Data out of List & Description of Southern Railway Locomotives (1914) book provided in April 2004 from Allen Stanley's extension collection. Narrow-gauge consolidations delivered in 2 different years (1886 - works #8038, 1888 - 9140) with the only difference being the slightly higher boiler pressure (135 psi vs 130) in the later engine.

Class 133 (Locobase 6502)

Data from Allen Stanley's collection of locomotive diagram books. This class was shown on the Southern's 1914 locomotive summary tables. Also Prince (1965).

The first five -- works #2009-2013 -- were among the first of the 20 x 24 Consolidations that the Southern system predecessors bought in large numbers in the 1880s and 90s. The Knoxville & Ohio took delivery of 5 more in 1886 with identical dimensions.

After the Southern's adoption of the 10-engine class, they ran on for another 30 years except for 165, which was scrapped in July 1915. Two -- 133 & 136 -- were sold in January 1925. 135 went in March 1926, 168 in April 1929, 136 in August 1929, 134 in September 1932, and the remainder -- 164, 166, 167 -- in October-November 1933.

Class 138 (Locobase 6488)

Data from Data from Allen Stanley's collection of locomotive diagram books. This class was shown on a diagram dated July 18, 1913 and 1914 locomotive summary tables..

These were repeats of the Baldwins of 2 years earlier, although they put almost 12,000 lb more on the drivers. Schenectady works #2902-2909 (1889) and 2897-2901 (1890). According to Prince (1965), the latter originally ran on the Knoxville & Ohio, a Kentucky road. All were taken into the Southern in the 1890s.

Class 146 (Locobase 11149)

Data from Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 156-157. Works numbers were 3098-3101 and 3110-3123.

Class 267 (Locobase 6508)

Data from Allen Stanley's collection of locomotive diagram books. This class was shown on the Southern's 1942 locomotive summary tables. Also Prince (1965).

Baldwin's works #7103 wound up on the Carolina & Northwestern by 1942, but Locobase hasn't traced its history yet.

Class 411 / G (Locobase 5147)

Data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002). Works numbers were 8767-8768, 8770-8771, 8774-8775, 8795-8797, 8802 in September 1887; 8866, 8868-8869, 8873 in November; 9009, 9011-9012 in January 1888; 9044, 9046, 9049, 9050, 9054, 9058-9059 in February; 9578-9581, 9590 in October.

One of the lightest Consolidations to be inherited by the Southern Railway as it absorbed the ETV&G in 1894, this relatively numerous class provided secondary-line service for decades, in a couple of cases until 1949. A few were sold to other railroads in the interim, including the last one built to the Augusta Northern in March 1933.

The later career of the 8869 (107) began with its sale to the eastern Tennessee line Smoky Mountain Railroad (completed much earlier as the Knoxville, Sevierville & Eastern) in May 1942 as their 107. After the KS & E closed in 1962, the 107 was sold to the Rebel Railroad and operated in tourist service through the time that the Rebel was incorporated into the Dollywood amusement park. As of 2009 it stood at the entrance of Dollywood

Class 440 / G (Locobase 11075)

Data from SRY 1910 List & Description of Locomotives supplied in March 2004 and SRY 5 - 1929 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 9582-9585, 9587 in October 1888.

After Baldwin had delivered 27 of the 20" x 24", 50" driver Consolidations to the ETV & G, they changed the boiler layout to hold fewer, larger-diameter tubes, enlarged the firebox slightly, and produced 5 more.

After more than 35 years of service, 130 and 131 were scrapped in September 1923. 128 followed in December 1928, then 129 in April 1931. 132 somehow escaped recycling until March 1939.

Class 458 (Locobase 5148)

Data from Southern Railway diagrams hosted on http://www.southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002). Works numbers were 3098-3101, 3110-3123.

Repeats of the previous year's Schenectadies (Locobase 6488), these ETV&G engines had shorter, sharply coned boilers and a few more tubes. When absorbed by the Southern in 1894, they continued on in their secondary-line duties until scrapped one by one.

Class 500 (Locobase 6493)

Data from locomotive diagram book provided from Allen Stanley's extension collection (diagram 22-F-22, dated August 2, 1910). Works numbers were 7663-7664, 7666, and 7670 in August 1885; 7962 in May 1886; 7966, 7969-7971, 7982-7985, 7988, 7991, 7995, 7999, 8003, 8005 in June; 8101, 8103 in August.

