This must have been one of the last purchases of the short-lived and financially troubled C P & SW. Its Pekin-Streator (Illinois) stretch only opened in 1873 and the line entered foreclosure in 1879. It was reconstituted as the Chicago & St Louis and persisted in laying track toward Chicago (23rd-St station), which was completed in December 1885. The C & St L was purchased by the Santa Fe in March 1902.
In the early '90s, the Santa Fe began rebuilding some of its earlier locomotives with new boilers of higher pressure. Werkema's roster shows that this six-engine class had two principal origins:
1900 number Builder Year original name Year rebuilt Retired
0113 Taunton 1870 E Raymond 1891 1915
0115 Taunton 1871 I T Burr 1892 1922
0112 Taunton 1872 W T Glidden 1892 1915
0114 Taunton 1872 Grasshopper 1892 1922
0111 Baldwin 1882 none given 1892 1923
0116 Baldwin 1882 none given 1892 1916
Two others were rebuilt from similar-vintage Eight-wheelers
0166 Baldwin 1872 Kansas City 1892 1921
0167 Hinkley 1880 George O Manchester 1892 1921
Apparently pleased with the proportions of the rebuilt Eight-wheelers of a few years before (Locobase 8103), the Santa Fe went to Baldwin (works #13921-13928) more in this class of engines . The 1901 diagram shows 73" drivers, but the 1902 locomotive description indicates 63", as does a Peoria & Pekin Union diagram from a few years later when 890 when to work for that railroad in April 1915.
This was a typical, narrow-firebox design of the mid-1875s
The 1901 diagram shows this single locomotive as virtually identical to the earlier 0127s (Locobase 8205), except for a larger firebox and grate plus shorter, but more numerous fire tubes.
Showing the same power dimensions as the Baldwin from the same year (Locobase 8208) and several others, this pair had relatively large fireboxes. They gave about 20 years of service before being retired in 1907.
Otherwise similar in all respects to the typical Santa Fe Eight-wheelers of the time, this quartet boasted 160-psi boilers by 1901. Locobase notes a "revised 1-7-1901" date on the diagram and suspects that the higher PSI dates from that revision. The engines probably entered service with boilers pressed at 140 psi.
Like many Santa Fe engines, these engines were given names as they entered service. Respectively, they were General Burnside and Henry C Cobb. 0153 left in 1907, 0154 retired in 1913.
(Two more Rhodies from that same years -- N K Fairbanks, and Levi L Leiter -- became 0155-0156. In 1901, their diagrams had less information, but was available showed fewer tubes (173) of slightly greater length (11.37 ft) for a tube heating surface area of 1,029 sq ft. Locobase suspects that all 4 engines were delivered to these specs and that 0153-0154 were the only two upgraded to the boiler shown in the main specfications.)
The first of these locomotives bore the name of "Little Buttercup" in the 1880s and arrived as a Hinkley-built engine in 1880. The Santa Fe's shops rebuilt several locomotives to this long-stroke design in 1885-1886.
The OCR was built in 1905-1906 to move coal on a 127-mile main line from mines near Lehigh to the Santa Fe connection at Purcell. It was never really viable because the Santa Fe soon switched its fuel source from coal to fuel oil and a 1911coal-miners' strike led to the closure of the Lehigh mines. The Santa Fe bought the OCR in 1917 "...for 25 cents on each $1000 bond note" according to Wikipedia and merged the defunct line into the main company in 1918.
These small Eight-wheelers must have been among the first motive power purchased by the railway. By 1917, one was no longer on the roster and by 1920, only 0267 still held a space in the diagram book.
The OKC took delivery of these small Eight-wheelers one at a time (works# 29355, 29739, 29759)
This pair showed a relatively large amount of firebox heating surface in relation to its overall heating surface area. Like all of the Eight-wheelers of the time, however, the design used a narrow grate. 062 was retired in 1907 and 063 followed in 1912.
Although the Hinkleys described in Locobase 8210 had relatively large fireboxes, this large class from New Hampshire took the palm for 1881. Since the grate area remained at 16 feet, hemmed in as it was by its placement inside the frame, the extra direct heating surface came from a much deeper installation as well as, Locobase suspects, some arch tubes.
The diagram isn't clear about this small Eight-wheeler, but Locobase suspects that at least two or three engines constituted this class on the SKRR. By 1901, however, only 096 showed on the diagram.
This big class of Eight-wheelers formed the core of the GC & SF as it began service in Texas. For their time (the mid-to-late-'80s), they had relatively big boilers and fireboxes as well as disposing a high adhesion weight. Manchester supplied a very similar 25-engine class to the Santa Fe in the same year (Locobase 7422) that had taller drivers and slightly less heating surface area.
These California-based Eight-wheelers were relatively small for the time, but obviously suited the Santa Fe subsidiary just fine. They remained in service until 1931.
As with Locobase 8894, the compiler isn't able to pin down the exact identity of this locomotive, although he believes it is as represented.
An interesting variation on the big class of express engines shown in Locobase 8216. In addition to reducing the driver diameter to freight dimensions, the builder increased cylinder volume. The result was a more powerful, if quite light, locomotive that served the railroad until 1914.
Even as late as 1920, the diagram shows a classic 1880s Eight-wheeler. In addition to the obvious elements that included a "cowcatcher" pilot, modified, golf-tee style, spark-arresting stack, two domes with one over the crown sheet, the engines also had the equalizing beam visible between the drivers just below the firebox.
The last was retired in 1925.
Around the same time the AT&SF took delivery of a freight variant of the large 23 class (Locobase 8216) with 18" x 26" cylinders, it accepted these 6 passenger engines also fitted with the larger cylinders. In addition, the engines had larger grates.
The last was retired in 1925.

