Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003); and DeGolyer, Volume 22. p. 230. Additional information from the animator's railroad website -- [] (2 April 2003) -- gives us Baldwin's works numbers:
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.
Clearly, the VR looked ahead to maintenance and spare parts issues when the supplier was 5,000 miles away. Baldwin's spec noted that the "pistons, cylinder heads & covers, piston rods & metallic packing, and steam chests complete with balanced valves interchangeable with BLW [sic] ten-wheel locos 10-26 Ds. [Locobase 5632]" And "as many parts as possible" of the valve motion were to be interchangeable with "[Baldwin's] heavy Moguls [Locobase 5629]" while the driving axles and "Bones[?]" to interchange with [Richmond-built] light Moguls (Locobase 5630).
Tenders were to be "absolutely" interchangeable with the light Moguls as well. But another note warns "Last tenders built by us [Baldwin] were too heavy at the back end."
Perhaps another example of maintainability's pre-eminence was the surprising injunction to "Try to arrange swell of firebox so the box can be slipped into boiler from below, if it does not sacrifice too many tubes."
The last of these retired in 1959.

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.

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 As with most Finnish locomotives, the fat spark-arresting stack proved necessary to reduce accidental fires in the great swaths of forest through which the locomotives usually passed. Wikipedia reports that birch wood usually served as fuel.
Apparently the heating proportions had been worked out well, as the engines were regarded as good steamers. And they rode well so, Wikipedia adds, "they were very

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.
