to come to a binding agreement . On July 6, 2013, a unit train of crude oil which CP had subcontracted to short-line operator Montreal, Maine and Atlantic Railway derailed in Lac-Mégantic , killing 47. On August 14, 2013,

8316-465: The largest railroads. Also, since the H-engine was a new design, it hadn't reached the same level of reliability as EMD's previous engine. The low reliability on such a large engine was an especially bad combination since the loss of one engine in a train meant the loss of a larger percentage of pulling power than had a smaller engine failed. In the end, the SD90MAC-H was only delivered to two railroads,

8424-676: The left bank of the Kaministiquia River in the District of Thunder Bay, about four miles upriver from Fort William. Once completed in 1882 with a last spike at Feist Lake, near Vermilion Bay, Ontario , the line was turned over to the newly-minted private Canadian Pacific Railway company. In 1883, the first wheat shipment from Manitoba was transported over this line to the Lakehead (Fort William and Port Arthur) on Lake Superior. Macdonald would later return as prime minister and adopt

8532-454: The limit. In that legend, Watt accepted the challenge and built a machine that was actually even stronger than the figure achieved by the brewer, and the output of that machine became the horsepower. In 1993, R. D. Stevenson and R. J. Wassersug published correspondence in Nature summarizing measurements and calculations of peak and sustained work rates of a horse. Citing measurements made at

8640-597: The line had already been in use for three months. The CPR quickly became profitable, and all loans from the federal government were repaid years ahead of time. In 1888, a branch line was opened between Sudbury and Sault Ste. Marie where the CPR connected with the American railway system and its own steamships. That same year, work was started on a line from London, Ontario , to the Canada–US border at Windsor, Ontario . That line opened on June 12, 1890. The CPR also leased

8748-456: The middle of 2022. However, a competing cash and stock offer was later made by Canadian National Railway (CN) on April 20 at $ 33.7 billion. On 13 May, KCS announced that they planned to accept the merger offer from CN, but would give CP until May 21 to come up with a higher bid. On May 21, KCS and CN agreed to a merger. However, CN's merger attempt was blocked by a STB ruling in August that

8856-492: The new Multimark (which, when mirrored by an adjacent "multi-mark" creates a diamond appearance on a globe) that was used – with a different colour background – for each of its operations. On November 10, 1979, a derailment of a hazardous materials train in Mississauga, Ontario , led to the evacuation of 200,000 people; there were no fatalities. Mississauga Mayor Hazel McCallion threatened to sue Canadian Pacific for

8964-460: The next eight years, it continued to apply to discontinue the service, and service on The Canadian declined markedly. On October 29, 1978, CP Rail transferred its passenger services to Via Rail , a new federal Crown corporation that is responsible for managing all intercity passenger service formerly handled by both CP Rail and CN. Via eventually took almost all of its passenger trains, including The Canadian , off CP's lines. In 1968, as part of

9072-512: The origin of the engine in question. DIN 66036 defines one metric horsepower as the power to raise a mass of 75 kilograms against the Earth's gravitational force over a distance of one metre in one second: 75 kg × 9.80665 m/s × 1 m / 1 s = 75  kgf ⋅m/s = 1 PS. This is equivalent to 735.49875 W, or 98.6% of an imperial horsepower. In 1972, the PS was replaced by

9180-529: The output of steam engines with the power of draft horses . It was later expanded to include the output power of other power-generating machinery such as piston engines , turbines , and electric motors . The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010,

9288-512: The port of Montreal during the winter months. By 1896, competition with the Great Northern Railway for traffic in southern British Columbia forced the CPR to construct a second line across the province, south of the original line. Van Horne, now president of the CPR, asked for government aid, and the government agreed to provide around $ 3.6 million to construct a railway from Lethbridge, Alberta , through Crowsnest Pass to

9396-670: The power generated can be calculated. To determine the maximum power available, a controllable load is required; it is normally a second locomotive with its brakes applied, in addition to a static load. If the drawbar force ( F ) is measured in pounds-force (lbf) and speed ( v ) is measured in miles per hour (mph), then the drawbar power ( P ) in horsepower (hp) is { P } h p = { F } l b f { v } m p h 375 . {\displaystyle \{P\}_{\mathrm {hp} }={\frac {\{F\}_{\mathrm {lbf} }\{v\}_{\mathrm {mph} }}{375}}.} Example: How much power

