Kristine Valdresdatter, officially known as NSB Cmb17a or Class 17, was a single railcar built by Strømmens Værksted in 1935. The train has a Buda gasoline prime mover with a mechanical transmission. This gave a power output of 90 kilowatts (120 hp) and a maximum speed of 100 kilometers per hour (62 mph). Originally delivered to the private Valdres Line. The Norwegian State Railways (NSB) took over the line in 1937. It was used on the Numedal Line from 1939 and the Grimstad Line from 1947. After a derailment in 1955, the railcar was retired and has been scrapped.

Specifications

Kristine Valdresdatter was a three-axle railcar, with a

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

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]
