Locobase 9069 shows the Grand Trunk's compounds of the same year. The Shore Line's Moguls had a longer stroke and eight fewer tubes. It appears that the entire class remained cross-compounds throughout their careers. 1 and 6 were scrapped in 1929 and 2-5 in 1934."
This engine had the classic form of a boiler tapered just ahead of the firebox, which had the steam dome mounted over the crown sheet, and a long, narrow first course of boiler. It was the first of five built to this design.
The first two were delivered as singles to the Qu'Appelle Long Lake & Saskatchewan and the Quebec & Lake Saint John. The former was later lettered for the Port Arthur Duluth & Western in 1893 and passed into Canadian Northern hands in August 1897 as their 19. The 19 was renumbered 107 in 1912.
When the CNR took over the Canadian Northern's motive power, they gave the 107 number 470. It was scrapped in June 1927."
Baldwin built this Eight-wheeler for part of the network of lines that radiated eastward from Ottawa in the 1870s and 1880s.
The PSC was combined with the Ottawa, Arnprior & Renfrew to become the OA & PS in 1891 and this engine probably helped to open the OA & PS's Ottawa-Amprior segment on 13 September 1893.
The 100 remained on the line as the OA & PS was taken into the Canada Atlantic in 1899, the CAR into the Grand Trunk in 1905, and the GTR into the Canadian National in 1923. Renumbered several times, it bore #501 in class D9-a when it was scrapped in June 1927."
This was the rebuilt pair of Moguls originally supplied by Baldwin in 1902 and described in Locobase 10759. The new boiler had nine fewer tubes that were just a bit shorter.
The 483 was scrapped in 1925."
Sinclair doesn't say much about these little Vauclain compounds, except to describe them as passenger engines. This says more about the type of passenger service available in northern Quebec than the suitability of such a wheel arrangement for hauling voyageurs. It may also reflect a British willingness to use freight-service engines for local passenger trains.
Their HP-LP cylinder pairs were each served by an 11 1/2" (292 mm) piston valve.
They were taken into the Canadian Northern in 1914-1915 and ex-21 eventually was dubbed Canadian National 483. 20 was sold in November 1913 to Inverness Railway & Coal Company on Cape Breton Island."
Soon after the Q&LStJ bought this one Mogul, the railway was rolled into the Canadian Northern in 1906. It kept its original road number until 1912, when it was renumbered 115. The design had plenty of boiler for the cylinder volume with which it was delivered, so it appears that the CNor bored out the cylinders to 20" (508 mm) after 1912.
The Canadian National retained the CNor's class ID but redesignated the 115 as 476.
Carrying its larger firebox over the rear driving axle gave this engine's profile a high-pitched look. Its single truck, shrunken first course, and slender stack look out of proportion with the rest of the locomotive. In March 1922, the cylinders were bushed down from 20" to 18 1/2" in diameter. This extended the locomotive's life only a few years as it was scrapped in July 1925."
Locobase 7971 notes that five of this design were built at the same time for Canadian railways in 1889. The last two went to this western road. In June 1901, the Canadian Northern bought the NP&M and renumbered these 20-21. A later renumbering in 1912 generated the 108-109 that the two carried into the Canadian National in 1920. At that point they took 471-472. 472 was scrapped almost immediately in June 1920, but 471 lasted until June 1927."
These locomotives were delivered as "Richmond" cross-compound. As seen from above, the HP cylinder lay on the left, the LP on the right. The particular feature of a Richmond compound was the siting of the intercepting valve within the steam chest in the LP cylinder. Their original road number order was 872-883, 820-871, 884-893, 795-819, 770-777, 785-794, 778-784. In 1910, the class was renumbered 1203-1214, 1249-1259, 1429, 1260-1274, 1225-1236, 1428, 1237-1248, 1215-1224, 1275-1299, 1309-1316, 1300-1305, 1430, 1306-1308, 1317-1323.
