Works numbers were 40672-40673 in September 1913.

The MVRR retained the same power dimensions in this pair of Consolidations that it used in all of the earlier Baldwins (Locobase 11530) and retained the same grate area. But the boiler and firebox grew considerably and steam admission came through Walschaert's outside constant-lead radial valve gear.

Class 201 (Locobase 6782)

Data from 1918 KO & G Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Volume 43, pp. 106+. A summary of the Muskogee Company empire appears in the Muskogee Company records, DeGolyer Library, Southern Methodist University, [], last accessed 26 April 2015. (Thanks to Chris Hohl for his 17 November 2018 email noting the proper sequence of road numbers, the class's original boiler pressure, and changes in valve gear.) Works numbers 33960-33961 in October 1909; 35254-35255, 35294-35295 in September 1910; 36587-36590 in May 1911.

It may split a hair or two to distinguish this group of Consolidations from the 1912 engines described in Locobase 9474, but there were differences in tube count from one to the next. After they began service, Chris Hohl reported, the class raised its boiler pressure, first to 185 psi (12.76 bar) by 1917 and to 200 psi (13.8 bar) by 1923.

Class 201-superheated (Locobase 16379)

Data fromKO&G 8 - 1923 and KOG 1944 Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. (Thanks to Chris Hohl for his 17 November 2018 email noting the proper sequence of road numbers, the class's original boiler pressure, and changes in valve gear.)

Locobase shows the Consolidation locomotives delivered in batches of ten in 1910 (Locobase 6782) and in 1912 (Locobase 9474) with saturated boilers. By 1917, at least ten of the two classes had been fitted with superheaters and Southern valve gear. By 1944, the MO&G's successor Kansas, Oklahoma & Gulf showed twelve locomotives from the two classes, all fitted with Southern valve gear. Six engines- 219, 223-229, 233--one from the 1910 batch and five from the 1912 batch, had superheaters. The other six included three from the 1910 group--205, 207, 217--and three from 1912--221, 235, 239--retained their saturated boilers.

NB: Superheater area is estimated based on similar installations with the same flue count, length, and diameter.

Class 221 (Locobase 9474)

Data from 1918 KO & G Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. A summary of the Muskogee Company empire appears in the Muskogee Company records, DeGolyer Library, Southern Methodist University, [], last accessed 26 April 2015. See also DeGolyer, Volume 43, pp. 110+. Works #37412-37413 in January 1912 and 37582-37585 in May; and 37786-37789 in June.

This class had slight differences in tube count and firebox heating surface from the 1909 design shown in Locobase 6782. Note that neither group was superheated - nor would they be.

In 1929, the 235 was traded to the Osage Railway for that road's 2-10-0 #10.

Class 4 (Locobase 12994)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 29, p. 153. See also "Locomotive Building", Railroad Gazette, Volume XL, No 26 (29 June 1906), p. 187. Works number was 29014 in September 1906.

Locobase 11530 shows the base class of Consolidations from which this locomotive differs in having a wide Wootten firebox. The RG's data doesn't match up with the Baldwin specs in most respects, but does confirm that the engine had the big grate. As specified, the 4 had an 8 ft wide grate (2,438 mm).

The 4's photograph appears in Mike Condren's Muskogee Company website at [], last accessed 26 April 2015. Taken at Baldwin's works, the picture shows the usual cab over the middle drivers, but showed its steam dome perched incongruously on the firebox behind the cab and ahead of the safety valve stand. Only the bell is located forward. .

The Midland Valley was a line that operated northwest-southeast between Wichita, Kans and Fort Smith, Ark, serving Muskogee and Tulsa, Okla along the way.

After several years with the MV, 9-10 were sold to Cherokee Consolidated Company. In the 1907 specs, noted that the 19 was sold in 1909 to the Denver, Laramie & Northwestern and 20-21 to Hodges, Downey & Company for resale.

20-21 soon went to the Crystal City & Uvalde in Texas as their #22 and #21,respectively ; the CC&U soon evolved into the Link Route -- the San Antonio, Uvalde & Gulf . See Locobase 7819 for the superheated makeover the Sausage Line soon applied to both of these engines. Ultimately the two wound up on the Missouri Pacific in their class C-50 as road number 1004 1005.

Class C-50 - 29.4 (Locobase 7819)

Data from MP 8 - 1936 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Soon after they arrived on Texas's MV, this pair was sold to the Hodges Downey Corporation, who sold them to the Crystal City & Uvalde, which was reorganized in 1912 as the San Antonio, Uvalde & Gulf.

The "Link Line" (aka the Sausage) began as the Crystal Lake & Uvalde connecting those two towns southwest of San Antonio. The system grew quickly. The North-South line extended a few miles further south to Carrizo Springs even before the line was begun. Once it was complete, land speculation by "colonizers" encouraged eastward expansion from Crystal Lake on a road that curved north to Pleasanton. By this time, the SAU & G intended to link Pleasanton and Corpus Christi to its southeast; it was logical to connect Pleasanton to San Antonio. The final Sausage layout resembled an upside-down Adirondack chair (or a laid-back, lower-case h). (Use your imagination or look up the map at [].)

Although the original line and its link to Pleasanton soon proved unprofitable, the San Antonio-Corpus Christi link proved valuable to the Missouri Pacific (through its purchase by the New Orleans, Texas & Mexico in 1925).

The MP renumbered the pair once again.

Neither of the available locomotive diagram books includes the actual superheater area; Locobase estimates that it measured approximately 350 sq ft.
