72-527: The tunnel was originally proposed by the Canadian Northern Railway (CNoR) to provide access to Downtown Montreal without having to cross the already-congested area south of Mount Royal or the route around it to the east. The cost of the tunnel, along with an expansion to the west coast of Canada, caused CNoR to struggle financially before it was nationalized in 1918. Canadian National Railways (CNR), formed from CNoR and several other lines, took over

144-580: A $ 289 million modernization of the Mount Royal Tunnel line, including $ 130 million awarded to Bombardier for 58 new commuter rail cars. Stations, track, electrification and signalling systems were all upgraded, in addition to the tunnel structure itself. On June 2, 1995, the last of the GE boxcab electric-powered locomotives delivered to CNoR in 1916–1917 for use in the tunnel were retired by CN after nearly 77 years of service. Locomotive 601, which in 1918 pulled

216-736: A charter to build westward to the mouth of the Skeena River was alarmed, but in no hurry, because it believed the GTPR would choose one of the more northerly passes to cross the Canadian Rockies , leaving the Yellowhead Pass for the CNoR. Despite promptings, the GTP was unwilling to collaborate with the CNoR in any joint construction. In 1905, CNoR reached Edmonton , just as part of the old NWT had changed into

288-441: A condition for further funding, the government became the majority shareholder. On September 6, 1918, the directors, Mackenzie and Mann, resigned, replaced by a government-appointed board. Subsequently, CNoR executive David Blyth Hanna and his team managed not only CNoR operations but also the federally owned Canadian Government Railways (CGR). On December 20, 1918, a Privy Council order directed CNoR and CGR to be managed under

At its 1923 merger into the Canadian National Railway ( reporting mark CN ), the CNoR owned a main line between Quebec City and Vancouver via Ottawa , Winnipeg , and Edmonton . The network had its start in

504-619: A part of the Mascouche line . In addition, two new stations are being constructed mid-tunnel directly below existing stations of the Montreal Metro , specifically Édouard-Montpetit and McGill stations. The new platforms will allow direct connection to the Metro from the REM, though in the case of Édouard-Montpetit this will involve a long trip by elevator ; it will become Canada's deepest transit station at

576-505: A standard gauge of 4 ft  8 + 1 ⁄ 2  in ( 1,435 mm ), and those in Ireland to a new standard gauge of 5 ft 3 in ( 1,600 mm ). In Great Britain, Stephenson's gauge was chosen on the grounds that existing lines of this gauge were eight times longer than those of the rival 7 ft or 2,134 mm (later 7 ft  1 ⁄ 4  in or 2,140 mm ) gauge adopted principally by

648-423: A time-consuming and expensive process. The result was the adoption throughout a large part of the world of a "standard gauge" of 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ), allowing interconnectivity and interoperability. A popular legend that has circulated since at least 1937 traces the origin of the 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) gauge even further back than

720-453: A trans-Pacific service were mothballed. In 1914, to develop a resort on Grand Beach , CNoR bought a 150-acre (0.61 km ) homestead north of Winnipeg on the shores of Lake Winnipeg, By 1914, with the company's financial predicament threatening the solvency of its major financier, the Bank of Commerce , the CNoR appealed for government help.

864-480: Is defined in U.S. customary / Imperial units as exactly "four feet eight and one half inches", which is equivalent to 1,435.1   mm. As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – a " gauge break " – loads had to be unloaded from one set of rail cars and reloaded onto another,

936-560: Is now expected to reopen fall 2025, more than five years later. The reopening has been delayed due to the discovery of leftover explosives used during the original excavation of the tunnel, greater than expected deterioration at the south end of the tunnel, and various issues caused by the COVID-19 pandemic . As part of the refurbishment providing exclusive use for the Réseau express métropolitain , two new stations will be added mid-tunnel. The tunnel

