Grand Trunk Pacific / Canadian Northern / Chicago & Grand Trunk / Grand Trunk / Intercolonial / Canadian National 4-4-0 "American" Type Locomotives

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

Class 1 / A-15a (Locobase 6773)

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

A lesser-known US builder supplied these locomotives to the Grand Trunk as a single batch; they were Hinkley works #1622-1646. Given their numbers, they may have been the very first on the line.

By the time the CN prepared the diagram from which the data come, 5 had dropped by the wayside. The rest were "retired from records Dec. 1926", according to a hand-written notation on the diagram.

Class A-12 (CNR) (Locobase 6771)

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

A broken set of Eight-wheelers that, by the time CN had drafted a diagram, was down to three locomotives.

Class A-14 (CNR) (Locobase 6772)

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

A set of relatively old Eight-Wheelers 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. The very similar B-10-a had taller drivers; see Locobase 7964.

Class A-15-c (CNR) (Locobase 6774)

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

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 -- Locobase believes that more than 13 engines made up the class..

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.

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

Class A-16-a (CNR) (Locobase 7959)

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

Locobase doesn't know how big the class was originally, but by the time the CN diagrammed the class, only the one remained and it had been scrapped in November 1923.

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

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

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 collection.

Class A-3 (CNR) (Locobase 6769)

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

The original owner of these Eight-wheelers is lost to Locobase. The CN diagram shows earlier numbers assigned by the Canadian Government Railways (CGR) as 1034, 1036, 4040, and 1038, suggesting a larger class of diverse origins.

Locobase 883 shows another Grant-built class from the same year. Although destined for the Washington & Columbia (later part of the Northern Pacific), that class has very similar dimensions to the Canadian engines.

Class A-4 (CNR) (Locobase 7958)

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

This small CGR Eight-wheeler probably 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. A slightly different design can be found on Locobase 7961.

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 collection.

These small CGR Eight-wheelers probably 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. 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 collection.

Built for the GTR in 1883 by the railroad, the 4-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-10-a (CNR) (Locobase 7964)

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

Like the 63" drivered A14-a, these Rhodies came on to the GTR quite early in its existence. 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 B-11-a (CNR) (Locobase 7965)

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

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.

Class B-12-a (CNR) (Locobase 7966)

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

Class B-26-a (CNR) (Locobase 7967)

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

Locobase supposes that 240 sq ft would be a likely superheater area, but he cannot be sure. Unfortunately, the diagram doesn't provide a separate value for the superheater.

Class B-5-a, -b (CNR) (Locobase 7962)

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

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"-diameter cylinders and the boiler was set to 170 psi for a tractive effort of 14,620 lb. The B-5-b operated as shown.

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

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

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 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 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.
