VR 2-8-0 Locomotives in Finland


Class Details by Steve Llanso of Sweat House Media

Class K1/Tk1 - Amerikan satikka (Locobase 5643)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003). Additional information from the animator's railroad website -- [] (2 April 2003) -- gives us Baldwin's works #:

17301-17306 (271-276) and 17312-315 (277-280) in 1899,

17413-422 (281-290) in 1900.

The photo shows a small, low-drivered locomotive with a leading truck that looks almost like an afterthought and a plump balloon stack. The last of these retired in 1959.


Class K2/Tk2 - Satikka (Locobase 5644)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003).

These are suomifications of the Baldwin 2-8-0s that arrived a few years earlier. In the process of taking the lines, the Finnish builder enlarged the cylinder volume and shrank the boiler and grate. (This seems to have a frequent design change during such adaptations.)

Tampella produced the class in batches as follows:

1903 407-415

1904 416-426

1905 457-461

1906 462-470.

The last of these retired in 1960.


Class K3/Tv1/Jumbo (Locobase 4223)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003). Wheelbases and weights from http://www.the-blueprints.com/blueprints/trains/trains-e-g/32924/view/finnish_steam_locomotive_tv1/

Karvonen's entry lays out the constructors as follow:

918-920 1936

Hannoveresche Maschinenbau

712-721 1923

Nyqyvist & Holm

900-909 1928


Class K4/Tv2/Wilson, Kaalimato (Locobase 4224)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003). Wheelbase and weights from http://www.the-blueprints.com/blueprints/trains/trains-e-g/32925/view/finnish_steam_locomotive_tv2/ . See also Roy V Wright (Ed.) 1922 Locomotive Cyclopedia of American Practice, Sixth Edition (New York: Simmons-Boardman Publishing Company, 1922), p. 1006.


Class K5/Tk3 Pikku Jumbo (Locobase 4222)

Data from Markku Karvonen's Finnish website personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003). Wheelbases from http://www.the-blueprints.com/blueprints/trains/trains-e-g/32923/view/finnish_steam_locomotive_tk3/

The information reveals that this class was built in small bunches over many years. The first 100 were delivered quickly from 1927 to 1930 by Tampella and Lokomo. Lokomo added 8 more in 1943, but the bulk of the remainder (including a batch (1147-1166, 1949) from Frichs in Denmark) were delivered by Tampella and Lokomo in the late 1940s. The last 4 came in 1952-1953.

Ziel and Eagleson (1973) photos show a compact, low-drivered wood-burner with cabbage stack.

[] (26 April 2003) translates the designator as follows:

Tyyppi/Type:Tk3 Numero/Number: 1168

T= Tavarajunaveturi / Freight locomotive

k= kevyt (akselipaino alle 11 tonnia) /light-weight class, (axle weight under 11 tons)

3= jSrjestysnumero / serial number


Class M1 (Locobase 5618)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003).

Karvonen gives the tractive effort as 9,855 lb, which uses the continental 0.65 conversion factor instead of the 0.85 applied by British and American designers. But even when using 0.85, 12,888 lb is the result, not what's shown above. Locobase cannot read Finnish well enough to determine why there is a big discrepancy.
