The Norwegian Railway Museum is home to one of the world’s oldest and best preserved vintage trains still in use. Locomotive no. 17 - "Caroline", together with locomotive no. 16, are the two oldest locomotives in the country. No. 16 form part of the main exhibition.

"Caroline" was built by Robert Stephenson and Co. in Newcastle, England, and came to Norway and the Kongsvinger Line in 1861. In 1920, no. 17 was taken out of service and sold to a paper mill.

In 1954, as the railway celebrated its centenary, Norwegian State Railways repurchased the locomotive. With its old name restored, "Caroline" played a central role in the festivities. After the anniversary celebrations, the locomotive was handed over to the museum.

Its compartment-style carriages have no inter-connecting passageways. All the carriages are built between 1878 and 1889, and feature wooden benches - except for the 2^nd class carriage. 2^nd class was the highest standard available in the 1870s, and the carriage offered bolster seats and plush.

The museum's oldest restored goods wagon is box van 1097 built by Skabo in 1889. This box van carries 7 m³ of water in two tanks and serves as a mobile water supply during operating days.

Max. number of passengers is 194.

The train operates on the national rail network, and offers four trips annually. All services run from Hamar to Elverum and back. On some of the trips, the train will stop at Ilseng, Ådalsbruk and Løten.

There will not be any trips in 2011.