Works #3070-3071 (14, 17) in October 1898
3099-3091 (15-16) in December 1898
3296-3297 (18-19) in August 1899
Locobase is uncertain which of the PV & N locomotives belong here and which were built as shown in Locobase 2152.
Later (1907) Eastern Railway of New Mexico, then Santa Fe (1912). All twelve PV&N/ERNM locomotives were grouped as 238-249 when the Santa Fe took them over.
Narrow firebox measured 8 ft x 33".
These two Eight-wheelers went into service on the 142-mile line between Hutchison, Kansas and Cross, in the Oklahoma Territory. The H & S came under Santa Fe control in 1899.
The biggest single purchase of Eight-wheelers for the Santa Fe, these followed the typical 4-4-0 design that included a deep, narrow firebox. The first 14 (and 51) had an 18-sq-ft grate area. The 69" drivers show these were the standard passenger power for the line in the late 1880s.
Satisfying many requirements and numbering in the dozens, the class served the Santa Fe for over 40 years with the last retiring in 1929.
Mature American type built at Alco's Cooke shops, but with Walschaerts valve gear rather than the more typical Stephenson link motion. Both had one thermic syphon. 2553 operated at 200 lb psi. and had 18-in diameter pistons.
According to Evan Werkema's Santa Fe All-Time Steam Roster -- http://atsf.railfan.net/atsfstea.html, visited 6 Feb 2006 -- these were ex-Kansas City, Mexico, & Orient locomotives 501 & 503 that were never actually renumbered. The later of the two in service was retired by 1930.

Works #2991-92 (7-8) in July 1898,
3014-15 (9-10) in August 1898,
3053-54 (11-12) in October 1898
This engine was slightly larger than the higher-numbered 15 on the PV&NE. Locobase believes the break in the numbers (13 is missing) may represent the point at which the design was slightly modified.
All twelve PV&N/ERNM locomotives were grouped as 238-249 when the Santa Fe took them over.
http://atsf.railfan.net/atsfstea.html (visited 11 April 2003) lists 13 engines in this class (delivered 1875-1879) as of 1900. Connelly's Baldwin list gives only the following works numbers (4575, 4578, 4595, 4597, 4604, 4611-4613).
Werkema shows this single engine to have originally been operated by the Reasor Balanced Valve Company. In other words, this was a demonstrator engine that later entered regular service as a single member of its class. Locobase isn't able to say if the Reasor valves still shuttled in the valve chest. It was retired in 1907.
Locobase isn't able to pin down the exact identity of this locomotive, although it seems likely to have been as shown in the specs.
The first engine later went to the Northwestern Pacific. Succeeding engines entered service with names as follows: San Juan (1875), A G Greely (1878), and F A Manzanares (1878). The latter two went out of service first in 1907, while 08 lasted until 1914.
This Eight-wheeler design had a relatively large grate and firebox area for the time. In fact, although Manchester shipped a slightly bigger engine to the Gulf Coast & Santa Fe (Locobase 8193) in the same year, this class beat the GC & SFs in firebox heating surface (just barely) because of a larger grate.
A mainline passenger engine at first, the type later moved into local service. #95 was the last Eight-wheeler to be retired by the Santa Fe when it was withdrawn in 1940.
For a run-of-the-mill, late-1870s Eight-wheeler, this pair had relatively large grates.
Werkema's roster shows that of the group shown in the Santa Fe diagram (037-046), 3 arrived in 1878, 7 in 1879. Two of the 1878 brood had names, 42 being called M A Otero and 46 named L G Pratt.
Even for its time, this was a small locomotive. Its grate and heating surface areas as well as the adhesion weight number it among the smallest Eight-wheelers operated by a standard-gauge railroad.
According to an article in the Kansas Historical Quarterly by Joseph W. Snell and Don W. Wilson Summer, 1968 (Vol. 34, No. 2), pages 113 to 142.(Transcribed by Barbara J. Scott; digitized with permission of the Kansas State Historical Society.) and reproduced on http://www.kancoll.org/khq/1968/68_2_snell+wilson.htm, accessed 21 February 2007, the usual story of this locomotive's acquisition is slightly askew:
"The locomotive was actually purchased by Charles W. Pierce, treasurer of the railroad, from the Rhode Island Locomotive Works in Providence, about the middle of June, 1869. It was named Gen. Burnside after the Civil War general, Ambrose E. Burnside, who was governor of Rhode Island, an officer of the locomotive works which manufactured it, and a stockholder in the Santa Fe as well as in the construction company building the road. The engine, also a 4-4-0, cost $11,500.—Letter from Pierce to T. J. Peter, June 20, 1869, in "Treasurer's Letter Books," Santa Fe archives."

This locomotive is credited to the "AT&SF"and that points to this being the second locomotive built in the railroad's Topeka shops. Evan Werkema's roster information is uncertain (not his fault, the data look highly confusing), but a footnote in a long presentation by Snell & Wilson in the Kansas Historical Society's Autumn, 1968 -- (Vol. 34, No. 3), pages 325 to 356 -- account of the birth of the Santa Fe (found on ttp://www.kancoll.org/khq/1968/68_3_snell+wilson.htm, accessed 21 February 2007) points to this being the proper identification.
