Nykarleby 0-4-2 Locomotives in Finland


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 12292)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 20, p. 232. Works number was 16113 in August 1898.

Little wood-burning tank based on Baldwin's "Plantation Specialties". The 12.43-km Nykarlby closed in 1917 and the 1 went on to the MSnttS-Vilppula Railway more than 200 km due north of Helsinki (and later part of the Western SuomenselkS Railway) as their #4. By 1921, it had been sold to the paper mill owned by G A Serlachius Aktiebolag in MSnttS.

(See the Gerlachius Museum's website for an account of Gÿsta Michael Serlachius - [link] -- later owner of GA Serlachius and noted art collector.)


Class 2 (Locobase 12387)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 22, p. 222. Works number was 17346 in January 1900..

Locobase 12276 describes the first saddle-tank to operate on this Finnish railway. When Nykarleby returned to Baldwin for a second of similar layout, however, it bucked the usual trend and ordered a smaller locomotive with a smaller boiler on a shorter wheelbase.