This large class of R & D locomotives were smaller than the Richmonds described in Locobase 6010, but had 2 1/4"-diameter boiler tubes. The first four were delivered for operation on the 5-foot gauge, but were soon converted to standard gauge.

Class 516 (Locobase 6010)

Data from Evaporative heating surface information from locomotive diagram book provided in April 2004 from Allen Stanley's extension collection

Class 521 (Locobase 6500)

Data from 1914 List of Locomotive Descriptions and Specifications provided in April 2004 from Allen Stanley's extension collection and Prince (1965). Works numbers were 8333-8334.

Although right in line with the other Consolidations bought by Southern subsidiaries at this time, these had somewhat bigger boilers.

Class 523 / G (Locobase 6501)

Data from 1914 List of Locomotive Descriptions and Specifications provided in April 2004 from Allen Stanley's extension collection and Prince (1965). Works #8772-73, 8789, 8785, 8920-8923, 8963, 8965.

Basic Southern design -- almost regardless of builder. This class had a slightly lower adhesion weight.

Class 544 / G (Locobase 6498)

Data from 1914 List of Locomotive Descriptions and Specifications provided in April 2004 from Allen Stanley's extension collection and Prince (1965). Richmond works #1915-1916, 1919, 2018-19, 2045-47, 2119 delivered in 1889-1890.

Class 546 (Locobase 5144)

Data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002). Works numbers were 2394-2397.

Consolidateds for one of the principal components of the Southern when the latter was formed on 1 July 1894 through a shotgun marriage imposed by JP Morgan. #7 proved particularly durable, not being scrapped until 1950.

Class 55 (Locobase 7619)

Data from WP 2 - 1946 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. The Western Pacific-oriented history site http://www.wplives.com/motivepower/srosters/Class_124_Roster__/class_124_roster__.html and http://www.tidewatersouthern.com/contents/motivepower/steam/280WP124/280wp124.htm, both accessed 3 July 2006 for the history of the engine.

This Baldwin Consolidation (works# 6085) had several owners. Noting that the C, NO & TP was not regauged from 5 feet to the standard gauge for 5 years after the 55 was delivered, the Tidewater Southern historian speculates that 55 may have delivered on the broader gauge. After more than 20 years of service bearing 3 engine number, 589 went to the Boca & Loyalton in California in 1905 as that railroad's #5. The B & L was incorporated in 1900 to serve the lumbering area encompassed by Truckee, Boca, Loyalton and other Sierra Valley towns. The WP bought the railroad in 1905, apparently because it would simplify supporting the Feather River Canyon construction over the next several years. In 1916, the 5 became the WP's 124.

Class 555 (Locobase 5145)

Data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002).

A Baldwin batch virtually identical to the Rhode Island engines supplied to the R&D in the same year. Unlike the Rhode Islands, though, all of these had been scrapped by the mid-1920s.

Class 560 (Locobase 6009)

Data from Evaporative heating surface information from locomotive diagram book provided in April 2004 from Allen Stanley's extension collection

Consolidateds for one of the principal components of the Southern when the latter was formed on 1 July 1894 through a shotgun marriage enforced by JP Morgan. #7 proved particularly durable, not being scrapped until 1950.

Class 586 (Locobase 6499)

Data from 1914 List of Locomotive Descriptions and Specifications provided in April 2004 from Allen Stanley's extension collection and Prince (1965). Richmond works #1915-1916, 1919, 2018-19, 2045-47, 2119 delivered in 1889-1890.

Class 68 (Locobase 11411)

Data from "Locomotive Building" Railroad Gazette, Vol XLIII, No 1 (5 July 1907), pp. 26. Works numbers were 41119-41122 in 1906, 44445-44447 in 1907.

Strictly speaking, the data for this entry refer to the 3 locomotives delivered in 1907. But a comparison of Prince's Southern Steam Locomotives and Boats (Green River, Wyo: Richard E Prince, 1965), p. 179 and later Southern Railway descriptions of locomotives (1926, e.g.) show that the two batches were essentially identical.

Presumably that continuity extended to the "special equipment" shown in the 1907 article, but at least in 1907, some of the component suppliers for Schenectady were:

Air-brake Westlnghouse

Boiler check Phillips

Boiler lagging Johns-Manvllle

Injector Nathan simplex

Lubricators Franklin

Piston rod packing United States

Valve rod packing United States

Safety valve Crosby

Sanding devices Coates

Sight-feed lubricators Nathan Bull's-eye

Steam gages Crosby

Tires—driving wheel Latrobe

Tthe 1926 list shows the 1907 engines with 2,140 sq ft of evaporative heating surface. Because these lists did not include superheater area and because the 1926 list shows the 1906 locomotives with 2,558 sq ft (5 sq ft difference from the 1907 "class"), Locobase concludes that 1) the 1906 engines were not superheated, and 2) the 1907 engines were.

