The board of the Riihimäki–St Petersburg railway divided its orders for freight locomotives between two builders and the second order of thirteen goods engines went to Avonside Engine of England. They were completed in 1869 and numbered 31–43, followed by a further batch of five between in 1873 and 1874, numbered 48–52. These eighteen locomotives were classified C2 in 1885.
Although the C2 class engines were built to the same specifications as the C1 class, several technical details were different as was their external appearance. The most discernible features differentiating them from the C1 locomotives was the sandbox mounted on the boiler (a first in Finland) and ship’s handrail around the running plate, absent on the C1. Nos. 48–52 were of sturdier construction than the earlier engines, making them slightly heavier.
The C2 class had a steam brake that worked on the rear driving wheels and a Nathan displacement lubricator. Oil lamps were used. Originally built as wood burners, the first engines were adapted for coal burning in 1898. Train heating equipment was fitted in the early 1900s and some of the engines had an air brake fitted. By the turn of the century it became necessary to strengthen the frames and replace the boilers; no. 34 (at least) received the wider G11/Sk3 type cab.
When nos. 31–41 entered service in 1869 they were immediately placed on freight and mixed-train duties between Helsinki and St Petersburg. Helsinki, Riihimäki and Lahti depots each had one C2 class engine, Kaipiainen and St Petersburg had two each whilst Viipuri received six. These allocations changed little until the turn of the century. Nos. 48–52 were also used on the same duties, being allocated to depots between Helsinki and St Petersburg.
From 1898 onwards, the C2 class goods engines were dispersed to different motive power depots around the coun-try for branch line and shunting duties, and could be found at Hanko, Turku, Kouvola, Tampere, Sortavala and Oulu. During the First World War they found significant use on railway construction workings and allocated at the nearest convenient shed to the engineering site. In the 1920s, they were confined to shunting duties and permanent way trains.
A St Petersburg shed engine, C2 class no. 36, remained in Russia in 1918 following Finnish independence; it was consequently withdrawn from SVR stock in 1921. No. 49 was damaged in a collision in 1918 and no. 33 was cannibalised for spares after 1919. The rest of the class were all condemned for scrapping by 1929. An extraordinary incident occurred to no. 42 in 1899 while shunting in Viipuri harbour: it collided with a ship.
