Cumberland & Manchester / Lexington & Eastern / Louisiana & NorthWest / Louisville & Nashville 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 10 / 150 (Locobase 6133)

Data from 1918 USRA diagram book of L&A locomotives supplied by Allen Stanley in March 2004. Works numbers were 24805, 24835 in November 1904.

The Consolidation pair described here had very small drivers and a low axle loading, although their boilers was reasonably proportioned with reference to the cylinder volume.

After only 6 years with the L & NW, 10 was sold to the Louisiana & Arkansas logging road. In June 1922, the L & A sold the engine to the Grace Logging Company in Missouri.

#11 remained on the road until 1923 when it was sold to locomotive rebuilder/reseller Southern Iron & Equipment.. Proving to be something of a boomerang locomotive, 11 started its volley when SI & E sold it almost immediately to the Gainesville Midland as their 102, but that short line returned the engine before the year was out. SI & E next tried with Fountain Campbell Lumber Company of Ladysmith, Wisc as the #4, but that logger returned the 4 in March 1924. 4 remained with SI & E until 1927, when the reseller sold it to Bissell Lumber. Bissell held on to the 4 for 8 years before selling it directly to the Roddis Lumber & Veneer Company of Park Falls, Wisc in 1935.


Class 170 / H-2 (Locobase 9813)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 3499, 3502, 3507, 3510, 3512-3513, 3609-3614, 3621-3622, 3625-3631, 3645-3648, 3654-3657, 3666-3671

This was a big class of medium-sized Consolidations. Almost all of them were later rebuilt as Class B-6 0-6-0 switchers. By the 1920s, only the 631-632 were still arranged as 2-8-0s.


Class H-10 (Locobase 9822)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

When the L & N went back to Rogers two years after it took delivery of the H-9s (Locobase 9821), the Paterson, New Jersey builder produced a larger boiler with fewer but longer and larger-diameter tubes. Otherwise, the power dimensions and grate were essentially unchanged, although the boiler pressure climbed and the firebox continued to add direct heating surface.


Class H-12 (Locobase 9823)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Locobase doesn't know for sure who built these locomotives or when, so both "Rogers" and "1897" are estimates. Comparing this H-12 to the H-10 from 1895 (Locobase 9822), however, suggests that the H-12 simply continued the Rogers design in most respects. Changes included a longer-stroke cylinder that actually reduced total volume slightly but made more use of each "lungful" and adding 22 small tubes to the boiler. Two other locomotives in this inferred batch saw still more changes; see Locobase 9824.


Class H-13 (Locobase 9824)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Inferring from other evidence that these were Rogers engines of 1897 (like the H-12s described in Locobase 9823), Locobase notes that this pair differed from the H-12 in two important respects: a larger cylinder diameter and drivers standing 3" taller. Thus, the design developed more tractive effort while gaining some useful speed capability (relatively speaking, of course).


Class H-14 (Locobase 9825)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Continuing in a speculative vein, Locobase contends that this class fills out the batch ordered from Rogers in ca. 1897 (see H-12 in Locobase 9823, H-13 in Locobase 9824). This class combines the 52" drivers of the H-12 with the larger cylinders of the H-13.


Class H-15 (Locobase 8138)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

According to a compilation of Richmond locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, works numbers were 2642-2651.

This class of Consolidations operated until 1928-1934.


Class H-16 (Locobase 2620)

Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899), supplemented by L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 3021-3035 in August 1898.

The Brooks Catalogue's data is shown in the specifications; the L & N's 1927 is slightly different. This engine's most singular physical feature is the clerestory cab. Otherwise it's a relatively standard Consolidation with Improved Belpaire boiler and a fair number of large-bore flues.

After seeing a few go to the scrapyard in 1928-1930 (891, 896, 888 respectively), the class approached extinction in 1933 when all but one of the rest were retired including nine on 30 September. Class leader 885 survived until 2 April 1934.


Class H-17 (Locobase 8139)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers 2870-2878 in 1899.

A nonet of Consolidations followed immediately Brooks's H16 locomotives (Locobase 2620). They had only detail differences from the Dunkirk, NY builder's engines.

Like those engines, these were scrapped in the late 1920s, early 1930s with most being dismantled in September 1933.


Class H-18 (Locobase 3936)

Data from "Cooke Consolidation for the Louisville & Nashville", Railroad Gazette, Volume 32, No. 4 (26 January 1900), p. 55; corrected and supplemented by L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 2497-2501 in January 1900 and 2556-2565 in July.

Very similar to the Brooks engines delivered in the same year. The drivers are slightly smaller and the boiler has two more tubes. As delivered, the boiler pressed 170 ps (12.07 bar), the firebox heating surface measured 188 sq ft (17.47 sq m), grate area 28.4 sq ft (2.64 sq m), and total heating surface 2,022 sq ft (187.85 sq m). The data in the specifications come from 1927..

This class of Consolidations operated until 1928-1934.


Class H-19 (Locobase 9826)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

In its brief incarnation as "International Power", this Ocean State builder supplied 10 Consolidations that followed the design delivered by Cooke in the same year, but used 2" tubes instead the 2 1/4" of the Cookes. The result was less heating surface and a higher boiler demand factor.