All three ran into the 1930s before being scrapped or sold in 1935-1936.

Class D / D1 (Locobase 6109)

Data from the 1912 Alabama Great Southern locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive collection.

The first of the AGS Consolidations (works #3045-3050), these were better-suited than the Moguls to mainline freight duties. They had taller drivers, more ample steaming capacity, and higher tractive effort. The D1s (126-129 - works #3309-3312) followed two years later. There's no indication from the diagrams of any differences between the two classes.

Five of these locomotives were sold to the Nashville, Chattanooga & St Louis as their class H-4C-28, road numbers 335-339.

Class D-9 / K (Locobase 5699)

Data from table in the June 1908 AERJ. Alco-Richmond's works numbers were 30971-30975 in 1905, 40113-40117 in 1906, and . Baldwin works numbers were 31540-31542, 31606, 31614, 31625-31628 in August 1907; 31674-31676, 31689, 31724-31726, 31748-31749, 31798-31800 in September; 31850-31851, 32028-32029 in October; 36442-36447, 36498-36501 in April 1911.

Class D2 / H-7 (Locobase 6110)

Data from the 1912 Alabama Great Southern locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive collection. Works numbers were 21217-21219 in November 1902.

The Baldwin version of the basic AGS Consolidation had more cylinder volume, slightly longer tubes and slightly larger grate, but a shallower firebox. They were delivered in a batch. When the Southern Railway renumbered, these were grouped with the later group as H-7. Retirements occurred over several years - from 1924 to 1938.

Class D3 / H-7 (Locobase 6111)

Data from the 1912 Alabama Great Southern locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive collection. Works numbers were 21645, 21665, 21669 in February 1903 and 21733 in March.

A year after producing its first batch of Consolidations for the AGS, Baldwin added 4 more (BLW Works#). These locomotives had substantially larger -- namely wider -- grates; the width went from 41" to 66". Overall heating surface didn't change much at all.

When the Southern renumbered, this quartet was grouped with the previous year's engines as class H-7. Retirements occurred over several years - from 1924 to 1938.

Class D9 / K (Locobase 6112)

Data from the 1912 Alabama Great Southern locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive collection.

This was the standard 2-8-0 on the Southern Railway System in the first decade of the 20th Century. The 31 shown here on the AGS differed only in tender size. What's puzzling to Locobase is the very small firebox heating surface, although the grate area is sizable enough.

Deliveries came in batches, as follows:

Year Builder Works# Road #

1905 Richmond 30980-30987 190-197

1906 Richmond 40647-40650 198-201

1907 Richmond 42903-42908 202-207

1909 Baldwin 33696-33699, 33709-33711, 33721-33722 in August 1908 208-216

1909 Baldwin 33730-33733, 33795 in September 1909 217-221

All were reclassified as K. Many were superheated and reclassified Ks. As might be expected for so ubiquitous a machine, retirements spanned decades.

Class F / Hs-6 (Locobase 6094)

Data from the 1917 New Orleans & North Eastern locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive collection. Works numbers were 34906-34907.

A pair delivered together in 1910 to Hodges Downey Construction, these two long-stroke Consolidations were bought by the NO & NE in 1912. Later superheated. In the Southern renumbering, they became 6898-99 and as such slogged along at the head of drag freights for another 33 years. Both were retired in May 1949.

Class G (Locobase 5146)

Data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002). Works numbers were 11029 in June 1890; 11031, 11052, 11056-11059, 11064, 11068, 11070-11072, 11081 in July; and 11314-11317, 11319 in October (they were later numbered 68-72).

Identical to the Baldwins that went to the Richmond & Danville in the same year (Locobase 5145). Disposals began in the 1920s and continued one at a time into the 1940s.

Class G-1 (Locobase 6484)

Data from Allen Stanley's extensive collection of diagram books and locomotive summary tables. The diagram is dated October 30, 1926.

These Consolidations were delivered in 1892-93. The class came into the Southern in 1900 from the LE & StL as a block. Most were sold for scrap in August 1923 with 104 & 108 lasting until 1928.

