The VR Class Vk3 was originally called the Finnish Steam Locomotive Class I3. The Finnish State Railways ordered three similar classes of locomotives; The American-built Baldwin Class I1s, and the Class I2s and Class I3s, built at Tampella. All were tank locomotives, which did not have to be turned at terminal stations and could run in both directions at the same speed.All the Class I locomotives were used for local transport until the mid-1920s.