1008-556: Is the most widely used track gauge around the world, with about 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia , Finland , Uzbekistan , and some line sections in Spain . The distance between the inside edges of the rails is defined to be 1,435 mm except in the United States, Canada, and on some heritage British lines, where it

1080-725: The Department of Railways and Canals . At the same time, the newly appointed board at CNoR was directed to take over the operation of the government-owned Canadian Government Railways (CGR). On December 20, 1918, the Privy Council issued an order creating the Canadian National Railways (CNR) to operate CNoR, CGR and eventually other bankrupt private-sector railways. Ironically, the Grand Trunk became part of CNR in 1923, giving CNR better routes to Ottawa and Toronto and relegating

1152-618: The Duluth, Winnipeg and Pacific Railway , forms part of a key CN connection between Chicago and Winnipeg . Standard gauge A standard-gauge railway is a railway with a track gauge of 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ). The standard gauge is also called Stephenson gauge (after George Stephenson ), international gauge , UIC gauge , uniform gauge , normal gauge in Europe, and SGR in East Africa. It

1224-598: The Liverpool and Manchester Railway , authorised in 1826 and opened 30 September 1830. The extra half inch was not regarded at first as very significant, and some early trains ran on both gauges daily without compromising safety. The success of this project led to Stephenson and his son Robert being employed to engineer several other larger railway projects. Thus the 4 ft  8 + 1 ⁄ 2  in ( 1,435 mm ) gauge became widespread and dominant in Britain. Robert

1296-506: The Montreal melon were bought by the builders to make way for the tracks: "There were two years of preliminary bargaining, after which currency by the satchel full was paid over to the owners of the farms which made the Montreal melons famous, in the purchase of their land. More than $ 1,500,000 was paid out in that way, with currency, in the rush of land speculation that followed the announcement of

1368-471: The Mount Royal Tunnel project. CNoR was heavily indebted to banks and governments, and its profitable branchlines in the prairie provinces — "Canada's breadbasket" — would not generate enough revenue to cover construction costs in other areas. Unable to meet its debts, the company became desperate for financial aid. In 1917, the federal government effectively took control of the company. As

1440-476: The 1890s and 1900s had been relatively frugal, largely by acquiring bankrupt companies or finishing failed construction projects. By the 1910s, significant expenses were accumulating. The CNoR started construction west of Edmonton in 1910, fully two years later than GTPR. The construction through the Rockies, which was expensive, largely paralleled the GTPR line of 1911, creating about 100 miles of duplication. However,

1512-558: The 1890s, they reached Swan River , and continued building north between the Porcupine Hills to the west and Lake Winnipegosis to the east. In 1900, Mackenzie and Mann directed this northern line west into the Northwest Territories (later Saskatchewan ), where it eventually terminated at E.R. Wood (later Erwood ). This northwestern line mainly carried lumber and was extended to Melfort between 1903 and 1905. In 1907,

1584-522: The 1930s to the 1960s, interrupted by the Great Depression and the Second World War . A new terminal, begun in 1931, opened as Central Station on July 14, 1943, resulting in the closure of the "temporary" CNoR-era Tunnel Terminal near the same location. Central Station consolidated CNR's passenger terminals in the city and also replaced Bonaventure Station which CNR had inherited from GTR. In

1656-559: The CNoR, the line extended south of Lake of the Woods into northern Minnesota before heading northeast through Rainy River District to the head of navigation on the Great Lakes . The Winnipeg-Port Arthur line was completed on December 30, 1901, with the last spike being driven just east of Atikokan station by Ontario's Commissioner of Crown Lands , Elihu Davis . Meanwhile, Mackenzie and Mann expanded their prairie branch line operations to feed

1728-563: The Canadian Parliament pressured Mackenzie and Mann to continue building more rail towards Hudson Bay. In that year, they created a junction on the Erwood to Melfort line near the mouth of the Etoimami river, where Fort Red Deer River existed, and a line was extended north to The Pas . By 1910, the settlement at this junction was renamed Hudson Bay Junction , and the line was completed between