Class G-2 (Locobase 2632)

Data from 1899 Brooks Catalogue and from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002).

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 #2671-76, produced in June 1896.

A relatively light Consolidation, this class retired between May 1927 (200) and November 1947 (191) with most out of service by World War II.

Class G-2 (Locobase 5137)

Data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002).

These are the G-2s described by Prince (1965) as having been delivered by Richmond in 1895-96. In 1903, the G-2s were renumbered 179-200. A relatively light Consolidation, this class retired between May 1927 (200) and November 1947 (191) with most out of service by World War II.

B Rumary's summary of Richmond production, supplied by Allen Stanley in March 2004, showed 2371-2381 and 2391-2395.

Class G-4 (Locobase 2652)

A big clutch of Consolidations came to the Southern when it absorbed these CNO&TP locomotives. Rhode Island built 36, Baldwin 31, Pittsburgh 10, and Schenectady 2. Predecessor class IDs included class D6 and D7.

They were scrapped between 1922-1929.

Prince (1965); data from CNO&TP MB 1917 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Class H (Locobase 6482)

Data from Allen Stanley's extensive collection of diagram books and locomotive summary tables. 1914 Southern Railway locomotive summary and Nov 7, 1913 diagram.

This batch of Consolidations (works 2675-2679) were very similar to 10 delivered in the same year from Richmond and described in Locobase 3287. This quintet had slightly smaller cylinders, however, and a larger boiler.

Class H-1 (Locobase 5139)

Although classed and numbered below the H-2s, these appear to be follow-ons to that design. Data also from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002).

More chaos in numbering is apparent from the Prince (1965) roster, in which the first Richmond engines were delivered in 1899 and numbered 262-269 (works #2906-13 ), later 275-282. Then came the 238-239 (works #3018-9) in 1900 (later 250-251), immediately followed by 277-299 (3020-3042) and by 400-409 (3124-3133) in 1901. These later engines were later renumbered 290-322.

The principal changes were a slight lengthening (7") of the firetubes and the mounting of taller drivers. The latter alteration undoubtedly enhanced the design's ability to undertake mixed-train service and the class was built in relatively large numbers.

Baldwin chipped in 25 more of the same design (with slightly different specs) in 1901; see Locobase 11076.

Most of the class was scrapped in the 1930s, although many of the 1901 batch survived World War II.

Class H-1 (Locobase 11076)

Data from SRY 1910 List & Description of Locomotives supplied in April 2004 and SRY 5 - 1929 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 19602-19609 in October 1901; 19685-19688, 19731, 19749-19753, 19768-19769, 19774-19778 in November.

Virtually identical to the Richmond-built H-1s (Locobase 5139), this Baldwin product had slightly less firebox heating surface and weighed more.

Most of the class was scrapped in the 1930s, although 362 ran its string beyond World War II before being dismantled in February 1949.

361 was sold to the Cumberland Railway sometime after 1905. The CR sold 361 to the brand-new Artemus-Jellicoe Railroad connecting Artemus, Ky and Jellicoe, Tenn in July 1924. The AJR scrapped the 361 in April 1937. 363 found a second career on North Carolina short-line High Point, Randleman, Asheboro & Southern. 370 was bought in Octobetr 1933 by the Mexican railroad Nacional de Tehuantepec.

Class H-2 (Locobase 3287)

Data from Railroad Gazette, Vol XXX, #9 (1898). (Some data also from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002). Works numbers were 2731-2738 in 1898.

Locobase took one entry (this one) and split it into two, the other being 11071. His thinking ran as follows: The 1910 descriptions and the 1929 diagrams show only that 18 locomotives were combined as a single class with the sole difference apparently being the tender capacity. But when that data was compared to the 1898 article, there was a small difference in grate and firebox areas that would account for the disparity in heating surface. Supposing that the larger firebox would have come a year later, Locobase assigned the 1897 batch to 11071 and the 1898 batch to this entry.

Class H-2 (Locobase 5138)

Data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002). Works numbers were 16162-16165 in August 1898.

The only H-2s not built by Richmond, these four Consolidations followed the design closely.

Like the others, three of these engines served into the mid-1930s while the 272 ran until November 1952.

Class H-2 (Locobase 11071)

Data from SRY 1910 List & Description of Locomotives supplied in April 2004 and SRY 5 - 1929 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 2626-2635 in 1897. (258-261 from Baldwin probably also had the same specifications.)

