Data from Markku Karvonen's personal.inet.fi/koti/markku.karvonen/prk/vanha3.htm (visited 29 March 2003).; and Eljas Polho- Pekka Honkanen, Hoyryveturit Valtionrautateilla (The Steam Locomotives of the Finnish State Railways), Suomen Rautatiehistoriallinen Seura Ry (Finnish Railway History Society) 1967-2017. Publishing information supplied by Teemu Koivumaki in a 24 January 2022 email as part of an indispensable series of emails concerning Finnish locomotives. Works numbers were 846-847 in 1868, added 1334 in 1872, 1511-1513 in 1875. Then a long pause ended with 3208-3209 in 1890.
Here the TE was 9,716 lb from boilers pressed to 142 psi; the early engines had 120-psi boilers allowing a TE of 8,360.
An unusual saddle-tank design with the adhesion wheels leading, most likely to permit faster acceleration.
After long careers, the class went out of service in December 1924 (56), July 1925 (53); July, October, and November 1926 (9-10, 151, respectively); September 1927 (150); and January 1928 (54)

A smaller, one-off saddle-tanker used in constructing the Tampella-Nkolainkaupunki railway. As small as it was, the engine endured until it was put out of service, withdrawn and sold in February 1920. Enso OY used it in the Jaaski area until 1925.
