However, use of the manual process delayed many trains by up to 15 minutes, while others were subject to cancellations or alterations as a result.The BBC reported that the well-rehearsed implementation of the manual backup system meant no safety-critical issues occurred while the fix was underway.The problem affected at least 10 rail lines across the country, including Great Northern, Northern, ScotRail, Southeastern, Southern, South Western Railway, Thameslink, Gatwick Express, Heathrow Express and the Elizabeth tube line.Although the problem was fixed within around three hours of being reported, National Rail said there may be some residual disruption while timetables are restored.For those seeking compensation, it added that customers should keep hold of train tickets and make a note of their journey, as both would support any claim.Read more about rail network commsPKP Polskie Linie Kolejowe on track for 5G-based railway comms: Polish railway operator teams with coms tech provider for trials of 5G-based railway communications system to replacing legacy system and prepare for technological migration.National roll-out of UK 5G standalone across road and rail could unlock 3bn for economy: Modelling from leading UK operator suggests roll-out of nationwide 5G standalone will transform road and rail travel across the country, saving billions on fuel and boosting productivity through remote working on trains.Telent completes communications systems upgrades at HS1 railway stations: Telent designs and installs data network and management system at four international stations.In The Current Issue:Interview: James Fleming, CIO, Francis Crick InstituteStage is set for legal battles over Big Tech dominanceFive reasons why and when cloud storage is the answerDownload Current IssueGreater industry collaboration will help move customers to the latest tech Cliff Saran's Enterprise blogWhat to expect from OpenUKs State of Open Con 2025 Open Source InsiderView All Blogs