Locobase 13282 shows the class once it was superheated by the Grand Trunk,"
This set of small Moguls came to the CN in small batches; they appear to have been inspired by the McArthur & Company 2-6-0s that also were taken into the railway. Superheating the class led to the use of "economy" valves (piston valves installed in a slide-valve chest).
The C-3-c is shown with works # 44264, which seems early, especially as it had a later road number. The others had numbers 48152-53 and 49905-49906. Toiling on secondary lines, this class lasted until 1954."
Supplied originally to the GTP contractors, JD McArthur & Company, a dozen Moguls went into service after the line was completed. They appear to be quite similar to the slightly later C-3s (Locobase 7968). Some were later fitted with oil burners and tenders holding 2,500 imperial gallons (3,000 US gal) of fuel oil.
As part of the vast Mogul holding eventually operated by the Canadian Northern and other CNR predecessors, this pair came to the railway in 1909. Apparently never superheated, they were withdrawn and scrapped in the late 1930s."
A trio of Moguls for the western Canadian prairies. Purchased by the railway that would be better known after 1908 as the Duluth, Winnipeg & Pacific. Even with that name, the railway didn't connect directly to Winnipeg, let alone the Pacific Ocean. Its Canadian terminus, Fort Frances, Ontario, met the Canadian Northern mainline.
When delivered to the CAR, this was a small Mogul even for the early-to-mid 1880s. The 12/61/665 (as this Mogul was numbered by the CAR) was renumbered 1342 and placed in class E-5 in 1905 when the Grand Trunk took over the former railway. Another renumbering in 1912 generated 2355. And when the CNR took over the Grand Trunk in 1920, it redesignated the 2355 as D-4-b and renumbered it 476. Under that number, its trip to the ferro-knacker in December 1925 was recorded."
This small class came from the CGR's own shops in a variety of configurations. By the time it was numbered 479 in the CN's books, it retained the 17"-diameter cylinders and 180-psi pressure unique to that engine. 480, delivered in 1900, introduced the 18" cylinders but dropped the BP by 10 psi. The last two featured the 18" cylinders and the 180-psi boiler. 479, 480, and 482 had been scrapped by February 1923."
The dozen engines led a very large class of simple-expansion and cross-compound main-line freight Moguls. Grand Trunk followed with thirty two (works numbers 1295-1300 in 1899, 1311-1334 in 1900, and 1347-1348 in 1901). Then came Dickson's five (works numbers 1184-1188 in January 1901), and Brooks's six (works numbers 3752-3757 in February 1901).
The Dickson locomotives, described in "Dickson Grand Trunk Locomotives," Railway and Locomotive Engineering, Vol 14, No 5 (May 1901), p. 203, had 283 tubes and a firebox heating surface area of 186 sq ft (17.25 sq m) for a total heating surface area of 1,951 sq ft (181.25 sq m).
McShane (1899), writing in the cheerleading style of the day, commented of these engines: "we understand that their initial performance gives excellent promise of exceptionally satisfactory results." The data are for the Schenectady locomotives; Baldwin's differ in minor details. Contributing to the firebox heating surface were 15.15 sq ft (1.4 sq m) of water tubes.
1910 renumbering of the class took the road numbers as shown in the specs and assigned new ones in the following order: 1375-1399, 1200, 1400-1412, 1413, 1201, 1414, 1421-1426, 1415-1420, 1427, 1202.
Several in the class were superheated and given 21" cylinders; boiler pressure was reduced to 180 psi.
In 1923, the CNR redesignated the entire class E-7-a and renumbered the engines as follows: 661-673, 708-710, 674-675, 711-716, 735, 717-730, 736, 731, 679-684, 732-733, 676-
678, 734, 750, 737.
This was the first of two later batches of E-class built by Baldwin. The 1907s shown here repeated the basic dimensions of the earlier E class described in Locobase 3152. The ten 1908 locomotives, which were fitted with fewer tubes, appear in Locobase 13281.
This set of Moguls stayed on the Grand Trunk through the transition from the GTP to Grand Trunk Western in 1923. Then renumbered and classed E-7a on the Canadian National in an oddly assorted order: 685, 861, 686, 862, 687-707."
