Class Details by Steve Llanso of Sweat House Media

Class H-9 / A-12 (CNR) (Locobase 6771)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also "Northern Rlwy of Canada Group," Charles Cooper's Railway Pages at [], last accessed 25 November 2013. Works numbers were 311-317 in 1886 and

Kingston, Ontario builder CLC delivered seven Eight-wheelers to the N&NW only a year or so before that railway group was taken over by the Grand Trunk in early 1887. A year after that, two more were produced for the N&NW (73-74), but assigned GT numbers very shortly thereafter. By the time CN took over the GT, the number of locomotives in the class had been reduced to three.

(CN's diagram compiler apparently misread the Grand Trunk's specs because he credited these engines with 1,693 sq ft of heating surface. A look at the 1913 GT book shows that the earlier railroad gave that number as the locomotive's slow-speed, level-track haulage capacity.)


Class 1 / A-25a (Locobase 15635)

Data from CN Steam Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange. See also "Bay of Quinte Railway" on the CanadaRail site at [], last accessed 25 November 2013.

Chartered as the Napanee, Tamworth and Quebec Railway Company (NT&QR) in 1879, the BofQ finally emerged from extensions and renamings and combinations in 1897. At its greatest extent, the BofQ extended 83 miles (143 km) from Harrowsmith to Bannockburn


Class 1 / H-2 / A-15a (Locobase 6773)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 1622-1646

A lesser-known US builder supplied these locomotives to the Grand Trunk as a single batch; they were Hinkley . As suggested by their numbers, these were the very first on the line.

By the time the CN prepared the diagram from which the data comes, five had dropped by the wayside. The rest were "retired from records Dec. 1926", according to a hand-written notation on the diagram. The diagram's heating surface area does not match up with the given tube count of 190 2" tubes. When Locobase calculates the tube area needed to result in 954 sq ft, he comes up with 156 2" tubes. (1 5/8" diameter tubes--rare but not unheard of--would geneerate a similar area using 190 tubes.)


Class 1 / X-4 (Locobase 10462)

Data from "Locomotives from the St Louis Exhibition," Engineering, Vol 77 (8 July 1904), p. 44 and "Locomotive Exhibits at St Louis", The Locomotive Magazine, Vol X (15 August 1904), p. 144. See also Canadian National Steam Locomotive Assorted locomotive diagrams supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 616-619, 625.

As the author of the LM's report on the 1904 Louisiana Purchase Exposition lamented the absence of British locomotives in the displays of technology, he took some solace in the CLC's offering of this little Eight-wheeler before conceding "[B]ut [it] is typically American in design," he observed, adding with some grace,"and is indeed an excellent example of the adaptability of the 'American' pattern to all gauges."

Like all of the PEIR's engines, this was a small example that reflected in all likelihood the light rail of the 211-mile system.


Class 136 / A-8 (Locobase 15634)

Data from CN Steam Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange.

The diagram referenced above does not give the heating surface area of this small Eight-wheeler. It was Fleming Locomotive Works 27th locomotive when it arrived on the ICR in 1883 as part of a three-engine order. Each was rebuilt in the late 1890s with the 118 finishing last in1901. All were later given CGR numbers 1072-1074, but 1072 and 1074 were was scrapped in 1917.

Only 1073 survived to gain a CNR number of 118 before being scrapped in May 1925.


Class A-20-c (CNR) (Locobase 6775)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers 615, 628 in 1904 and 746 in 1906.

The COR merged 5 April 1909 with the Canadian Northern.

Locobase notes that the diagram had only the tube heating surface. 120 & 122 were "removed from records" in December 1924. The 121 was described as "scrapped July 1925."


Class A-24-a (CNR) (Locobase 7960)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 29907 in June 1904 and 40667 in June 1906.

The BW&NW arose in October 1903 out of the bankruptcy of the Brockville, Westport & Sault Ste Marie Railway (probably because the railway never actually reached Sault Ste Marie). It in turn saw its shares bought up by the two principals of the Canadian Northern (William Mackenzie and Donald Mann) in April 1910.

The CNor was in turn amalgamated with the Canadian National on 20 December 1918 and these two locomotives were placed in their own class. The 123 went to the scrapyard soon afterward in 1922, but the 124 held on until 1931.