9504-573: The prototype. Prime mover (EMD 710): Prime mover (EMD 265): Traction motors: Performance (parenthesis indicate H-Engine equipped specifications): Canadian Pacific CEFX EMLX Indiana Rail Road Norfolk Southern Union Pacific : Fortescue Metals Group As of January 2005, the SD90MAC is no longer in production due to the Environmental Protection Agency 's Tier 2 locomotive emission regulations, although EMD had planned to be able to get

9612-633: The railway under the supervision of the Department of Public Works. Enabled by the CPR Act of 1874, work began in 1875 on the Lake Superior to Manitoba section of the CPR. The ceremonial sod-turning at Westfort on June 1, 1875, was prominently reported in the June 10 edition of the Toronto Globe . It noted that a crowd of "upwards of 500 ladies and gentlemen" gathered to celebrate the event on

9720-544: The railway. Many were European immigrants. An unknown number of Stoney Nakoda also assisted in track laying and construction work in the Kicking Horse Pass region. In British Columbia, government contractors eventually hired 17,000 workers from China, known as " coolies ". After 2 + 1 ⁄ 2 months of hard labour, they could net as little as $ 16 ($ 485 in 2023 adjusted for inflation) Chinese labourers in British Columbia made only between 75 cents and $ 1.25

9828-474: The remaining SD9043MACs, which sport new numbers and UP wings on the cab. These units take the original road numbers of the Union Pacific's original SD40-2 fleet. Canadian Pacific's SD90MAC-H locomotives 9300-9303 (listed as SD90MAC6000s) were up for tendered sale in 2009. The bidding ended 31 March 2010. While they were originally thought to be shipped overseas, they were eventually moved to Quebec for scrapping. Canadian Pacific's SD90MAC locomotives, numbered in

9936-418: The renowned railway executive William Cornelius Van Horne to oversee construction. Van Horne stated that he would have 800 km (500 mi) of main line built in 1882. Floods delayed the start of the construction season, but over 672 km (418 mi) of main line, as well as sidings and branch lines, were built that year. The Thunder Bay branch (west from Fort William ) was completed in June 1882 by

10044-814: The rich "fertile belt" of the North Saskatchewan River Valley and cross the Rocky Mountains via the Yellowhead Pass . However, a more southerly route across the arid Palliser's Triangle in Saskatchewan and via Kicking Horse Pass and down the Field Hill to the Rocky Mountain Trench was chosen. In 1881, construction progressed at a pace too slow for the railway's officials who, in 1882, hired

10152-408: The savings in coal from the older Newcomen steam engines . This royalty scheme did not work with customers who did not have existing steam engines but used horses instead. Watt determined that a horse could turn a mill wheel 144 times in an hour (or 2.4 times a minute). The wheel was 12 feet (3.7 m) in radius; therefore, the horse travelled 2.4 × 2π × 12 feet in one minute. Watt judged that

10260-423: The size of the engine; but as of 2000, many countries changed over to systems based on CO 2 emissions, so are not directly comparable to older ratings. The Citroën 2CV is named for its French fiscal horsepower rating, "deux chevaux" (2CV). Nameplates on electrical motors show their power output, not the power input (the power delivered at the shaft, not the power consumed to drive the motor). This power output

10368-476: The south shore of Kootenay Lake , in exchange for the CPR agreeing to reduce freight rates in perpetuity for key commodities shipped in Western Canada. The controversial Crowsnest Pass Agreement effectively locked the eastbound rate on grain products and westbound rates on certain "settlers' effects" at the 1897 level. Although temporarily suspended during the First World War , it was not until 1983 that

10476-623: The time of its opening, the longest railway tunnel in the Western Hemisphere . On January 21, 1910, a passenger train derailed on the CPR line at the Spanish River bridge at Nairn, Ontario (near Sudbury ), killing at least 43. On January 3, 1912, the CPR acquired the Dominion Atlantic Railway , a railway that ran in western Nova Scotia . This acquisition gave the CPR a connection to Halifax ,