Locobase 3152 and 9069 show the original design of this large class of Moguls, which were built as simple-expansion E or cross-compound Cs. The combined total reached about 260 engines. Many were superheated as shown in the specifications. Some had 22"-diameter cylinders.
Although retirements began in the 1920s, the last locomotives didn't leave service until th late 1940s, and a few hung on until the mid- and late 1950s."
This Mogul's specific identity is partially obscured in all of the roster compilers whose products Locobase has been able to consult (thanks to Raildata's Allen Stanley). The engine is attributed to the Pennsylvania and said to have been built at that railroad's Altoona shops.
But it doesn't match up with either the Pennsy's F1 or F2 (Locobases 1137 and 2837, respectively). Even though the cylinder volume, number of tubes, their diameter and length, as well as the grate areas, are quite close, the lone E-1-a's stated adhesion weight is a full 25 tons (22,680 kg) lower than that of the F2. Also the boiler pressure setting is more more consistent with an 1880-1890 era locomotive.
The roster provided to Allen Stanley by Seth Bramson and originally compiled by Ted McQuinn of Riverview, NB, Canada, shows that the CGR 4571 was the ex-O'Brien, McDougall & O'Gorham (OMO) #25.
OMO were railroad contractors who operated more than two dozen used locomotives. Two of the principals--Michael John O'Brien and Alexander McDougall--also combined with Fowler to form OFM, which is credited with constructing 30% of the National Transcontinental Railway (the core of the Canadian Northern/Canadian National system)."
Grand Trunk went back to Baldwin in 1908 to order a second batch of Moguls based on the 1907 engines described in Locobase 11367. Possibly because the barrel was a bit stuffed with 291 tubes (or because some of them were so low set that they attracted deposits), the new set had 18 fewer tubes (2 rows?). Otherwise, the two sets were identical.
Most of the E-11s were soon superheated; see Locobase 13282.
Among the many dozens of simplified and superheated Moguls converted by the Grand Trunk was this variant, which came on the road as cross-compounds in the early years of the 20th Century (Locobase 9069).
NB: Tube and flue counts are based on conversions in similar-sized boilers with similar tube length. "
Very similar to most other Grand Trunk Moguls, these four went to the D & TSL. Apparently they were never superheated before they were scrapped in 1929.
The small, branch-line Moguls delivered by Kingston in 1910 and described in Lococbase 15655 were refitted with superheater and piston valves in 1913 that supplied larger-diameter cylinders. The result was redesignated E-12.
One example of this class that was taken over by Canadian National as class E-10a was #919, later renumbered as 92 in 1952. 92 was bought for Wilmington & Western (Marshallton, DE) in 1959. See W&W website. Also see http://www.ocsteam.com/96/ (30 May 2003), for the Ohio Central museum railroad, which has a sister locomotive.(#937 in CN service, sold in June 1959. After several private owners, came to the OCRR in 1994. Not in service."
According to the Canadian law website, accessed 13 December 2006, this railway derived from the Quebec, Montmorency and Charlevoix Ry. Co, acquiring its new name in 1889.
This single Mogul served the QRL&P lines until 1953. Although it had relatively small cylinders, the design actually featured a good amount of power from its small drivers and largish grate. "
The Grand Trunk book has the data shown in the specifications. Locobase can find nothing more on this class, except to note that it had the biggest boiler of any Mogul that was incorporated into the Canadian National. Also, it does not seem that these engines were taken in by the CNR.
This sizable class of Moguls was produced by the Grand Trunk as it expanded in several directions. The design itself was relatively small as 2-6-0s went in 1880. A deep, narrow firebox had a small grate but relatively grand direct heating surface area. A large steam dome sat just ahead of the firebox and the middle driving axle.
Retirements began in 1924 and lasted a dozen years, the last engine leaving service in 1936.