Class A-4 (Locobase 7958)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

This small CGR Eight-wheeler operated on the Intercolonial at first, but that railroad was absorbed in 1919 by the Canadian Government Railway, which later formed part of the CN. Delivered in 1880 by Danforth, Cooke (works numbers 1182-1183) with 16 1/2" (419 mm) cylinders, the class was rebuilt by the ICR in 1896.

The CGR took over all three in 1913, but only the latter two survived to be absorbed by the CNR as 110-111. 110 was scrapped in 1923 and 111 in 1928.


Class A-5/ B-7-a (CNR) (Locobase 7961)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

These small CGR Eight-wheelers were delivered to the Intercolonial by Hinkley in 1880. The specifications reflect the rebuild by the ICR in 1896. 114 (renumbered 1045) was sold in 1914 to the Moncton & Buctouche as their 3. The other three were taken into the Canadian National in 1919 and given Canadian Government Railways numbers 1043-1044, 1046. 1044 was sold to the Kent Northern Railway in 1922 as their #6, 1046 was scrapped in the same year, so only the 1043 was renumbered 112 by the CNR in 1923.

The A-5s had smaller drivers (64" and 62", respectively), but were otherwise identical to the B-7-a shown in the specifications. Naturally the shorter drivers made for higher tractive effort.


Class A-9 (CNR) (Locobase 6770)

Data from CN to 1953 Locomotive Diagrams and GT 6 - 1913 Description of Locomotives Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

Built for the GTR in 1883 by the railroad, the four-engine class had been reduced by one by 1913. Of the three remaining, 1994 was scrapped in August 1918 and 1997 was sold in December 1919. For reasons probably related to its light axle loading, the Canadian National retained 1996 for several years.


Class B-16-a (Locobase 5589)

Data from [] (19 June 2003), Rene Gourley's website describing this Eastern Canadian railway. See also Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 18, p. 259. Works numbers were 13699-13700 in August 1893, 13991-13992 in April 1894, and 14296 in October 1895.

The specifications featured on the proto87 website indicated that the 20's design had arch tubes. (The fire bricks are to rest on water tubes "as on Canada Atl 12", but the specs caution, the tubes "not to enter the crown sheet". ) The last of the five was originally delivered to the Central Vermont as #30, reassigned to Vermont & Provincial Line, and absorbed by the CAR in 1899.

When the O A & PS was absorbed by the Canada Atlantic, these engines were renumbered. The Grand Trunk fully amalgamated the CA in 1914, renumbered these locomotives twice more, then yielded to the Canadian National in 1920 as their 304-308.

All were scrapped in 1925.

According to a Locomotive and Railroad History Bulletin (147) cited in proto87, the two engines then had dimensions of 18" x 26", but the calculation suggests that the LRHS was not correct.

NB:The heating surface areas are good estimates derived from a comparison with the #21 of the Matanzas Railroad of Cuba delivered in 1903 and described in Locobase 11540. Not only did both have the same number of identical-diameter boiler tubes running the same length (less 1/2 inch), they also had grates and fireboxes that measured identically to the quarter-inch.


Class B-5-c (CNR) (Locobase 7963)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

As noted in Locobase 7962, the CNR's B-5 class was made up of several subtypes, but this one seems to have had most members. B-5-c were virtually identical to the B-5-a, except for having a longer set of boiler tubes.


Class D-3/D-4/D-21//B-5-a, -b (CNR) (Locobase 7962)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works number were 273-277 in 1883, 278-291 in 1884.

When the CNR designated all of the B-5s, they seem to have been grouping according to the boiler dimensions and tube count. These two passenger engines (and likely others - the diagram only showed the survivors as of the early 1920s) shared a common boiler and grate. The B-5a had 17" (645 mm) diameter cylinders and the boiler was set to 170 psi for a tractive effort of 14,620 lb (6,632 kg). The B-5-b operated as shown.


Class D-4 / A-3 (Locobase 6769)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 340-345 in July 1888, 346-351 in August, 352-353 in September.

