Class 1 (Locobase 2634)

Data from 1899 Brooks Catalogue.

Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004.

Works #2841

Apparently this narrow-gauge line's first locomotive, a modest little Mogul.

Class 4 (Locobase 6751)

Data from C & S 7 -1939 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

The Union Pacific, Denver & Gulf was the first system to own these 10 small Moguls as numbers 109-116, 107-108. The C & S took over the UP, D & G in 1899 and renumbered them as shown in the specs.

The 2-6-0s had a decent amount of power for their size. (In fact, they seem to have been among the most potent among the saturated-steam 2-6-0s that ran on narrow gauge anywhere.)

And they obviously filled a light-rail passenger-service niche as the first to be scrapped (the last built) only went to the ferro-knacker's yard in October 1929. Three more followed in the 1930s. #9, retired on 31 May 1941, was restored to service in 2006.

Class B-3-M (Locobase 7364)

Data from the Wichita Valley 1 - 1915 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

These two Moguls were the freight power of the Wichita Valley.

Six more 2-6-0s came to the WVR from the railway's new owner, the CB & Q, in 1909. They were built a couple of years after the current pair and were part of a large class on the Burlington Route; see Locobase 5460. On the WVR they were classed B-3-N.

Class H (Locobase 9717)

Data from Angus Sinclair, "Ratio of Heating Surface to Grate Area and Cylinder Volume," Railway and Locomotive Engineering (Volume 10, 1897), pp. 316-318. See also

data from a locomotive diagram published on Vernon Beck's website -- http://home.earthlink.net/~vnlbeck/H/h.tif (accessed 22 March 2003). Locobase 5457 has the compound version.

Locobase is positive that this is the simple-expansion version of the H Compound found on Vernon Beck's site. Problem is - there's no reference to the H in an extensive roster.

Class H Compound (Locobase 5457)

data from a locomotive diagram published on Vernon Beck's website -- http://home.earthlink.net/~vnlbeck/H/h.tif (accessed 22 March 2003).

Several elements are puzzling about this design. It has 69" drivers, considerably taller than other Burlington Moguls. The boiler diameter is similar to others, but it has 2 1/4" tubes that are relatively short. Its grate area is larger than most of the others, and, at least at the time the diagram was prepared in the early 1900s, the boiler was pressed to 180 psi. (Like the other Burlington Moguls, the design had a Belpaire firebox.)

All in all, this engine seems to be derived from the H-1 (Locobase 5460), but it's a later conversion, possibly to test the cross-compound idea.

Class H-1 (Locobase 5460)

data from a locomotive diagram published on Vernon Beck's website -- http://home.earthlink.net/~vnlbeck/H/h1.tif (accessed 22 March 2003).

Obviously a popular design.built by the Burlington in several locations, Baldwin, & Rogers.. According to Corbin & Kerka (1960), this class had Belpaire fireboxes mounted above the frames and came with two diameters of drivers -- the 68" shown here and 62" drivers. A series of 1892 tests run by the Burlington on several types of locomotives included one of each size of H-1 Mogul. Per horsepower, the H-1/68" consumed 5.76 lb of coal and 32.9 lb of water. Overall, the 68" variant was more economical with trains of 10 cars or less, the 62" coming first with longer trains.

The Wichita Valley purchased 8 of these in September 1909 as their 11-18. Retirements from the CB & Q began in the 1920s and continued through the decade.

Class H-1C (Locobase 5458)

See also data from a locomotive diagram published on Vernon Beck's website -- http://home.earthlink.net/~vnlbeck/H/h1c.tif (accessed 22 March 2003).

Obviously a popular design.built by the Burlington, Baldwin, Rogers, and the railroad's own Auburn shops. The diagram shows a late 19th-century engine with a deep firebox, dome over the last course, uneven separation between the driving axles.

Class H-2 (Locobase 5461)

See also data from a locomotive diagram published on Vernon Beck's website -- http://home.earthlink.net/~vnlbeck/H/h2.tif (accessed 22 March 2003). Firebox heating surface includes approx 16 sq ft (2 3 1/2" diameter, 9' 8 3/4" long) arch tubes.

A follow-on design from 1887's H-1 (Locobase 5460), but with a relocated steam dome, shallower firebox, larger dimensions. Most were built by Rogers, although the later engines came mostly from the Burlington's own shops and from Pittsburgh. The latter's works numbers were 1815-1828 (May-July 1898)

Class H-2 (compound version) (Locobase 5459)

See also data from a locomotive diagram published on Vernon Beck's website -- http://home.earthlink.net/~vnlbeck/H/h2u.tif (accessed 22 March 2003).

Obviously an enlargement of the H Compound (Locobase 5457)with bigger cylinders, more weight on the drivers, and a larger boiler. According to Corbin & Kerka (1960), this was the lone cross-compound example of the H-2 Moguls (Locobase 5461). Like the rest, it used a Belpaire firebox.

Class H-3 (Locobase 7692)

Data from CB&Q 3 -1953 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

The first 10 of this Mogul class were built at Burlington's West Burlington shops. Seven o of the next 8 were produced in Aurora (nearer Chicago) with 1214 also coming out of West Burlington.

All enjoyed at least 30-year lifetimes and were retired soon after reaching that milestone.

Class H-4 (Locobase 2607)

Sizable Moguls delivered over two years by Baldwin, Rogers, and the Burlington's own shops. Firebox heating surface included 16.2 sq ft (3 1/2" diam, 9' 10 1/2" long) of arch tubes.
