I work for Entur AS. We are charged by the government with making public transport more accessible in Norway. For this reason we are very interested in making sure the road network, and foot routing network is complete. We are also interested in the public_transport tagging scheme, and any related facilities that might assist a person underway in a public transport journey.
We have offices in Oslo and customer centers in the 5 largest train stations in Norway. Please contact us if you have any questions about Norwegian public transport. You can send such questions to my OSM profile.
