Gulf, Colorado & Santa Fe / Oklahoma Central / Kansas City, Mexico, & Orient / Denver, Enid & Gulf / Santa Fe 2-6-0 "Mogul" Type Locomotives

Class 0189 (Locobase 8222)

Data from AT&SF 7 -1901 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Information about how many, when, and by whom this class was supplied from http://atsf.railfan.net/atsfstea.html (also visited 6 Feb 2006), the Santa Fe All-Time Steam Roster maintained by Evan Werkema .

Class 146 (2) (Locobase 8908)

Data from AT&SF 9 - 1920 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Information about how many, when, and by whom this class was supplied from http://atsf.railfan.net/atsfstea.html (also visited 6 Feb 2006), the Santa Fe All-Time Steam Roster maintained by Evan Werkema .

Although fitted with only a modestly scaled boiler for a late-1880s Mogul and possessing a light axle loading, this engine did have a relatively large grate.

"THE DENVER, ENID & GULF RAILROAD CO.

GUTHRIE TO KIOWA

117.10 Miles

Incorporated in Oklahoma as the Denver, Enid and Gulf Railroad Company, March 31st, 1902, by the five Frantz Brothers.

Sold May 22nd, 1907 to the Eastern Oklahoma Railway Company. Sold to the Atchison, Topeka and Santa Fe Railway Company, June 20th 1907."

Class 15 / 147 (2) (Locobase 8979)

Data from AT&SF 9 - 1920 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Information about how many, when, and by whom this class was supplied from http://atsf.railfan.net/atsfstea.html (also visited 6 Feb 2006), the Santa Fe All-Time Steam Roster maintained by Evan Werkema . Works number was 27038 in December 1905.

This Mogul was delivered to the D E & G with Alfree-Hubbell valves, a variation of the basic slide valve that is explained in greater detail in Locobase 5344. Its chief value was said to be that the exhaust opening and closure both happened later in the stroke and the exhaust port's size allowed faster clearance of the cylinder.

The DE & G was sold to the Santa Fe in 1907 and 15 joined the 142 class as 147. Locobase does not know if the A-H valve had already been removed. 147 was scrapped in 1927.

Class 2445 (Locobase 804)

2 engines in this class, ex-St Louis-San Francisco (Frisco); see Locobase 4145.

Deep firebox meant that the third driving axle was spaced two feet farther from the second axle than the second was from the first. Note the inside valve motion on this relatively small locomotive. Engine 2446 used 170-lb psi, registered 22,750 lb tractive effort.

(Note: The Santa Fe's official name was the Atchison, Topeka, & Santa Fe or AT&SF.)

Class 2526 (Locobase 805)

9 engines in this class.

Compared to the earlier Mogul #2446 of the AT&SF, this class, built at Alco's Cooke works, had more even driver spacing, much greater power. The BDF and short tube length also shows that this boiler was worked very hard.

One engine -- 2531 -- had 57-in drivers and developed 37,700 lb of tractive effort, reached an almost incredible 1,173 BDF and GDF of 80,490, and attained a 4.81 factor of adhesion.

According to the AT&SF drawing of the class, these were originally numbered by Orient in the 130-155 range.

The Railroad Gazette of 4 January 1907 announced that the KCM & O had ordered 20 Moguls with Allfree-Hubbell valves (see Locobase 7820 for a description of this rarely used design) for delivery in July and September 1907. He suspects that the order was modified to the set of 10 descibed herein in part because of the sharp drop in the US economy prompted by the Panic of 1907, but also because the A-H valve design had proven not to be worth the trouble of installing and maintaining.

Class 501 / 865 (Locobase 8398)

Data from AT&SF 9 -1920 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Information about how many, when, and by whom this class was supplied from http://atsf.railfan.net/atsfstea.html (visited 6 Feb 2006), the Santa Fe All-Time Steam Roster maintained by Evan Werkema. Works numbers were 29347 and 29361 in October 1906 and 29893-29894, 29946 in January 1907.

Locobase 8397 shows the 4-4-0s that helped the OCR open its service in 1907. These Moguls were delivered at around the same time and were considerably bigger and more powerful. Once the OCR was bought up by the Santa Fe in 1917, the new owner took all 5 into its service where they ran for another 10 years. 865 was the first to go, being scrapped in April 1927; the last was 866, which was dismantled in November 1929.

Class 566 (Locobase 8223)

Data from AT&SF 7 -1901 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Information about how many, when, and by whom this class was supplied from http://atsf.railfan.net/atsfstea.html (also visited 6 Feb 2006), the Santa Fe All-Time Steam Roster maintained by Evan Werkema .

The Santa Fe maintained this class as 4-cylinder Vauclain compounds for a bit longer tham most railroads, only simpling them in 1918-1920. Many were later converted to 0-6-0 and 0-8-0 switchers.

Class 591 (Locobase 4889)

Moguls built by Baldwin for the Atchison, Topeka & Santa Fe and described in a 1906 Baldwin catalogue which is reproduced on http://www.railroadextra.com/blatsf.hmtl . Relatively generous grate dimensions meant a low GDF. Many were later converted to 0-6-0 and 0-8-0 switchers.

Class 68 / 0194 (Locobase 8900)

Data from AT&SF 9 -1920 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Information about how many, when, and by whom this class was supplied from http://atsf.railfan.net/atsfstea.html (visited 6 Feb 2006), the Santa Fe All-Time Steam Roster maintained by Evan Werkema.

A relatively numerous class of Moguls, this class was produced in ones and twos in 1886-1888. The Connelly records for this number series show three different driver diameters (48, 54, 57).
