Title: Newcastle upon Tyne
Content:  The city is served by the Tyne and Wear Metro, a system of suburban and underground railways covering much of Newcastle and the surrounding metropolitan boroughs. It was opened in five phases between 1980 and 1984, and was Britain's first urban light rail transit system. The network was developed from a combination of existing and newly built tracks and stations, with deep-level tunnels constructed through Central Newcastle. A bridge was built across the Tyne, between Newcastle and Gateshead, and opened by Queen Elizabeth II in 1981. Extensions to the network were opened in 1991 and 2002.

Content:  The Tyne and Wear Metro system opened in 1980, taking over and improving many of the Tyneside suburban routes that had declined under British Railways management. The underground Central Station for Metro trains was constructed during the late 1970s underneath the main line station, and opened in 1981. Part of the porte-cochère was temporarily dismantled while excavation work took place. The Metro system was a considerable success; Many conventional rail services were transferred there, and several of the east end bays were closed and converted to car parking and other usage. The Carlisle line was diverted to enter Newcastle over the King Edward Bridge of 1906, and a large out-of-town shopping development, the Metro Centre, was opened with a station on that line.

Title: Newcastle, New South Wales
Content:  Like most major cities, the Newcastle metropolitan area has an extensive system of both road links and road based public transport services (bus, taxi etc.) which cover most areas of both Newcastle and Lake Macquarie and which extend beyond the metropolitan area itself. Rail transport, however, is accessible to only a relatively small percentage of the population along the major rail transport routes and ferry services are restricted to those commuting between Newcastle and Stockton. Within the metropolitan area the car remains the dominant form of transportation. At the time of the 2001 Census, less than 4% of the population caught public transport, of which around 2.5% travelled by bus and 1% used the train or ferry to commute to work. On the other hand, over 72% of the population travelled by car to and from work. Newcastle, like all major Australian urban centres, had a tram system, but it was closed in 1950. In February 2019, trams returned to the city with the opening of the Newcastle Light Rail.
