Chartered as the C-SPR in 1910, the railroad actually entered service under Santa Fe ownership as the South Plains & Santa Fe in 1916. The SP & SF was leased to the Panhandle & Santa Fe in 1917, a relationship that lasted until a merger in 1948. The first 64-mile segment from Lubbock to Seagrave opened on 1 July 1918. At that time , the SP & SF reported owning 2 locomotives, one of which was the mixed-traffic Ten-wheeler shown in the data.
The 0226 was scrapped in September 1929.
This was a single Ten-wheeler locomotive (works #13748) brought into the Santa Fe from the CE. It was identical to the larger 283 class except for a set of smaller drivers.
2238 in February 1893, 2321-2323 in June, 2476-2477 in October 1894, and 2521-2522 in February 1895
Shown in the 1920 book as SFP & P engines and numbered 1-9, this class came with two wheelbases and originally went to two railroads. The first 5 had a longer driven wheelbase of 14 ft and an engine wheelbase measuring 23 ft 10 in. 6-12 had the shorter wheelbase shown in the specs.
According to Werkema's roster, the first 9 went to the SFP & P in 1893-1895, the last 3 to the Prescott & Eastern (a non-operating subsidiary) in 1898; see Locobase 2980.
The railway itself is the subject of a 24 January 1999 article by Eleanor Gilley preserved on the Sharlot Hall Museum website -- http://www.sharlot.org/archives/history/dayspast/text/1999_01_24.shtml, accessed 6 May 2007. (The museum's focus is Yavapai County.)
Gilley's article on the "Peavine" begins:
"As the railroad left Prescott on the west side, it began its slow ascent for nine miles to the summit of the Sierra Prieta Mountains at Prieta, elevation 6,108 feet. The view from the top was breathtakingly beautiful with the black range of mountains, the Mogollan Rim and the surrounding scenery. The line then descended for 14 miles past Iron Springs and Ramsgate Hill around twisting, winding 12 degree curves and challenging three percent grades to Skull Valley, elevation 4,240 feet.
...It was called an engineering masterpiece. There were many fills, deep cuts and long timber trestles. Near Devil's Gate, a cut of 57 feet was required through solid rock. A 25 foot deep hole was drilled and loaded with powder to produce the largest discharge ever executed by a single shot in this territory. Fortunately, the workers had been asked to leave camp because one large rock went through a tent with such force that if it had not bounced, it would have buried itself."
Gilley later tells us that the nickname came from a comment about the route, which twisted like a peavine.Intended to link Northern Arizona towns like Prescott with the Atlantic & Pacific mainline of the Santa Fe, the Prescott & Central Arizona was a combination of two rival groups of investors that opened its Prescott-Seligman leg at 31 December 1886.
But the railway was not successful and needed further infusions. The result was the SF P & P, which was incorporated in 1891. The "Scenic Railway of Arizona" dropped south from the A & P's Ash Fork junction through Chino Valley and Granite Dells to Prescott. That section opened on 24 April 1893 with the segment south of Prescott opening on 4 March 1895. The SFP & P, which had taken operating control of the Arizona & California in 1905, itself was merged into the Santa Fe's non-operating subsidiary California, Arizona & Santa Fe.
The engine was a transitional type retaining older features such as a full cow catcher, spark-arresting stack that resembled an Olympic torch, and steam dome just ahead of the cab. The cab was steel with a high roof and transom window in front.
This trio of small Ten-wheelers (works #2515-2517) formed part of the GB & KC roster when that railroad was taken over by the Santa Fe. 143 had 20 fewer tubes by 1920 and a total heating surface of 1,396 sq ft.
Produced by the same builder that supplied the 12 in the mid-1890s (Locobase 8395), this trio was 10 years newer. Although the grate remained the same size and the boiler tubes were no longer, cylinder volume grew as did the number of tubes in the barrel. Also, boiler pressure increased and weight grew as well.
The 1920 diagram showed the class's provenance as the S F P & P, but Werkema's roster traces them back to the Arizona & California. The last was retired in 1929.
The 1920 diagram book gives 16.8 sq for the grate area, but measures the firebox length and width as 96" x 33". That figure yields a more likely proportion between firebox and boiler, and that is the number used.
Oddly, this class of Rhodies had only a short career on the Santa Fe, leaving service by 1903.
This is part of a very large class of Ten-wheelers supplied by a single builder in just two years. This smaller group had the shorter tubes, which cut heating surface area by 68 sq ft. The other 55 are profiled on Locobase 8232.
The last in either class left service in 1937.
As noted in Locobase 8231, Brooks supplied this large class of Ten-wheelers in just two years. Most of the 4-6-0s had the longer boiler shown in this entry's specs. This meant a longer wheelbase as well.
