Since the initial approval of the system from the public, local and national government, and environmental groups, Metrolink has become something of a victim of its own popularity. Many routes are extremely busy, especially at peak times, and prices have risen at far above the rate of inflation. The network has also gained a reputation for being somewhat unreliable. In 2011, Stagecoach Group who operated the Metrolink under contract to Transport for Greater Manchester, sold the contract to the RATP Group.
