I live about 2000 feet away from the junction between the standard gauge Kongsvinger Line and the narrow gauge steam museum railroad Urskog Hølands Banen.
The museum railroad runs on Sundays (except for charter trips and photo specials), and runs small tank steam engines pulling 3-4 passenger cars, or 7-8 two axle freight cars for photo specials.
On the Kongsvinger Line it is mostly passenger traffic:
Norwegian State Railroads (NSB) running suburban commuter operations from Oslo to Årnes or from Oslo to Kongsvinger on the Swedish border, under contract with the provinces of Akershus and Hedmark. Runs NSB type 69 and NSB type 72 two to four car electric motor units. We might soon see some of the newer and faster NSB type 75 (Stadler FLIRT) EMUs on the longer runs between Oslo and Kongsvinger.
Regional/international traffic operated by the Swedish train company Värmlandstrafik, running every 4 hours or so between the city of Karlstad in Sweden and Oslo, tying the Swedish border region closer into the booming Oslo economy. Runs Swedish X.52 EMUs - known as "Regina" (Queen) sets.
Swedish State Railroads (SJ) long distance international trains between the Norwegian capital city of Oslo and across Sweden to the Swedish capital city of Stockholm, on the Baltic Sea the east coast of Sweden.
Various freight trains operated by various operators, in particular lumber and sawdust trains from the Kongsvinger area (and the forest regions north of Kongsvinger along the Solør RR line), headed down towards Oslo, and then either south to lumber processing plants on the Østfoldbanen RR line - way down along the eastern side of Oslo fjord), or west through Oslo to other processing plants to the west of Oslo or to the export port at Drammen
Intermodal trains with containers (including refrigerators/freezer containers) bound between Sweden or Norway, or bound for the long run up through Sweden to cross back into Norway for the arctic port of Narvik in Northern Norway. The "ore line" between the port of Narvik in Norway and massive iro ore mines at Kiruna in Northern Sweden is connected to the Swedish RR net, but not to the Norwegian.
Car transport trains from the import harbor at Drammen (west of Oslo) bound for Sweden or for Northern Norway (via Sweden)
Freight operators seen: CargoNet (NSB Freight), Arctic Rail Express (ARE), Green Cargo (SJ Freight) and HectorRail

About 50 trains a day on the Kongsvinger line, hoped to be trippled by 2040 if we get priority for double tracking the line from Lillestrøm to Kongsvinger - it currently have only seven places where trains can pass each other - in the RR plans starting around 2020. Before we get to that point there is a lot of other project that have priority - extra tracks between Oslo and Ski to the SE, another double track tunnel and maybe some extra RR stations in Oslo and so on and so forth.