1800-889: The Great Western Railway. It allowed the broad-gauge companies in Great Britain to continue with their tracks and expand their networks within the "Limits of Deviation" and the exceptions defined in the Act. After an intervening period of mixed-gauge operation (tracks were laid with three rails), the Great Western Railway finally completed the conversion of its network to standard gauge in 1892. In North East England, some early lines in colliery ( coal mining ) areas were 4 ft 8 in ( 1,422 mm ), while in Scotland some early lines were 4 ft 6 in ( 1,372 mm ). The British gauges converged starting from 1846 as

1872-467: The Mount-Royal Tunnel. Before 1995, Via Rail trains to/from Northern Quebec and the northern route to Quebec City (cancelled in 1990) also used the tunnel, being hauled up by boxcabs pre-1990, and coasting downhill. This practice was eliminated when the catenary and signalling were replaced in 1995. The old catenary was 3000 V DC (upgraded from the original 2400 V DC in the early 1980s) and

1944-631: The Netherlands for the Hollandsche IJzeren Spoorweg-Maatschappij ), but for interoperability reasons (the first rail service between Paris and Berlin began in 1849, first Chaix timetable) Germany adopted standard gauges, as did most other European countries. The modern method of measuring rail gauge was agreed in the first Berne rail convention of 1886. Several lines were initially built as standard gauge but were later converted to another gauge for cost or for compatibility reasons. 2,295 km (1,426 mi) Victoria built

2016-656: The Skeena, the CNoR accepted BC government subsidies to switch to the Vancouver area. When the GTPR selected the Yellowhead route, CNoR protests created some delay but could not overturn he decision. In 1911, CNoR workers started on a townsite named Port Mann on the Fraser River. This townsite would accommodate new car shops, and from there, rail-lines would extend to Vancouver and the Fraser River delta. CNoR's initial expansion in

2088-582: The St-Laurent subdivision on the way to Mascouche. Trains were operated with dual-powered ALP-45DP locomotives, and initially ran under electric power to the Ahuntsic station, where they changed over to diesel. Service through the Mount Royal Tunnel ended in May 2020. The Réseau express métropolitain is replacing this part of the Réseau de transport métropolitain along with the entire Deux-Montagnes line as well as

2160-563: The Stony Plain line meant frequent crossings over the Grand Trunk Pacific line which had been laid in the meantime. Instead CNoR decided to leave Edmonton through St. Albert. (A bump on 124th Street near Stony Plain Road is remnant of the constructed but abandoned road-bed.) CNoR's terminus on the coast changed over time. Rather than competing with the GTPR in having a terminal at the mouth of

2232-472: The Toronto – Parry Sound line to Ottawa and on to Montreal . In 1910 a direct Toronto–Montreal line was built. In 1911, federal funding enabled construction of the line Montreal – Ottawa – Capreol – Port Arthur. In 1912, with GTR and CPR holding the ideal southern routes around Mount Royal to downtown Montreal, CNoR started building a double-tracked mainline north by excavating the Mount Royal Tunnel . In 1910

2304-599: The acquisition of branchlines in southwestern Nova Scotia (the Halifax and Southwestern Railway ) and western Cape Breton Island (the Inverness and Richmond Railway ). Other acquisitions were in southern Ontario and a connecting line was built from Toronto to Parry Sound . In 1908, a line, which under later CN ownership was known as the Alderdale Subdivision , was built east from a connection at Capreol, Ontario , on

2376-629: The advantages of equipment interchange became increasingly apparent. By the 1890s, the entire network was converted to standard gauge. The Royal Commission made no comment about small lines narrower than standard gauge (to be called "narrow gauge"), such as the Ffestiniog Railway . Thus it permitted a future multiplicity of narrow gauges in the UK. It also made no comments about future gauges in British colonies, which allowed various gauges to be adopted across