Some members of this class remained in service until 1949.


Class H-20 (Locobase 9827)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Cooke works numbers 2720-2729.


Class H-21 (Locobase 9766)

Data from Angus Sinclair, Railway and Locomotive Engineering, Vol XV, No 8 (August 1902), p. 366..

Turn-of-the-Century Consolidations with Belpaire fireboxes and a further increase in heating surface.


Class H-22 (Locobase 8140)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 2879-2880 in 1899.

This pair of Consolidations followed immediately Richmond's H17 locomotives (Locobase 8139) and were H17s with a longer piston stroke and slightly higher boiler pressure.


Class H-23/H-23A (Locobase 9828)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

The chief difference among the locomotives in this large class was the provision of Walschaert valve gear in the H-23A vs the Stephenson link motion that had been standard up until then. The design still seems to have been more evolutionary, featuring a modest increase in driver diameter,adhesion weight, grate area, and evaporative heating surface. Firebox heating surface included 14 sq ft of arch tubes. None of the H-23 class was ever superheated.

It was a busy time for one of the biggest locomotive firms in the world and the Baldwin works filled two orders from the L&N in singles and pairs interspersed among engines meant for dozens of other customers then on the books.

Baldwin delivered the first 20 (22552-22553, 22584-22585, 22597, 22609-22611, 22634-22635, 22655-22656, 22683, 22697, 22781, 22799, 22858, 22868, 22920, 22925) in July-October 1903. Rogers or the L & N shops themselves contributed the next 5. Then Baldwin supplied the next 35 (22965, 22990, 23011, 23026, 23030, 23036-23037, 23065

23070, 23095, 23100, 23120, 23131, 23138, 23150, 23160-23163, 23172, 23175, 23178, 23197-23200, 23211, 23218, 23227, 23244, 23254-23255, 23263-23264, 23271) in October-November 1903.

92 more came from the L & N's own shops. And finally Baldwin finished off the H-23 class September 1906 to April 1907 with 55 more (29077-29078, 29095-

29097, 29135, 29156-29157, 29180, 29192, 29208, 29234-29235, 29252, 29258, 29261, 29280, 29317-29319, 29345, 29387, 29412-29413, 29427, 29459, 29503-29504, 29535, 29556, 30072, 30081, 30090-30092, 30176-30177, 30223-30224, 30255-30256, 30306-30308, 30343- 30344, 30362, 30377-30379, 30484-30485, 30500, 30533, 30602)

Baldwin's H-25s, which were identical except for the adoption of piston valves, are shown in Locobase 16171.


Class H-24 (Locobase 9829)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

It's not clear why Rogers would have supplied this pair of small Consolidations in 1904, except perhaps to address a particular need for a light-footed, branch-line 2-8-0. Whatever the reason, the two engines remained in service essentially unchanged (except for the addition of 14 sq ft of arch tubes to the firebox) until their retirements in 1947 (849) and 1948 (848).


Class H-25 (Locobase 16171)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 32593, 32622-32623, 32648, 32654, 32658-32659, 32712 in January 1908.

After H-23 Consolidations had been built by several manufacturers from 1903-1907, Baldwin produced this octet in the middle of run of Rogers and the L&N-shop products. Possibly the piston valves made it easier to consider superheating the class, for most of these soon received the installation. See Locobase 9830.


Class H-25A - superheated (Locobase 9830)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Like most of the early 20th Century North American locomotives delivered as saturated engines, this class (Locobase 16171) was soon provided with a superheater. The H-25A variant was essentially identical to the H-25 except for the drier steam. The H-25B (Locobase 9830) had larger cylinders.


Class H-25B - superheated (Locobase 9831)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

As with the H-25As (Locobase 9830), the most significant change to the H-25 design (Locobase 16171) was the addition of the superheater. The -25Bs received cylinders that measured just 1/2" more in diameter, but that difference provided a noticeable boost in starting tractive effort. Otherwise, the design was essentially as delivered in the early part of the 1900s except for the addition of 14 sq ft (1.3 sq m) of arch tubes to the firebox. Several H-25As were later refitted as -25Bs and the entire class operated into the late 1940s.


Class H-26 (Locobase 9832)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Like the H-24s from Rogers (Locobase 9828), this pair of Virginians ran outside of the large class of standard Consolidation. For these two, however, the direction was bigger, not smaller. They pressed heavily on the rail and had larger boilers than the H-23 and H-25-series engines with many more tubes.

Unlike the big-production series, the H-26s were never superheated and went to the ferro-knacker's yard in 1940.


Class H-27 (Locobase 9833)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Continuing the production of the basic Consolidation, the H-27s offered the one difference of a 2" longer stroke, which put them in the league of most 2-8-0 fleets that had entered service in the previous decade. Like the others, these engines were delivered with Walschaer radial valve gear and piston valves.

Baldwin produced the first 25 (35029-35033, 35069-35077, 35116-35119, 35152, 35217-35222) in August & September of 1910 and the L & N added the balance.