10584-502: The transmission of the power from its generation to its application. A number of names are used for the power developed at various stages in this process, but none is a clear indicator of either the measurement system or definition used. In general: All the above assumes that no power inflation factors have been applied to any of the readings. Engine designers use expressions other than horsepower to denote objective targets or performance, such as brake mean effective pressure (BMEP). This

10692-458: The trip to Winnipeg was made in nine days and the rebellion quickly suppressed. Controversially, the government subsequently reorganized the CPR's debt and provided a further $ 5 million loan. This money was desperately needed by the CPR. Even with Van Horne's support with moving troops to Qu'Appelle, the government still delayed in giving its support to CPR, due to Macdonald pressuring George Stephen for additional benefits. On November 7, 1885,

10800-604: The tunnel in 1988. At 14.7 km (nine miles), it is the longest tunnel in the Americas. During the 1980s, the Soo Line Railroad , in which CP Rail still owned a controlling interest, underwent several changes. It acquired the Minneapolis, Northfield and Southern Railway in 1982. Then on February 21, 1985, the Soo Line obtained a controlling interest in the bankrupt Milwaukee Road , merging it into its system on January 1, 1986. Also in 1980, Canadian Pacific bought out

10908-518: The use of horsepower in the EU is permitted only as a supplementary unit. The development of the steam engine provided a reason to compare the output of horses with that of the engines that could replace them. In 1702, Thomas Savery wrote in The Miner's Friend : The idea was later used by James Watt to help market his improved steam engine. He had previously agreed to take royalties of one-third of

11016-705: The view of the lead safety investigator". The CPPS say they did a thorough investigation into the actions of the crew, which is now closed and resulted in no charges, while the Alberta Federation of Labour and the Teamsters Canada Rail Conference called for an independent police probe. On November 20, 2019, it was announced that Canadian Pacific would purchase the Central Maine and Quebec Railway from Fortress Transportation and Infrastructure Investors . The line has had

11124-483: Was a Canadian Class I railway incorporated in 1881. The railway is owned by Canadian Pacific Kansas City Limited , known until 2023 as Canadian Pacific Railway Limited , which began operations as legal owner in a corporate restructuring in 2001. The railway is headquartered in Calgary , Alberta. In 2023, the railway owned approximately 20,100 kilometres (12,500 mi) of track in seven provinces of Canada and into

11232-595: Was instituted by the Royal Automobile Club and was used to denote the power of early 20th-century British cars. Many cars took their names from this figure (hence the Austin Seven and Riley Nine), while others had names such as "40/50 hp", which indicated the RAC figure followed by the true measured power. Taxable horsepower does not reflect developed horsepower; rather, it is a calculated figure based on

11340-489: Was introduced in 1995, along with the SD80MAC locomotives. The SD90MAC was designed to utilize the new 16-cylinder H-engine , while the SD80MAC was designed to use the 20-cylinder version of the existing 710G engine. However, technical problems with the 6,000 horsepower (4,500 kW) engine resulted in the first locomotives being shipped with 4,300  hp (3,210 kW) 16-cylinder 710G engines, making them similar to

11448-576: Was re-routed to this new southerly line, which connected numerous emergent small cities across the region. Independent railways and subsidiaries that were eventually merged into the CPR in connection with this route were the Shuswap and Okanagan Railway , the Kaslo and Slocan Railway , the Columbia and Kootenay Railway , the Columbia and Western Railway and various others. Under the initial contract with

11556-475: Was sometimes applied in British colonies as well, such as Kenya (British East Africa) . where Since taxable horsepower was computed based on bore and number of cylinders, not based on actual displacement, it gave rise to engines with "undersquare" dimensions (bore smaller than stroke), which tended to impose an artificially low limit on rotational speed , hampering the potential power output and efficiency of

11664-565: Was unsuccessful. In 2015–16 Canadian Pacific sought to merge with American railway Norfolk Southern . and wanted to have a shareholder vote on it. CP ultimately terminated its efforts to merge on April 11, 2016. On February 4, 2019, a loaded grain train ran away from the siding at Partridge just above the Upper Spiral Tunnel in Kicking Horse Pass . The 112-car grain train with three locomotives derailed into
