The Finnish Steam Locomotive Class C1s were typical of the Victorian principles of locomotive design and the British 0-6-0 of the period with inside cylinders and Stephenson link motion. There is a similarity with the NER Class C1 Caledonian Railway 294 and 711 Classes Caledonian Railway 812 and 652 Classes LB&SCR C class and SER O class. The wood-burning smoke stacks and wooden cab sides were installed for Finnish conditions.
