Class 1/D/B/C (Locobase 7708)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.Works numbers were 439-440 in August 1886; 596-597.

Organized on 14 December 1885, the P&P ran west for 31 1/4 miles (50.3 km). The first two small Americans rolling on small drivers made up the entire motive power stud. Within a year, the P&P came under the Kansas City & Pacific and the pair took #51-52, then 301-203 in 1889. Along the way, Dickson delivered four more of the class in 1887, numbering them 53-56 and later 303-306.

More than a decade later, the KC&P merged with the Missouri-Kansas-Texas.

The Katy renumbered them as shown above. In 1912 the same half dozen were renumbered again 323, 325, 326, 324, 327, 328, As the latter, the first four went to the scrapper in May and June 1916 with 327-328 following in December 1921.

Class 101 (Locobase 13325)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 34, p. 60. Works numbers were 35193-35195 in September 1910 and 36169 in February 1911

The Wichita Falls Route included the Wichita Falls & Southern Railway, the Wichita Falls & Northwestern, and the Altus, Wichita Falls & Hollis. The route was not a challenging one, which may explain why these mixed-traffic locomotives were so small. Ruling grade was only 3/4% and curves with gentle 3-degree radii. Rail weight was 60-65 lb/yard (30-32.5 kg/metre).

When the Missouri-Kansas-Texas bought this quartet in 1912 and 1914 (101), it renumbered this quartet 920 to 923. The 922 and 923 were lettered for the Altus, Wichita Falls & Hollis. The railroad was bought in 1923.

Class 195 (Locobase 11645)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Volume 15, p. 215. Works numbers were 10630-10631, 10633-10636, 10640 in February 1890.

Soon after this class was delivered, all of the locomotives had their cylinders bored out by 1/2" and the driver diameter increased to 68".

As modified, five of the six 1890 engines joined four 1892 engines (Locobase 7713) in class E-3 and were renumbered 275-281.

Class 320 (Locobase 8460)

(Note: Official name for the Cotton Belt was St. Louis-Southwestern.)

Data from StL&SW 1 - 1932 Folio 725 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Information on #320's career from Joseph A Strapac, Cotton Belt Locomotives (Huntington, Calif: Shade Tree Books, 1977, reprinted in 1999 by Indiana University Press), p. 27.

This locomotive remained in service for more than 50 years. It was delivered as 191 to the Chicago & Alton in 1880 (Schenectady works number 1232 in March). Twenty years later, it was sold to the Missouri Midland in March 1900 as their #48. The MM was sold to the Katy in March 1901, but the 48 kept its number until 1912, when it was renumbered 320. In 1919, the Katy rebuilt the locomotive to the specifications shown above.

After a sale to locomotive brokers Hyman Michaels in 1924, the latter sold the 320 to the Deering & SouthWestern in that same year as #9. Taken over by the Cotton Belt in 1929, the 9 operated until the summer of 1933 when it was scrapped.

Class A (Locobase 7703)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

Locobase knows only what the diagram tells him and it says that for the period, this was a small Eight-wheeler. Moreover, the Grant & McQueen engines of nearly a decade earlier (Locobase 7704) had the same general dimensions.

---

Class A (Locobase 7705)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange and DeGolyer, Volume 8, p. 45. Works numbers 4164-4165, 4167-4168 in September 1877 and 4176-4177 in October 1877.

Part of a series of MKT Eight-wheelers with the same power dimensions, this was too a relatively small engine. A couple of years later, Baldwin followed with slightly larger locomotives; see Locobase 7706.

Class B (Locobase 7706)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange and DeGolyer, Volumel 8, pp. 137. Works numbers were 4012, 4014 (October 1876), 4017, 4019 (November 1876), 4038-4039 (December 1876), 4154, 4157, 4169-4170 (September 1877).

Baldwin's earlier A3 (Locobase 7705) had power dimensions similar to most other Katy Eight-wheelers of the time. This class had slightly larger cylinders and saw increases in most key measurements. Danforth, Cooke added three in 1882.

Class B (Locobase 14132)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also General Description of Locomotives M.K.&T 1890 supplied by Allen Stanley in April 2012. Works numbers were 490-493 in April 1873, 495-501 in May.