2448-476: The coal mines of County Durham . He favoured 4 ft 8 in ( 1,422 mm ) for wagonways in Northumberland and Durham , and used it on his Killingworth line. The Hetton and Springwell wagonways also used this gauge. Stephenson's Stockton and Darlington railway (S&DR) was built primarily to transport coal from mines near Shildon to the port at Stockton-on-Tees . Opening in 1825,

Snopes categorised this legend as "false", but commented that it "is perhaps more fairly labeled as 'Partly true, but for trivial and unremarkable reasons. ' " The historical tendency to place the wheels of horse-drawn vehicles around 5 ft ( 1,524 mm ) apart probably derives from

2592-525: The colonies. Parts of the United States, mainly in the Northeast, adopted the same gauge, because some early trains were purchased from Britain. The American gauges converged, as the advantages of equipment interchange became increasingly apparent. Notably, all the 5 ft ( 1,524 mm ) broad gauge track in the South was converted to "almost standard" gauge 4 ft 9 in ( 1,448 mm ) over

2664-689: The company entered the trans-Atlantic liner business with the founding of the Canadian Northern Steamship Company. The subsidiary acquired two liners from the Egyptian Mail Steamship Company and operated them under its Royal Line brand. The pair of ships were renamed upon purchase— Cairo became Royal Edward and Heliopolis became Royal George —and refitted for travel on the North Atlantic. In Royal Line service, Royal Edward sailed from Avonmouth to Montreal in

2736-576: The connection to Port Arthur. From a series of disconnected railways and charters, the network became 1,200 miles of profitable and continuous track that covered most of the prairies by 1902. After receiving grants from the Province of Manitoba and the Dominion of Canada in the 1890s, Mackenzie and Mann began building lines further north in Manitoba, with the intention of eventually reaching Hudson Bay . Throughout

In continental Europe, France and Belgium adopted a 1,500 mm ( 4 ft  11 + 1 ⁄ 16  in ) gauge (measured between the midpoints of each rail's profile ) for their early railways. The gauge between the interior edges of the rails (the measurement adopted from 1844) differed slightly between countries, and even between networks within

2880-735: The first railways to the 5 ft 3 in ( 1,600 mm ) Irish broad gauge. New South Wales then built to the standard gauge, so trains had to stop on the border and passengers transferred, which was only rectified in the 1960s.

On February 28, 2014, the Agence metropolitaine de transport (AMT) purchased the Deux-Montagnes line from CN for $ 97 million. The agreement gave CN trackage rights for freight trains outside two rush-hour exclusive time windows (08:30–15:30 and 20:30–05:30). Until May 2020, commuter trains from Exo's Deux-Montagnes and Mascouche lines used

3024-486: The independent branchlines that were being constructed in Manitoba in the 1880s and 1890s as a response to the monopoly exercised by Canadian Pacific Railway (CPR). Many such lines were built with the sponsorship of the provincial government, which sought to subsidize local competition to the federally subsidized CPR; however, significant competition was also provided by the encroaching Northern Pacific Railway (NPR) from

3096-429: The initial gauge of 4 ft 8 in ( 1,422 mm ) was set to accommodate the existing gauge of hundreds of horse-drawn chaldron wagons that were already in use on the wagonways in the mines. The railway used this gauge for 15 years before a change was made, debuting around 1850, to the 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) gauge. The historic Mount Washington Cog Railway ,

3168-425: The junction and The Pas. The long section of rail between The Pas and Churchill was never completed by CNoR. However, after CNoR was acquired by CN , the line was completed in 1929. (see Hudson Bay Railway ) Once elected in 1896, Prime Minister Wilfrid Laurier was eager for a second transcontinental. However, an expansion of the non- CPR railways west of Alberta would be a mammoth questionable gamble for

