History

When the VR Class Tve1 locomotives proved to be inadequate in some lineside / traffic applications VR Group decided to order seven similar shunting locomotives from Saalasti Oy. These were more efficient locomotives. One of these was the existing manufacturer's model OTSO2, which it had been supplied to some of the industrial plants. While the further six locomotives were designated OTSO2/VR. The locomotives were delivered during 1964. In 1976 VR Group acquired a further used OTSO2 locomotive, which had previously been used by Kaukas Oy Ab at Lappeenranta. The purchase included a refurbished cabin.[2]

Technology

Tve2 locomotives were configured and sized almost exactly the same as Vr Group Tve1 locomotives. The biggest differences were that the Tve2s were heavier and more efficient Deutz AG 175 hp air-cooled diesel engine.[2] Locomotives numbers 441 and 448 are the only series OTSO2-type locomotives, to differ from the others. They had a different transmission, which gave them a maximum speed of only 20 km/h, when the others have 45 km/h.[3] Some of the locomotives later reported a maximum speed of 50 km/h.[3]

Use

Tve2 locomotives were used mainly in the workshops and depots as well as in public transport hubs, where Tve1's power would have been insufficient. VR Group withdrew all Tve2 locomotives by the 1990s. Last VR Group's Tve2 worked in the North Kuru.[4] One is preserved at the Finnish Railway Museum in Hyvinkää.