Again, this sextet of Moguls was quite similar to the C-3-a and C-5-b shown in Locobases 7968-7969. There's no ready explanation for why the superheater area did not change when the boiler flues were 5" longer, but that may have to do with the Hungersford-Camera superheater employed. This class was retired over a long period, the first going in 1935, the last in 1951."
In the midst of the long run of E-7-a Moguls (Locobase 7981), the Grand Trunk stretched the boiler and enlarged the grate on two of them and came up with the E-7-b. Other than gaining a little more heating surface in the firebox and boiler and enlarging the cylinders by an inch, no major changes were evident.
In the event, no more E-7-bs were built. 864 was scrapped in 1932, 863 in July 1939."
This smaller set of Moguls, which followed the last of the most-numerous E-7s (Locobase 7981) into service on the Grand Trunk three years later, was also smaller in size and power.
Extended smokebox, coned boiler. According to http://www.railwaybob.com/Overview/OverviewPage2.htm (30 May 2003), a Grand Trunk site, this class was built "as part of their program to replace the lighter 4-4-0's and 2-6-0's. Under CNR, these 2-6-0's were used on small branch lines where the track was too light for heavier engines."
Refitted with superheater, more cylinder volume, and piston valves in 1913, redesignated E-12; see Locobase 7982.
NB: The tube count is an estimate based on the known firebox and total evaporative heating surface areas and a calculation of the tube heating surface area."
These two Moguls arrived in 1890. A comparison with several dozen other Moguls of the era (ca 1886-1891) shows this pair have fallen right in the middle of the pack. They served the GTR for more than 30 years. In April 1925, the CNR sold 500 to JR Booth & Company. 499 was scrapped in December 1925."
As part of the CSCE 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. (Keefer had earlier noted that he left government employment in 1852 to help construct the GTR under the guidance of Alexander Mackenzie Ross.)
Wallis's gave the adhesion weight as 84,000 lb (38,102 kg) and engine weight as 99,000 lb (44,906 kg) and the driver diameter as 62"and total heating surface as 1,232 sq ft; boiler pressure amounted to 150 psi. By 1913, when the Grand Trunk's description of locomotives was published, the values had changed to the numbers shown in the specs.
The total number of locomotives shown in this entry refer only to the E3s with the 1,208 sq ft evaporative heating surface. Their road numbers included 2431-2476, 2495, 2517-2526 (Kingston, 1891 - works numbers 409-418)."
Following the 1885 Grand Trunk design of Moguls, this next set had the same number of tubes, but a smaller firebox and grate (but not by much). A few continued serving the CNR into the late 1930s and early 1940s."
See Locobases 9604 and 7980 for the earlier batches of this extensively produced Mogul design. The last ten had a higher pressure boiler with the 1891s engines, longer tubes, and the largest grate of the class."
This set of Moguls followed the pattern of small, light six-coupled engines for the western prairies. The first four came from the Ocean State with 57"(1,448 mm) drivers, the remainder with the 63" wheels shown in the specs.
Several were scrapped or sold before the Canadian National took over the Grand Trunk in 1920. 2372-2373, 2379, 2381 were renumbered 533-536. By that time, the latter two had boilers rated at 155 psi (10.7 bar)."
These three home-built Moguls were rebuilt from earlier locomotives in the late 1890s. They were small and offered power enough for branch lines, but not main line service. Operated on the western prairies, each put in about 25 years of service.
2366 was scrapped in January 1921 before the GT was taken over by the Canadian National. 2367-2368 were renumbered 531-532, but lasted only two years longer before being scrapped in May and November 1923.
Locobase 7971 notes that five of this design were built at the same time for Canadian railways in 1889. The two for the Q&LStJ were headed by the Frank Ross. 13 may have been named Henry Beemer.
The Canadian Northern took over the pair in 1912 and gave them road numbers 110-111. 110 remained with the CNor until that railway was taken over by the Canadian National in 1919. At that point, the CNR renumbered the engine 473, but retired and scrapped in June 1920.
The 13 took a different path because it was sold in 1917 to the Inverness Railway & Coal Co, which gave it #7. The IR&CC operated the 7 until the early 1920s.
