Photo by Pa/Wire Fast Great Western Railways (GWR) trains to and from Reading will start to return to service after almost a week of disruption. Class 800 series Hitachi trains in use by several train companies, including GWR, were withdrawn from service after cracks were found on Saturday, May 8. GWR cancelled many of its long-distance services, with Hitachi carrying out precautionary safety checks on the trains. Hitachi Rail and train operators, working with the rail regulator, have put in place suitable criteria for the trains to meet before they can re-enter service. Trains will now slowly start to be reintroduced by GWR as and when they are individually checked and approved as safe, with some additional services to return today and more services to follow next week.