The last in either class left service in 1937.
See Eleanor Gilley's article "The First Railroad and the 'Battle for Prescott'", Sharlot Hall Museum Days Past, 24 January 1999 and 31 January 1999. (http://www.sharlot.org/archives/history/dayspast/days_show.pl?name=1999_01_31&h=|Santa%20Fe%20Prescott%20%26%20Phoenix|)
The A & P bought these 5 Ten-wheelers from Baldwin in two batches. Works 2177-2178 were produced in June 1870 with 2302-2304 built the following December. Each of the latter had a name: Uriel Crocker (31), Andrew V. Stout (32), and Isaac Rich (33).
For whatever reason, the A & P disposed of all 5 in 1876 by selling them to the St Louis-San Francisco. The Frisco kept them for several decades.
The high numbers of this large class puzzle Locobase, but since the Santa Fe renumbered its locomotives twice in 2 years, he isn't surprised. A big difference from the 18 locomotives delivered by Baldwin a year or two earlier was a reduction in the diameter of the boiler tubes from 2 1/4" to 2". Locobase can't figure why that change was made, but notes that the heating surface area decreased by almost 200 sq ft. The grate also shrank.
The last of these Ten-wheelers was withdrawn in 1929.
Although numbered higher than the 2160s shown in Locobase 8235, these actually preceded that large set of Baldwins. This group was delivered with 2 1/4" fire tubes and a relatively large grate. Werkema does not show this class at all, but the Santa Fe 1901 diagram and the 1902 description of locomotives gives a full look. Locobase can't tell if these were brought in with an acquired railroad and doesn't know how long they served the Santa Fe.
Seven years after the CS took delivery of 7 Ten-wheelers from Baldwin (Locobase 8988), it returned to that builder for four more. Other than a 20% increase in boiler pressure and a 1"-greater piston diameter, the design remained essentially the same. Once the Southern California took over, the numbers were changed, and the Santa Fe changed them again in 1904. The last of the class was retired in 1935.
One of the largest single classes of Ten-wheelers on the Santa Fe, this group was quite typical of an early '90s 4-6-0 design. The diagram gives the boiler pressure as 180 psi, which seems high and may reflect a redesign later in the decade.
The last of this mixed-traffic class retired in 1934.
Like most of the Santa Fe's 4-6-0s, this class enjoyed a long career with the last engine retiring in 1938.
Very like the shorter Brooks engines of 1891 (Locobase 8231), this quintet of Baldwins came to the Santa Fe 3 years later. For some reason, they lasted only a few years on the Santa Fe, being shown as retired by 1902.
This locomotive originally went into service in 1894. It was delivered by Richmond as a cross-compound with one 20" HP and one 32" LP cylinder. Werkema's roster says the Ten-wheeler was simpled in 1911, but the Santa Fe diagram clearly states that it was rebuilt in 1900. It was scrapped in 1924.
Boiler pressure is based on a comment in the next paragraph that BP gradually increased from "130 and 140 pounds [sic]". The higher of the two is taken because it produces a more likely factor of adhesion.
Locobase finds a pair numbered 281-282 in the AT&SF 7 - 1902 Description of Locomotives, but with a redesigned boiler. It was shorter (12 ft 3 in), held fewer tubes (172), and consequently had less tube heating surface. The cylinders measured 17 1/2" x 24".
One of the larger single classes of Ten-wheelers to go to work for the Santa Fe.
The Santa Fe stud of Ten-wheelers grew and grew and this class was among the early designs. Baldwin delivered 4 (works 7873-7875, 7883) in April and 2 (works 8246, 8247) in November of 1886. These had 60" drivers that were later replaced by the 58" wheels on which the rest of the class rode. The 4-6-0s had nearly 40-year careers before being scrapped in the 1920s.
This small set of Schenectadies was delivered over a two-year period. They operated on the Santa Fe for almost 30 years, the last retiring in 1925.
One of the larger orders for Ten-wheelers on the SFP was this large tender to Pittsburgh. The first 10 had 230 tubes, the rest 228 as shown in the specs. These were the most seriously single-purposed 4-6-0s, their small-diameter drivers connoting their drag-freight role. The last of the class was withdrawn in 1932.
In the same year that Brooks delivered its batch of locomotives, Schenectady contributed this sextet. Although offering about the same amount of firebox heating surface, this design had fewer boiler tubes of shorter length. Some rode on 69" drivers and registered a lower tractive effort as a result.
The last of the class was retired in 1927.
These passenger Ten-wheelers showed some growth over the earlier classes of Santa Fe 4-6-0s. The last was retired in 1925.
