In 2002, the Tyne and Wear Metro system was extended to Sunderland. The local Metro ends at South Hylton after calling at Sunderland Rail Station and Park Lane Bus Station. Metro trains are quite frequent and travel between Newcastle International Airport and Newcastle upon Tyne in the north and South Hylton at the southern end of the line. However, the Metro extension has not been viewed as a huge success with frequency of services cut due to a lack of demand.