Rogers and Mason Locomotive Works produced this order in the early '70s. Mason's ten had larger grates and fireboxes than the Rogers engines shown in Locobase 7707.

(The MKT's 1903-1904 diagrams showed the tube counts, dimensions, and length used in Locobase's specs, but apparently added the firebox area twice to arrive at 1,069 sq ft/99.31 sq m).

The 52 was later operated by the Sherman, Shreveport & Southern, went back to the MKT, then to the Houston & Brazos Valley.

NB: Locobase estimates the evaporative and direct heating surface area by using the firebox dimensions presented in the MKT description book, calculating an estimated firebox area, and comparing it to the known dimensions of the Rogers-built Bs.

Class B2 (Locobase 7709)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

Although considerably bigger than other MKT Eight-wheelers still on the books in 1904, this class sat in the middle of the rankings for North American 4-4-0s of the period.

---

Class B4 (Locobase 7711)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

This pair was built by the Katy at the same time as the B2s shown in Locobase 7709, but these had taller drivers and hence a longer wheelbase. The Katy produced the 115 in 1890 and the 114 in 1893.

---

Class C/A (Locobase 7704)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

Grant delivered most of the locomotives in 1871-1872; McQueen contributed one in 1876. Although there were other Grant 4-4-0s on the MKT at this time, these fourteen shared tube number and length and the firebox dimensions. This Eight-wheeler design used small drivers, suggesting speed wasn't a leading requirement. The Grants remained in service for 20-30 years

Class C/B/C (Locobase 7707)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange collection. works numbers were 2291-2292, 2294 in June 1873, 2314 in July; 2316, 2323 in August; 2342, 2345, 2350 in September, and 2449 in December 1876.

Rogers and Mason Locomotive Works produced 17 x 24 Eight-wheelers n the early '70s. Locobase 14132 describes Mason's engines. Quite typical of the time, this class had a small grate in what was otherwise a deep firebox with a healthy heating surface area.

(The MKT's 1903-1904 diagrams showed the tube counts, dimensions, and length used in Locobase's specs, but apparently added the firebox area twice to arrive at 1,069 sq ft/99.31 sq m).

The MKT withdrew most of the entire class in the first decade of the 20th century. Road numbers 64-65 remained, but were scrapped in August 1912.

Class C/E-3 (Locobase 7713)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Volume 17, p. 265. Works numbers were 12669-12671 in May 1892 and 12863 and 12872 in August.

The MK&E succeeded the optimistically named Cleveland, Saint Louis & Kansas City, whose charter application was filed in March 1888. (The CSLt&KC was sold by its owner, the Southwestern Company, to the MK&E in March 1892.) The MK&E kept its name for less than two years before being taken into the Missouri Kansas Texas.

This class repeated the 1890 septet of Americans described in Locobase 11645, but increased cylinder by 1/2" (12.7 mm) for a wee bit more tractive effort.

Not long after these engines came on the railroad they and fiveof the 1890 group were given 69" drivers and grouped in class C2. (278 and 281 retained their 63" drivers a while longer while 284 apparently was completed with 63" drivers, but 18 1/2" cylinders).

The entire class went into the shops in 1924-1925 and emerged with superheated boilers; see Locobase 7732

Class C1 (Locobase 14133)

Data from MK&T 1903 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

According an Edson & Weber roster compilation, this locomotive was a rebuilt Baldwin 4-4-0 from 1864. It differed only slightly from several other Katy-built (or rebuilt) Americans.

---

Class C3 (Locobase 7714)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

The Parsons shop built this pair of Eight-wheelers in what seems to have been an effort to upgrade 4-4-0 power.

---

Class E3 (Locobase 7732)

Data from MKT 1904 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

These were rebuilds of 4-4-0s (probably the C2s shown in Locobase 7713) that the Katy had originally procured in the 1890s. One wonders how much of the original engine was left. The grate was smaller, the boiler revamped with superheater flues, piston valves replaced slide valves. On the other hand, the wheelbases remained the same and the boiler's overall dimensions were essentially unchanged.

Trundling along on light branch lines, some of these rebuilds lasted to the end of steam on the MKT.
