Minarets & Western / Sugar Pine Lumber Co 2-8-2 "Mikado" Locomotives in the USA

The Minarets & Western Railway was a subsidiary of the Sugar Pine Lumber Co that was built to link their logging operations near the Minarets to the sawmill at Pinedale Ca. From Central Camp, the Sugar Pine Lumber Co railroad ran 11 miles to the switch yard at Wishon where the Minarets & Western ran 53 miles to the mill as a mainline operation. The southern portion of the line was operated with joint trackage rights with Southern Pacific.

The companies were established in 1921 but never made a profit before bankruptcy ended operations in 1933. In 1935 the SP purchased the Pinedale section and the four Mikado locomotives of the Minarets & Western Railway Company (#101- #104). They had cab side numbers and tenders we marked with "Minarets & Western Ry Co".

#101. The #101 was Alco 61858 originally ordered by the Oregon-American Lumber Company in 1920, but the order was cancelled and the locomotive was purchased by the Sugar Pine Lumber Co in 1921.

After its absorption by the Southern Pacific, the 101 retained its number. Later, it was sold to locomotive rebuilder/reseller Birmingham Rail & Locomotive which sold it to the Aberdeen & Rockfish in 1935 as their #40. It eventually wound up on the Valley Railroad.

#102-#104. The #102-#104 were heavier locomotives built by ALCo in 1923. I cannot find details of these locomotives other than construction numbers 64144-146. In 1935 they were sold to the Southern Pacific.

The #102 and #104 were given road numbers 3295 and 3296. They worked as switchers in the SP Dunsmuir yards. The #3295 served there until 1953. In 1940 #3296 (ex M&W #104) was sold by SP to the Long-Bell Lumber Co. at Tennant, Ca. She carried her former SP number of #3296 with Long-Bell and served there well until the end of the Tennant operations.

The #103 was sold to Southern Pacific but not used, sold to Atlanta & St Andrews Bay #300, in 1938 sold to Chicago & Illinois Midland #527, scrapped in 1954 (foothills Rails info) In August 1951 it was retired and scrapped (Don Ross Group).


Class Details by Steve Llanso of Sweat House Media

Class 101 (Locobase 14276)

Data from http://www.trainboard.com/grapevine/group.php?discussionid=884&do=discuss. See also Edward J. Kamholz, Jim Blain, Gregory Kamholz, The Oregon-American Lumber Company: Ain't No More, (Stanford University Press, 2003), p. 53. Works number was 61858 in 1920.

When the Oregon-American Lumber Company discovered how ill-suited this relatively large Alco was for forest work, it refused delivery of the engine and sent it off to the M&W.

After its absorption by the Southern Pacific, the 101 retained its number. Later, it was sold to locomotive rebuilder/reseller Birmingham Rail & Locomotive which sold it to the Aberdeen & Rockfish in 1935 as their #40. It eventually wound up on the Valley Railroad.


Class E-4 / Mk-10 (Locobase 8727)

Data from SP Menke All Time Steam Locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also http://basslakeca.com/history.html, accessed 9 September 2007.

One could have figured these Mikados were intended for a logging road - their low drivers and short wheelbase suggest as much. The San Joaquin Valley's river system promised to support a lot of hydro-electric power and the San Joaquin Electric Company was formed in 1902 in northern California. They created the Crane Valley Reservoir, which was later renamed Bass Lake when it was restocked after all of the existing fish died from SJEC actions.

In the 1920s, the M&W was created by the Sugar Pine Lumber Company. A common carrier, the M& served a 53-mile right-of-way from the Fresno vicinity to Wishon, CA, which lay at the western end of Bass Lake. Its primary role was to bring logs to a big sawmill at Pinedale, but that venture failed after eight years.


Class unknown (Locobase 1312)

Data from Bruce (1952). Note that former Coos Bay Lumber Company 2-8-2STs 10 and 11 (Alco works # 68548 in December 1930 and 68276 from December 1929, respectively, seem to be the same design.)

Last of three Mikado tanks for this lumber company and more powerful than the other two. Sugar Pine's bankruptcy in the early 1930s led to the sale of #4 to Pacific Lumber Company and operated as #37 from 1935-1962.

Purchased for tourist railroad WaWa & Concordville where it operated briefly in the late 1960s, bought in 1980 by the Wilmington & Western in Marshallton , DE. Stored there until repairs (1983-1987) made it possible to re-enter service in 1987. In 1990 a dispute over who was to pay for needed repairs idled the locomotive.

In May 2003, the Timber Heritage Museum of Eureka, Calif contracted to buy the 37. In Spring 2006, the locomotive was delivered to the Strasburg Railroad in Pennsylvania to begin a leisurely restoration.