3240-598: The just-completed tunnel. When CNR also took over the Grand Trunk Railway (GTR) in 1923, access to Ottawa and Toronto along the GTR lines made the tunnel largely redundant, and it was limited mostly to branch lines. The structure gauge of the Mount Royal Tunnel limits the height of bilevel cars to 14 feet 6 inches (4.42 m). Until 2014, the only trains using the tunnel were commuter trains from Exo 's Deux-Montagnes service. From December 2014 to May 2020, it

3312-629: The largest costs were from building on "the wrong side" of the Thompson and Fraser rivers in the Coast Mountains of British Columbia. CPR already had trackage on the desirable banks, forcing the CNoR to blast tunnels and ledges out of these canyons. The most infamous construction folly on the CNoR in British Columbia happened in 1913, when blasting for a passage for the railway at Hells Gate triggered an enormous landslide which partially blocked

3384-552: The late 1950s, the remainder of the CNoR lands acquired in downtown Montreal during the Mount Royal Tunnel project were developed by CNR. The signature Queen Elizabeth Hotel opened in 1958, followed by the CN (name/acronym change in 1960) headquarters building in 1961 and Place Ville-Marie in 1962. On July 1, 1982, CN signed a 10-year agreement with STCUM whereby CN operated the line under contract to STCUM's commuter rail service. On February 12, 1992, Quebec's provincial government announced

3456-471: The mid-1910s. The first train, with locomotive 601 leading, ran through the tunnel October 21, 1918. The event was little-noticed due to the still-ongoing war and a ban on large public gatherings due to the Spanish flu epidemic . On September 6, 1918, the insolvent CNoR was nationalized by the federal government when its board of directors was replaced by a government appointed board of management, implemented by

3528-577: The name Canadian National Railway (CNR) as a means to simplify funding and operations, but CNoR and CGR would not formally merge and cease corporate existence until January 20, 1923, the date Parliament passed the final act to incorporate CNR. Significant portions of the old CNoR system survive under CN (as the CNR has been known since 1960); for example: The majority of CN's former CNoR branchline network across Canada has either been abandoned or sold to shortline operators. An important U.S. subsidiary of CNoR,

Mackenzie and Mann began their first significant expansion outside of the prairies with the purchase of Great Lakes steamships, the Quebec and Lake St-John Railway  [ fr ] (1906) into northern Quebec 's Saguenay region and

3672-400: The new catenary is 25 kV AC . The new signalling is CTC . The ventilation shaft is too small to allow the use of diesel electric locomotives in the tunnel. As part of the change to light-rail standards of the REM, the double-tracking of the line from Bois-Franc to Roxboro-Pierrefonds is taking place, which will enable the REM to significantly increase the number of trains on the line. There

3744-445: The north and east sides of Mount Royal. To finance the costly tunnel option, CNoR planned to develop the low-valued farmland north of Mount Royal into a model community which was named the Town of Mount Royal . CNoR also planned a downtown terminal and associated office and retail developments for low-priced lands at de la Gauchetière Street and McGill College Avenue. Several farms which grew

3816-591: The old 4 ft ( 1,219 mm ) plateway was relaid to 5 ft ( 1,524 mm ) so that Blenkinsop's engine could be used. Others were 4 ft 4 in ( 1,321 mm ) (in Beamish ) or 4 ft  7 + 1 ⁄ 2  in ( 1,410 mm ) (in Bigges Main (in Wallsend ), Kenton , and Coxlodge ). English railway pioneer George Stephenson spent much of his early engineering career working for

3888-522: The operators. Adding an equally costly route to supplement the existing uneconomical CP track through Ontario seemed more ludicrous. At the time, the CNoR planned to advance no further west than Edmonton. In 1902, the GTR held talks with Laurier and agreed to build a transcontinental under the auspices of the GTPR for the western portion, with the eastern portion built by the government-owned NTR . The CNoR, which had