It's unlikely that the data presented in this entry exactly match the specifications of the Intercolonial's original class of Eight-wheelers. Yet the differences couldn't have been very great, given that the basic size, grate, and cylinder volume remained essentially unchanged. Their unusual numbering sequence reflects the use of some of the engines as gap fillers.

As the Canadian Government worked on a way to save the "other" transcontinental railway, these engines all migrated to the nationalized Canadian Government Railway in 1913, At this point the class was numbered serially from 1032 to 1043. The last two received 1097-1098.

Most were sold for scrap in 1917. When the Canadian National took over the CGR, it took four of the locomotives--1034, 1036, 1038, 1040--and renumbered them 105-106, 108, 107, respectively.


Class H (Locobase 9063)

Data from Transactions of the Canadian Society of Civil Engineers By Canadian Society of Civil Engineers, v.3-4 (1889-90), the January 3, 1889 session.

As part of the President Samuel Keefer's address, he repeated some information supplied to him by Herbert Wallis, Mechanical Superintendent of the GTR. Wallis's summary included the standard passenger and standard freight engines of the road at the time.

This particular class does not appear in the Locomotive Diagram books supplied to Locobase by Allen Stanley. However, Stanley also supplied the Grand Trunk's Description of Locomotives, which shows 2 engines from 1881 with the same boiler and grate aras. Their cylinders are credited with a 26"stroke, 2" longer than those referenced by Keefer, but Locobase believes they are the same engines.


Class H-1 / B-26-a (CNR) (Locobase 7967)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Montreal Locomotive Works numbers were 44822-44851 in 1908, followed by Canadian Foundry works numbers 909-928, and ending with MLW works numbers 46078-46102 in 1909.

These locomotives were sent west to the Canadian prairie provinces.

NB: Unfortunately, the diagram doesn't provide a separate value for the superheater. But Locobase estimates the superheater area based on similar flue counts and lengths for other locomotives.


Class H-2 / A-15-c (CNR) (Locobase 6774)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

This seems to have been a relatively large class. The lower number was built by the Grand Trunk in 1889, the higher by Brooks in 1890 (works numbers were 1619-1628.

The design was similar to that of the Hinkleys that went into service several years earlier (Locobase 6773). But the firebox layout had changed, for while the grate was substantially bigger the overall direct heating surface area changed very little.The Grand Trunk later renumbered the class2287-2289, 2297-2306.

By the time the CN diagrammed the class, only two remained. These were "retired from records Dec. 1926", according to the handwritten annotation.

As with the A-15a diagram, the diagram's heating surface area does not match up with the given tube count of 190 2" tubes. When Locobase calculates the tube area needed to result in 954 sq ft, he comes up with 162 2" tubes. (1 3/4" diameter tubes--rare but not unheard of--would geneerate a similar area using 185 tubes.)


Class H-2 / B-11-a (CNR) (Locobase 7965)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 1209-1217 in September 1882.

In the early 80s, the GTR bought some of its first express passenger engines. Even though they had a relatively large firebox heating surface and 73" drivers, their boilers were still a bit small to sustain high-speed operation for long runs.

They were renumbered twice by the Grand Trunk. The first series took new numbers in this order in 1905: 1071, 1069, 1072-1077, 1070, 1078. In 1910, the nonet received the new set as follows: 2242, 2179, 2243-2248, 2241, 2249. (One would expect 2179 to be 2140, but Locobase isn't sure.) Canadian National took them in the early 1920s and numbered in 1923 in this squence: 255, 253, 256-261, 254, 262.

Seven were scrapped in 1927, two in April 1928, and the last--258-- in December 1930.


Class H-2 / B-12-a (CNR) (Locobase 7966)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

Eight of the 4-4-0s on the NWGT and the C> were rebuilt by the latter to the configuration shown in this entry. They were numbered and renumbered several times, the final set of numbers being 2283-2286, 2290, 2294-2296.


Class H-3/A-16-a (CNR) (Locobase 7959)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 2281-2292 in 1893.

By the time the CN diagrammed the class, only the one remained and it had been scrapped in November 1923.


Class H-5/H-8 // B-15 (CNR) (Locobase 15637)

Data from CN Steam Locomotive Diagrams Asstd supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 2281-2292 in 1893.

