Hango Hyvinge / Suomen valtionrautatiet 4-4-0 Locomotives in Finland


Class Details by Steve Llanso of Sweat House Media

Class A1 (Locobase 5600)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003). Unfortunately, for a number of the early Finnish locomotives, Karvonen doesn't give the cylinder dimensions, although he does supply the tractive effort. Here the TE was 8,735 lb.

The table shows that 1-4 -- Alutar, Lemminkainen, Ilmarinen, and Suomi -- arrived in 1860. #5 Voima came in 1862 and #6 Pohja was delivered in 1863.


Class A2 (Locobase 5601)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003). Unfortunately, for a number of the early Finnish locomotives, Karvonen doesn't give the cylinder dimensions, although he does supply the tractive effort. Here the TE was 7,208 lb because the same boiler (and most likely cylinders) worked taller drivers

The table shows that Pilvi and Tuuli -- 7 & 8, respectively -- were delivered at the same time.


Class A3 - Lankkihattu (Locobase 5602)

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

Karvonen doesn't give the cylinder dimensions for this class, although he does supply the tractive effort. Here he shows two -- 7,800 lb and 9,800 lb

The class arrived over a long period of time. 11-20 came in 1869 followed by 44-47 two years later. Then came a 22-year gap after which 5 were supplied in 1893 (178-182) and 6 in 1898 (222-227). I suppose that the higher tractive effort refers to the 1890s engines.


Class A4 (Locobase 5603)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003). Karvonen doesn't give the cylinder dimensions for this class, Connelly's Baldwin list supplies that data. See also DeGolyer, Volume 6, p. 170 and

J-E Nystrÿm's railroad website -- [] (2 April 2003, last accessed at [] on 25 December 2014) -- offers short descriptions of Baldwin locomotives procured by Finnish railways. Works numbers were 2998-2999, 3002-3003 in November 1872; 3151, & 3153-3156 in 1873.

This batch of Eight-wheelers, he says, were among the very first American locomotives to make the long trip and were bought by a private line operating between Hango & Hyvinge. All were named: Hyvinge 1, Ekenas 3, Pipping 4, Hango 2, Von Trapp 5, Petrofsky 6, Wimberg 7, Jacoby 8, and Zilliacus 9.

A contemporary photo shows a nicely proportioned Eight-wheeler with a balloon stack and widely spaced front truck axles. That line soon went bust and VR took the line and the locomotives over in 1875. Except for one totalled in 1901 in Finland's first major rail accident, the class served until 1911-1918.

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.


Class A5 - Lankkihattu (Locobase 5604)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003). Tractive effort is given as 7,900 lb

These two locally built variants of the A-3 filled in part of the 22-year gap between the Dubs & Company's major deliveries. The drivers are a little shorter, which explains the slightly higher tractive effort.


Class A6 - Lankkihattu (Locobase 5605)

Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003). Tractive effort is given as 9,800 lb for those using boilers pressed to 142 psi.

After the first batch of Dubs engines in this class had been delivered and two locally built locomotives added, the VR went to Wiener-Neustadt for this baker's dozen. According to Karvonen's table, 90-95 arrived in 1875, while both 59-61 and 96-99 came in 1876. Locobase suspects that 59-61 actually were delivered in 1874.


Class A7 - Lankkihattu (Locobase 5606)

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

Tractive effort is given as 9,800 lb for those using boilers pressed to 150.8 psi. One wonders, however, because the same tractive effort is given for others of this class with 10-bar (142.2-psi) boilers ....

SLM finished off this long-running series of Eight-wheelers by delivering this quartet in 1898. Karvonen gives two tractive efforts (the lower being 9,200 lb), but because we know nothing of the cylinder dimensions, we can't say what factors were different.
