A generational step change is coming down the tracks for Newcastle upon Tyne. The north of England city is on the cusp of a much-anticipated revamp of its ageing Tyne and Wear Metro light rail network. Some of the city’s famous late night revellers may have already spotted the shape of things to come. The first new Stadler Metro train has successfully completed its first test run on the network as part of the detailed preparations to get it ready for entering service at the end of the year. The operators, Nexus, say that the test went smoothly and that the new train had performed well.
