The VR Class Tr1 is a class of heavy freight locomotive built in Finland and Germany. Before 1942 VR Class Tr1s originally had the class name R1.^[1] They were nicknamed “Risto”,^[1] after the Finnish President Risto Ryti.^[2] They were numbered 1030–1096.^[1]

67 locomotives were built between 1940–57^[1] by Tampella, Lokomo and Arnold Jung Lokomotivfabrik GmbH, Jungenthal of Germany.^[1] The "Risto" is a product of the same era as the express train locomotive Ukko-Pekka (Hr1), and they share a similar appearance as well as several common components. Because of their high tractive effort the Tr1 locomotives were also called upon for passenger service of a heavy intermediate character. Tr1 1096 was the last steam locomotive manufactured for VR in 1957.^[1] Tr1 locomotives were withdrawn during the 1970s, with the last being withdrawn in 1975.^[1]

Two Tr1 locomotives are located in the United Kingdom. One is owned by millionaire railway enthusiast David Buck, while another lies abandoned in a secluded forest in Acton, Suffolk.^[3]
