Ruter also holds agreements with Entur concerning the regulation of fares on local and regional train services operated within the two counties.

The operation of services is performed by other companies: In 2011, 285 million journeys were made on the Ruter network.

[citation needed] Sporveien is an independent company wholly owned by the City of Oslo.

It owns and maintains the rapid transit and tramway systems, including the rolling stock.

Sporveien also owns Unibuss, which has won many of the public service obligation bids for bus operation in Oslo and Akershus.

The network consists of five lines that all run through the city center, with a total length of 84.2 kilometres (52.3 mi).

The tramway (Norwegian: Trikken) consists of six lines running 131.4 kilometres (81.6 mi), with 99 stops and a daily ridership of 100,000—accounting for 20% of total public transport in Oslo.

It is operated by Oslotrikken, a subsidiary of the municipal owned Kollektivtransportproduksjon, who maintain the track and 72 tram vehicles.

The Ruter tickets are also valid on NSB regional trains, within their geographic area of coverage, which gives more departures to choose from, when going between the most important stations.

The main ferry route connects the peninsula of Nesodden—located on the other side of the fjord of Oslo—with Aker Brygge and Lysaker.

This service was traditionally served by municipal owned Nesodden–Bundefjord Dampskipsselskap, but from 2009 the PSO contract was won by Tide Sjø.

NSB operates both intercity and regional trains to several parts of the country, though these normally have restrictions on transport within Oslo and Akershus.

SL was organized as a limited company owned by the Akershus County Municipality, the City of Oslo and the Norwegian Ministry of Transport and Communications, with a third each.

The companies that operate for SL at the time of the merger was Nettbuss, Norgesbuss, Schau's Buss, Schøyens Bilcentraler, Veolia Transport Norge and UniBuss.