This was a batch of 10 locomotives supplied to the Southern in 1897; The 248s were renumbered 253-262 in 1903. They were a good size and soldiered on into the 1930s. The first was scrapped in November 1933 and the others followed in the 1930s, except for 260 (old 247), which was retired in September 1949.

Class H-3 (Locobase 5150)

Data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002).

This group of Consolidations had larger fireboxes, but were otherwise similar to several other Southern classes.

Builder information from B Rumary list supplied by Allen Stanley in March 2004. Works numbers were 2008-2015 (October-November 1899) and 2165-2194 (1900) . They were later renumbered 283-289 and 323-352.

Most were scrapped by the Southern in the 1930s and 1940s. 338 went to the Atlantic & Yadkin in April 1937, keeping the same number.(The A&Y ran from Mount Airy to Sanford in North Carolina from 1900 to 1950.) It was returned to the Southern for scrapping in October 1945. 348 experienced a similar history, going to the A&Y in August 1936.

David Bott, who maintains the definitive A&Y website (http://southern-railway.railfan.net/ay) explains the attraction of this class for the A&Y:"This little consolidation was used on the Climax to Ramseur branch because it had a wheelbase sufficiently short for the turntable and was light enough for the weak trestles on that line."

347 was picked up by the Baltimore Shipbuilding Co in July 1935 as a switcher.

Class H-3 (Locobase 6490)

Data from the Southern Railway locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive collection. See also Prince (1965). Works #2008-2014 in October-November 1899 and 2165-2194 in October- December 1900.

Similar to the Alabama Great Southern D (Locobase 6109), this larger class had slightly larger boilers. They were delivered from Pittsburgh in two batches, a small one of 7 in 1899 and the larger run in 1900. By 1910 (when diagram 22-F-35 was prepared), they'd been renumbered as shown.

The first scrappings began in 1933 (342, 346). While many H-3s were gone by World War II, a few survived into the late 1940s. 348 was sold in July 1935 to the Atlantic & Yadkin Railroad.

Class H-4 (Locobase 5143)

Data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002).

Principal difference from the H-2 (Locobase 5138) was the use of 57" drivers.

The first to be scrapped went in 1933, but most worked through World War II.

Prince (1965)

Class I (Locobase 2653)

Data from Prince (1965) and List and Description of Locomotives - Southern Railway System (1914) provided in April 2004 from Allen Stanley's extensive collection. Pittsburgh built the first 4 in 1907 (works 44462-44465) while Baldwin built the last 4 in 1909 (works 33693-33694, 33728-33729). The Baldwins originally operated on the Georgia Southern & Florida.

These had the tallest drivers of any Consolidations on the Southern system and were unusual in their use of Walschaert radial valve gear.

They were scrapped between 1934-1938.

Class J (Locobase 2654)

Pittsburgh built 20, Richmond 15. Data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002), where the class is described as a "wide-firebox" variety Consolidation. Evaporative heating surface information from locomotive diagram book provided in April 2004 from Allen Stanley's extension collection

The first to be scrapped went in 1933, the last endured until 1950.

Class K - 437 tubes (Locobase 6113)

Data from the SRY List and Description of Locomotives book supplied in March 2004 by Allen Stanley from his extensive collection.

Alco-Pittsburgh works numbers were 28927-28951 in 1904; road numbers 637-661

Alco-Richmond works numbers were 27508, 28422-28446, 27509-27514 in 1903; 29882-29906 in 1904; road numbers ran 605-636, 697-721.

Baldwin works numbers were 23069, 23075, 23110, 23103 (road numbers 601-604); 24238-24239, 24254-24255, 24259-24261, 24278-24281 in May 1904 (road numbers 672-682); 24296, 24302, 24311, 24325, 24329-24330, 24336, 24355, 24363-24364, 24371-24375, 24401-24402, 24419-24420 in June (road numbers in two series: 683-696 and 662-666); 24434-

24435, 24453, 24484 ( (road 667-670) in July; 24530 (road 671) and 24729-24733, 24749, 24760 (road 722-728) in August.

This was the standard 2-8-0 on the Southern Railway System in the first decade of the 20th Century. Like the AGS D9 class, these CNO & TP engines had a very small firebox heating surface, although the grate area is sizable enough. These preceded the K-series engines shown in Locobase 2655, which had 34 fewer tubes and were produced beginning in 1905.