Class H-27A - superheated (Locobase 9834)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Once the H-27s were in service (Locobase 9833), the railroad began to superheat them. The upgrade mirrored the makeover applied to the H-25s (Locobase 9830), except that the boiler tubes and flues were 2" longer and the weights somehow came out 3,000 lb less. As with the other class, the firebox heating surface now included 14 sq ft of arch tubes.


Class H-27B - superheated (Locobase 9835)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Superheated H-27s followed the H-25 superheating pattern and came in two flavors: Those with the 21" cylinders (Locobase 9834) and the locomotives in this entry, which either replaced the original cylinders or bored them out 1/2". In the process, the design gained over 2 tons of weight, which was more evenly spread over the 4 adhesive axles. The firebox received its 14 sq ft of arch tubes as well.

So equipped, these medium-sized freighters served the L & N for decades, some lasting into the 1950s.


Class H-28A (Locobase 9836)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

With the production of these Consolidation at its own South Louisville shops, the L & N hit on the formula for substantial hauling power. Retaining the 57" drivers suitable for its undulating profile, the railroad adopted bigger cylinders and fed them with a much larger grate (although the firebox heating surface area increased by only a few square feet thanks to the 20 sq ft of arch tubes). Both the tube and flue diameters increased and the number of each grew as well.

The result was a heavier locomotive (just under 100 tons adhesive weight) with lots of starting tractive effort. As Charles B Castner notes in Drury (1993), long-standing weight limits on many bridges made these and the H-29s the top-end power for fast freights into New Orleans into the 1940s.


Class H-29 (Locobase 9837)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

The L & N's large Consolidation program begun with the H-28A in 1911 (Locobase 9836) continued in 1912 with the H-29. The only difference was the railroad's ability to strip about 7,000 lb out of the design. All other dimensions remained the same.


Class H-29A (Locobase 9838)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

In producing the last 25 locomotives of the large-Consolidation design that entered service as the H-28 in 1911 (Locobase 9836), the shops increased cylinder diameter by 1/2" more. An accompanying increase in weight kept the factor of adhesion at just about 4. This was the final batch of 2-8-0s and they served the L & N until the end of steam.


Class H-3 (Locobase 9814)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

An unusual feature of this low-drivered drag-freighter was the considerable gap between the first driven axle and the second. Locobase isn't sure why such a spacing would have been adopted. According to Gene Connelly's L&N Roster, all but the 640 and 647 were converted to 0-6-0 switchers.


Class H-30 (Locobase 9839)

Data from L&N 5 1941 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

It's surprising to see a Consolidation pair being built so late in the era, but both Castner (in Drury, 1993) and the L & N diagram books insist on the 1921 construction date. The locomotives had the usual accoutrements of arch tubes (which added 18 sq ft to the firebox heating surface), superheat, and power reverse.


Class H-4 (Locobase 9815)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 1981-1988 in 1888.

Like the H-3 built by the L&N and shown in Locobase 9814, this Consolidation had a large gap between the first driven axles. The Rhodie's design differed in having a larger firebox. They were later renumbered in this order: 650-651, 656-658, 654-655, 649, 652 and all were converted to 0-6-0 switchers.


Class H-5 (Locobase 9816)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 3856, 3858, 3863, 3876, 3881-3883, 3889-3890, 3893, 3899 in 1887.

Very similar to the Consolidations buillt by the L&N at the same time (Locobase 9814), but possessing more firebox heating surface area and slightly more cylinder volume. Four--700, 703, 705, 709--would still roll as 2-8-0s in the 1920s. The other six had been converted to 0-6-0 switchers.


Class H-6 (Locobase 9817)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

This class repeated the standard L&N Consolidation power dimensions (20" x 24' cylinders, 150 psi, 51-52" drivers), but rolled out under larger boilers and bigger grates. A few later had their cylinders bored out to 21" with the results showing in the specifications.


Class H-7 (Locobase 8143)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

According to a compilation of New York/Rome locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, works numbers for 351-366 were 652-667 (October-December 1890)

Much of this class's heating surface could be found in its firebox, relatively speaking. While the boiler was only of average size for a Consolidation of the late 1880s, the firebox was one of the largest around. Its low drivers and high adhesion weight meant a strong-pulling 2-8-0.


Class H-8 (Locobase 9818)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Cooke works numbers 2169-2185.


Class H-9 (Locobase 9821)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.


Class H0 (Locobase 9811)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 23, p. 12. Baldwin works numbers included 17680 in April 1900, 18751 and 18818 in March 1901, 20014-20015 in (January 1902, 22966-22967 in October 1903, and 23402 in December.

The L&E came under Louisville & Nashville control in 1910, but continued to operate independently until 1915. This entire class retained its original configuration until scrapped, although updates enlarged the firebox by 19.7 sq ft (1.85 sq m), most likely through the addition of arch tubes.

659-660, 664-665 were scrapped in July 1933. The other half of the class lingered well into the late 1940s: 661went to the ferro-knacker in December 1948, 662 followed almost a year later in November 1949, 663 in March 1950, and 666 remained in service until March 1952.
