Peninsular 2-8-2 "Mikado" Locomotives in the USA

ALCO built this 2-8-2T "Minaret" style locomotive new as Crossett Western Co.'s #10 at Wauna, OR in March 1929. The locomotive was sold in 1943 to Hammond Lumber Co. in Samoa, CA and became their #16. It was sold again in 1956 to Georgia Pacific and sold to Pete Replinger in Shelton at an unknown date. It is now lettered for the Peninsular Railway Company and is occasionally steamed up for local celebrations. Number 16 has another operating stable mate from its Hammond Lumber days, the #17 at the Mt. Rainier Scenic Railroad.

Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 14246)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 51, p. 298. Works number was 42639 in November 1915.

Just has they had in 1910, Simpson Logging ordered two Mikados from Eddystone in the small and large categories of logging engines. This one had the same short boiler as the earlier 9 (Locobase 13682), but was half again as big in capacity and weight and saw a useful increase in tractive effort when the boiler pressure was raised 20 psi.

It served the Peninsular until it was scrapped in 1950.


Class Benjamin Snider (Locobase 13682)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 35, p. 285. Works number was 35079 in August 1910.

This was the smaller of the two Mikados ordered by this Simpson Logging-owned railway. Gene Connelly records that the 8 was named Benjamin Snider


Class E Frank Brown (Locobase 13683)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 35, p.p. 283. Works number was 35036 in August 1910.

Peninsular's other Mikado in 1910 (see Locobase 13682 for the smaller of the two) was ordered at about the same time. This engine was a typical Baldwin logging Mike and shared most of its dimensions, areas, and weights with several others. Like the other Peninsular locomotives, the E Frank Brown served the Peninsular and its owner Simpson Logging for decades before being scapped in 1956.


Class Frank Wandell (Locobase 14247)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 53, p.p. 417+. Works number was 44224 in October 1916.

Unlike the #5, which was bigger and more powerful than its short-boilered stablemate (see Locobase 14246), the Frank Wandell had its tubes shortened by 18"(457 mm) compared to the Benjamin Snider (Locobase 13683). Otherwise it was essentially unchanged from the 1910 engine. In fact, the two locomotives were shown in their respective specifications as having the same adhesive and total engine weight, which doesn't seem likely. And compared to the #5, the #11 was estimated to be able to haul 20% more load.

The 11 served Simpson Logging for more than 40 years before being scrapped in 1956.


Class William E Parker (Locobase 15237)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 71, p. 389+. Works number was 56634 in June 1923.

Baldwin's spec page for this oil-burning Mikado saddle-tank logger was headed for the 30 mile (50 km) railway operated by the Simpson Logging Company. The specs show a "well ballasted" railroad with 60 lb/yard (30 kg/metre) rail, curves no tighter than 25 degrees and grades of 4-5% with possible 6% grades if the road were to be extended. Water supply was placed at the 7, 16, 22, and 30 mile posts.

suffered from "defects", which were noted in letters written by two different Simpson Logging Company officials. AW Kelly's letter was dispatched first on 2 February 1924 with AJ Bester's letter following on 8 May. The specs do not give details on the defects.

A later comment entered 9 February 1925 suggested raising a question "regarding redesigning the valve motion bearer crosstie and brake to permit removal of reverse shaft without taking down driver brake cylinder."

Whatever the initial difficulties, the 12 served the PRR for more than 30 years before its scrapping in 1956.


Class William Shorter (Locobase 15494)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 80, pp. 516+. Works number was 60838 in May 1929.

The scale of logging trains operating on the PRwy is suggested by the line's persistent purchase of low-drivered Mikados. This latest one, however, was the first with a superheated boiler. It's possible that the adoption of the hotter, drier steam (which passed through 12"/305 mm piston valves) was seen as an opportunity to reduce the boiler pressure, although most railroads had by 1929 abandoned the tradeoff of boiler pressure and superheat in favor of still more power.

In 1936, the 3 went to work for the Simpson Logging Company. Its fate is uncertain. It may have been scrapped in 1956 or sold to Comox Lumber in Canada as their #16.
