Class 555 trains begin daytime test runs

Metro customers are getting their first chance to see the new trains out on the system as daytime testing gets underway - marking a new major milestone for the 362 million GBP programme. This the next significant step in getting the new Stadler trains ready to enter service later this year.

The daytime testing began on Wednesday 15 May 2024, when a new Metro train operated in the gaps between timetabled services provided by the current fleet on Metro’s coastal route between Newcastle and North Tyneside. It allows for a process known as kilometre accumulation, putting the trains through their paces by simulating customer service, and follows a detailed testing phase which has been talking place during the night.

The public will be unable to get on board the new trains at this stage. Special netting has been fitted to each set of doors to prevent anyone getting on should the train stop at a station. Announcements will also be made over the public address system and Nexus employees will be in the carriages to advise customers the train is in test. 

Stadler is building 46 new Class 555 trains. Two more arrived in April, bringing the total number now delivered up to seven. The company built 23 units so far, half of the total order it is delivering for Nexus. 

Testing of the trains includes 90,000 individual checks. This had previously been taking place overnight when the Metro network is closed. It covers everything from seats and windscreen wipers, to more big-ticket items like brakes, CCTV, doors, wheels, and power supply. There are approximately 19,000 hours of training time, with the first few trains completing 37,000 kilometres of running, as part of the testing phase.
