Claim: The Oslo Port Line was 2.2 miles long, but being located on the streets, it made for a lot of traffic in the City Hall Square in front of Oslo City Hall.
Evidence: The line was 2.2 km long, 1,435 mm (4 ft 8 ⁄2 in) standard gauge single track, but not electrified. The line enabled trains to travel between the two train stations, but the line was located in the streets, making it a delicate task and stopping traffic in the City Hall Square, the plaza in front of Oslo City Hall.