Locobase isn't sure but it appears that all of these locomotives were delivered with straight boilers. The H-5s--works numbers 1274-1278 in 1893--were the ones who retained those boilers while the H-8s received Belpaire fireboxes in 1904.


Class H-7 / B-16b (Locobase 15641)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 20, p. 219. Works numbers were 15067-15068 in 1896.

Locobase wonders if this pair was built to compare the efficiency of a smaller boiler with fewer tubes of smaller diameter with the H-2s supplied by Baldwin over the previous couple of years (Locobase 5589). If so, later Grand Trunk descriptions suggest that the small-tube argument lost as these two would credited in 1913 with exactly the same 1,521 sq ft heating surface area as were the earlier engines.

When the Canadian National took over the Grand Trunk in 1920, it placed the two in their own subclass (B-16b) and renumbered them

NB:The heating surface areas are good estimates derived from a comparison with the #21 of the Matanzas Railroad of Cuba delivered in 1903 and described in Locobase 11540. Not only did both have the same number of identical-diameter boiler tubes running the same length (less 1/2 inch), they also had grates and fireboxes that measured identically to the quarter-inch.


Class H-8 / B-18 (CNR) (Locobase 15642)

Data from CN Steam Locomotive Diagrams Asstd supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange.

At least when they arrived on the Canadian National, this pair of H-2s were fitted with Belpaire boilers in the mid-to-late 1890s. But there were more tubes in the boiler, probably because the cylinder volume was larger by the adoption of a 2" (50.8 mm) longer stroke.


Class H1 / B-26a (Locobase 11366)

Data from "Equipment and Supplies: Locomotive Building, Railway Age Gazette, Vol 44 (6 December 1907), p. 819-820. Canadian Foundry Company works numbers were 909-928. Monteral Locomotive Works contributed 30.

Relatively small, but equipped with a 200-psi boiler that conferred a decent level of power for these road engines-of-all-work. Most went directly to the Canadian National when that system began operation in 1920. Two went to the Canadian Northern in 1918 as 75-76 and thence to the CNR.

All were scrapped in the mid-to-late-1920s.


Class J-3 / A-14 (CNR) (Locobase 6772)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

This design and the very similar CNR B-10-a (which had taller drivers; see Locobase 7964) was built in great numbers (over 150 all told) for the Great Western of Canada over a four-year span. At the time, the design had 16" x 24" cylinders and two sizes of drivers--54" and 66".

They were all rebuilt at some point to the specifications shown above. A-14 represents the set of 63" ex-GTR that were brought into the CNR as one class. 140 was significantly lighter than the others, putting just 38,000 lb on the drivers and 64,000 lb on all four axles.


Class J-3 / B-10-a (CNR) (Locobase 7964)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 207-210, 236-240, 244, 258-259, 279, 289.

Like the 63" drivered A14-a (Locobase 6772), these Rhodies came onto the GWR in 1870-1873 in quite large quantities (over 150 locomotives in all). At the time, the design had 16" x 24" cylinders and two sizes of drivers--54" and 66". Locobase has grouped all the 66" driver locomotives in this entry.

Their GW numbers were 855-858, 861-865, 911, 866-867, 869, 872.

They were all rebuilt at some point to the specifications shown above. Several renumberings by both the GW and the Grand Trunk resulted in the 1910 set (which didn't include two that had already been scrapped) of 2131-2132, 2130, 2129, 2124, 2127, 2125, 2133, 2128, 2136, 2134, and 2137. When the CNR took over the Grand Trunk, 2129, 2125, 2143, 2139, and 2166 (the latter two had been delivered as 16" x 22" locomotives) were renumbered 249, 248, 251, 250, and 252.

From the CNR's point of view, the B-10-a differed in being intended for more purely passenger work Of the group, some had 69" drivers, others 70" (by 1924, 248 (1870) and 251 (1872) had the 69" wheels, the 249 and 252 had 70"). They were otherwise identical to each other and to the A-14s.


Class R/B-26a (Locobase 9067)

Data from CN to 1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 1301-1310 in 1899.

Renumbered several times by three different railroads, this class was scrapped in 1925 (317) and 1927 (the remainder of the class).