3960-708: The plan. One farmer was paid $ 117,000 and another farm brought $ 781,783." In 1911, the Canadian Northern Montreal Tunnel and Terminal Company was incorporated to build the tunnel and terminal. It was renamed Mount Royal Tunnel and Terminal Company in 1914, and was a wholly owned subsidiary of CNoR. Construction started at the west portal on July 8, 1912. On December 10, 1913, crews from the east and west portals met beneath Mount Royal; they were out of alignment by 1 inch (2.5 cm). The bore measures approximately 5 kilometres (3.1 mi) and has an ascending grade of 0.6% westbound. CNoR placed an order with General Electric in 1914 for 6 boxcab electric-powered locomotives for use in

4032-414: The province of Alberta . The rail-line crossed the North Saskatchewan River at Fort Saskatchewan, coming into Edmonton from the northeast, following the present-day LRT track. After a pause, the CNoR began construction west from Edmonton, and by summer 1907 had gone as far as Stony Plain. A stock market crash that year ceased construction. When construction was resumed in 1910, it was found that extending

4104-436: The rails is better, thus the minimum distance between the wheels (and, by extension, the inside faces of the rail heads ) was the important one. A standard gauge for horse railways never existed, but rough groupings were used; in the north of England none was less than 4 ft ( 1,219 mm ). Wylam colliery's system, built before 1763, was 5 ft ( 1,524 mm ), as was John Blenkinsop 's Middleton Railway ;

4176-411: The rest of the network. All other railways use 1,668 mm ( 5 ft  5 + 21 ⁄ 32  in ) ( broad gauge ) and/or 1,000 mm ( 3 ft  3 + 3 ⁄ 8  in ) metre gauge .

4248-416: The shipping of western grain to European markets as well as the transport of eastern Canadian goods to the West. This line incorporated an existing CNoR line to Lake of the Woods and two local Ontario railways, the Port Arthur, Duluth and Western Railway and the Ontario and Rainy River Railway , whose charters Mackenzie and Mann had acquired in 1897. To reach Port Arthur, which became the lake terminus of

4320-491: The south. Two branchline contractors, Sir William Mackenzie and Sir Donald Mann , took control of the bankrupt Lake Manitoba Railway and Canal Company in January, 1896. The partners expanded their enterprise, in 1897, by building further north into Manitoba's Interlake district as well as east and west of Winnipeg . They also began building and buying lines south to connect with the U.S. border at Pembina, North Dakota , and east to Ontario . The Canadian Northern Railway

4392-456: The summer months and to Halifax in the winter months. At the outbreak of World War I , Royal Edward and Royal George were both requisitioned for use as troopships. On August 13, 1915, the German submarine UB-14 sank Royal Edward , which was transporting troops from Avonmouth to Gallipoli . Royal George was sold to Cunard in 1916, became an emigrant ship in Cherbourg by 1920 and scrapped in 1922 in Wilhelmshaven . Plans for

4464-429: The term "narrow gauge" for gauges less than standard did not arise for many years, until the first such locomotive-hauled passenger railway, the Ffestiniog Railway , was built. In 1845, in the United Kingdom of Great Britain and Ireland , a Royal Commission on Railway Gauges reported in favour of a standard gauge. The subsequent Gauge Act ruled that new passenger-carrying railways in Great Britain should be built to

CNR took over the Mount Royal Tunnel at the time of its completion, along with the virtually empty lands which CNoR's owners, Sir William Mackenzie and Sir Donald Mann , had envisioned would become a signature real estate development. CNR developed this area sporadically from

4608-417: The tunnel; they were delivered in 1916–1917. Both the locomotives and the electrification were very similar to those of the Butte, Anaconda and Pacific Railway . Lining of the tunnel bore with concrete was completed by 1916 and the 2 parallel standard gauge tracks and 2400 V DC catenary were installed by September 1918. Progress was slowed by the First World War and CNoR's ongoing financial difficulties by

4680-479: The width needed to fit a carthorse in between the shafts. Research, however, has been undertaken to support the hypothesis that "the origin of the standard gauge of the railway might result from an interval of wheel ruts of prehistoric ancient carriages".