These followed up the Klondikes of 1897, which are described in Locobase 8242. For some reason, the 1899 batch (works #1032-1041) had 10 fewer tubes of shorter length. Even so, the class proved a good size with some operating for almost 40 years.
1897 was the year of the Alaskan Gold Rush (the one immortalized in Charlie Chaplin's great feature film) and its promise, however illusory, attracted worldwide attention. Klondike (or Klondyke) was a nickname applied to many items, including at least three locomotive classes. One was Henry Ivatt's 4-4-2 Klondyke class, the other was this octet of Ten-wheelers. (A third was the Canadian Southern F-82; see Locobase 3480)
They showed good size and power for their passenger service and the last wasn't retired until 1938.
Note that these express passenger engines were Player tandem compounds designed by Santa Fe's Superintendent of Motive Power. As with most tandem layouts, the lead cylinder was the high-pressure vessel and the rear assembly held the low-pressure cylinder; the two shared a single piston rod. Unlike the Baldwin tandem layout, John Player's layout had the two cylinders separated slightly.
Like most US-operated non-articulated compounds, these ran only a short time as such engines. By 1905, they had been rebuilt with two 19 1/2" x 28" cylinders.
These were right-in-the-middle examples of the American Ten-wheeler as delivered at the turn into the 20th Century.
In 1899, Dickson Manufacturing Company of Scranton, Pa supplied 10 Atlantics (4-4-2) to the Santa Fe (works #1057-1066). They were obviously not regarded as success in that wheel arrangement, possibly because not enough advantage was taken of the smaller trailing wheel to install a larger firebos. In 1904 the Topeka shops modified all of them to a Ten-wheeler arrangement. In the process, they gained 10 speedy 4-6-0s with taller drivers than before spread over a longer wheelbase.
The last of these operated until 1933.
What difference a decade made in the equipment Rhode Island supplied to the Santa Fe. Locobase 8225 shows a freight engine with modest proportions. This entry shows a mixed-traffic machine in sufficient numbers to represent a standard design. The boiler pressure and cylinder volume have both grown considerably. The grate, however, while it now sloped, still sat inside the drivers and could grow only in length (it was now 9 ft long).
Whatever their limitations, these Ten-wheelers endured with 472 going out of service in 1939 as the Santa Fe's last active 4-6-0.
Locobase 4150 shows the first stage in this design's lifetime as it hit the rails in 1901 as a balanced compound with a saturated boiler and the underperforming Vanderbilt firebox. In 1911, the compounding arrangement was replaced by 2 simple-expansion cylinders supplied by Walschaert radial valve gear. At a later date, the shops remade the locomotives by installing a very useful amount of superheating. The last of these was withdrawn in 1938.
14899-14901
This threesome of Ten-wheelers came to the CS in the mid-80s. Although this Barstow-to-San Diego subsidiary of the Santa Fe remained aloof from the mid-1880s consolidation of lines into the California Central, that railroad, the Redondo Beach, and the CS were united in November 1889 as the Southern California. At this time, the 5-7 became the 51-53. 17 years later, the Santa Fe bought the SC outright, two years after the Santa Fe began buying the engines in June 1904.
Over time, the Barstow line has served the Santa Fe as its last leg into the California coast.
This class was very similar to the Baldwin engines that were supplied a year earlier, but had larger boilers and smaller fireboxes. The last 10 of the 317 class had 2 more 2" tubes of very slightly shorter length for the same tube heating surface area (it says here ...); for an alternate view, see Locobase 8238
Two other Santa Fe classes (Locobase 8239 and 8243) had similar grate areas and cylinder volumes, but both of them rolled on passenger-size drivers. The 592 differed also in having the larger 2 1/4" tubes.
As noted in Locobase 8237, which covers the first 20 locomotives in this class of Manchester Ten-wheelers, the last 10 engines delivered to the Santa Fe had two more boiler tubes, but no increase in tube heating surface area. This class was very similar to the Baldwin engines that were supplied a year earlier, but had larger boilers and smaller fireboxes.
The H & S took delivery of a pair locomotives from Manchester (works #1687-1688); a year later the Santa Fe took over the H & S. The firebox heating surface was adequate, but the design's grate area seems meager.
By 1920, the two were substantially different in size and the 390's larger dimensions are shown in 8986. Both were scrapped in 1922.
By 1920, the two Hutchinson & Southern locomotives described in Locobase 8985 were property of the Santa Fe and has different dimensions that included taller drivers. If the grate seemed small in the original design, increasing the number of boiler tubes only increased the disparity. Both were scrapped in 1922
Like many of the Baldwin engines built for the Santa Fe in this era, the 833 was a stocky locomotive with an oddly coned boiler ahead of the steam dome. It had a cast steel frame.
