Specifications
Kristine Valdresdatter was a three-axle railcar, with a bogie at the front and a carrier axle at the back. It had a 90-kilowatt (120 hp) Buda gasoline prime mover with a mechanical transmission. The train was built on a steel chassis with a wood and aluminum body. It had a low floor height, easing entry, giving a low center of gravity and thus better driving properties. It weighed 9.7 tonnes (9.5 long tons; 10.7 short tons) and had a maximum speed of 100 kilometers per hour (62 mph). The overall length was 13.33 meters (43 ft 9 in), and 12.80 meters (42 ft 0 in) without buffers. The train had a seating capacity for 40 plus 5 folding seats in the driver's cab.[1]
History
The class was ordered as the only railcar for the Valdres Line. Built by Strømmens Værksted, it was design-wise similar to the Gullfisk trams which had been delivered to the Oslo Tramway.[2] Kristine Valdresdatter was delivered to the private railway with road number 109. In 1937, the line was taken over by NSB, and the train was given number 18247 and designated Cmb Class 17.[1] As the nationalization resulted in more direct services to Oslo, there was no longer need for the railcar on the line, and it was transferred to the Numedal Line[2] on 21 July 1939. On 12 January 1946, the train was transferred to Stavanger, but was little used. The railcar had a loose tire and procuring a replacement rubber spacer deemed difficult.[3] It was transferred for use on the Grimstad Line[1] on 7 May 1947. On 5 August 1955, the railcar derailed at Fjære, causing a break of axle. The train was therefore set aside, and was decided retired from 7 April 1956.[3] Part of the reason for the early retirement was that the railcar only had a driver's cab in one end, making it difficult to turn.[2] The railcar has been scrapped.[3]