As with all of the other K Consolidations, these ranged widely and retired only gradually. Most were gone by the end of the 1930s, but a few hung on to be scrapped in 1949-1950. 722 was sold to the East Tennessee & Western North Carolina in November 1952 as their 208.

Class K/Ks - 403 tubes (Locobase 2655)

This was one of the two main variants of by far the largest batch of Consolidations to be procured by the Southern (318) itself, the Cincinnati, New Orleans & Texas Pacific (50), Alabama Great Southern (50 K, 1 Ks), New Orleans & North-Eastern (15), and Georgia Southern & Florida (9).

In 1903 the series started with the 437-tube version; that version is outlined in Locobase 6113. In 1906, the K design featured a 3,300-sq ft heating surface in 403 tubes. The orders were filled in large batches from Alco's Richmond plant as well as substantial orders from Baldwin. Richmond's works numbers were 37620-37669 in 1905 (road #722-778) 39283-39317 in 1906.

Baldwin works numbers were 27059, 27082-27083, 27102-27103, 27118-27120 in December 1905 (road numbers 779-786).

Road numbers 822-876 were produced as work numbers 28874, 28883, 28909 in August 1906; 28923, 28938-28939, 28949, 28970, 28987-28988, 28992, 29001-29002, 29010, 29020, 29024-29025, 29071-29072, 29104, 29142-29143, 29149-29151 in September; 29185, 29204, 29228-29229, 29294-29295, 29303, 29329 in October; 29404-29405, 29493-29494, 29546-29548, 29577, 29611 in November; 29633-29634, 29661-29662, 29693, 29697-29699, 29753, 29823 in December.

Some data from Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002). A separate diagram for engines 601-729 has slight differences in number of tubes (407) and in grate area (53 sq ft). Evaporative heating surface information from locomotive diagram book provided in April 2004 from Allen Stanley's extension collection. See also Locobase 6112-6113.

Many of the K-class engines (393 of them) received a refit in which the Universal valve chest with piston valve was bolted right onto the square slide-valve casting, the boilers received superheating, and Stephenson valve gear was replaced (in most cases by Southern valve gear). See separate database entry.

Class Ks - 22 1/2"" cylinders (Locobase 5141)

Southern Railway diagrams hosted on southern.railfan.net/images/archive/southern/steam_loco_diagrams (viewed September 2002), supplemented by SRY 5 - 1943 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Many of the Southern's Ks engines (393 of them) received a refit in which the Universal valve chest with piston valve was bolted right onto the square slide-valve casting, the boilers received superheating, and Stephenson valve gear was replaced (in most cases by Southern valve gear, but some examples had Baker and other Walschaert gear).

The result is shown in the specifications. The superheater area is an estimate, based on several 2-8-0s for which that dimension was already known that shared the same number and diameter of flues and the same flue length.

See also Prince (1965) and Dale Roberts/Bill Schafer in Drury (1993).

Class Ks-1 (Locobase 6114)

Data from the 1917 - 2 Alabama Great Southern locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection. Works number was 33795 in September 1909.

This was a one-off based on the D9 / K class, but with 2" larger cylinders and a superheater as part of the kit. The working pressure shown in the specs is precisely recorded in the 1912 diagram. The total CHS seems high, but internal evidence suggests it's correct. Locobase suspects that the "superheater" actually was a smokebox pre-heater or other such device that infused steam with only a slight boost in temperature.

Delivered in 1909, it was unique and remained so until it was retired in 1947.

Sometime before 1924, cylinder diameter was reduced to 24" while boiler pressure rose to 190 psi. Some of the earlier D9s were rebuilt to the same standard, according to the 1924 Southern chart, which also gives the heating surface as 2,325 sq ft.

Class Ks-3 (Locobase 410)

Served coal mines north of Knoxville, Tenn. Equipped with feedwater heaters and mechanical stokers. Firebox heating surface included 26 sq ft of arch tubes. The piston valves measured 12" in diameter with 7 1/2" travel.

Blessed with lots of available steam, these were the heaviest Consolidations in Southern service and served the coal lines well until the 1950s. Four were sold to the Interstate Railroad (25-28) on 17 July 1952.

Class Ks-4 (Locobase 6097)

Data from the 1927 New Orleans & North Eastern locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive collection. Works numbers were 66913-66917.

Firebox heating surface included 25 sq ft of arch tubes. The superheat surface area is estimated, and is based on the very similar KCS E-3 Pacific of virtually identical dimensions (see Locobase 5093).
