Trains delayed due to ‘nationwide fault’ with comms system
Hardware Issues Disrupt Train Radio Communications

According to National Rail, a widespread issue with the onboard radio communication system utilized by train drivers and signal operators has led to significant interruptions throughout the UK rail network.
The breakdown of the Global System for Mobile Communications-Railway (GSM-R), created for constant digital communication between train drivers and signal operators in places like tunnels that analog systems couldn't reach, was connected to the overnight setup of new equipment at a key telecommunications center in Stoke.
The unmentioned hardware was added during a system upgrade aimed at enhancing the safety of the UK’s railway network and lowering the expenses related to managing a mix of outdated systems.
National Rail explained that the issue, which affected the automated login system of the GSM-R, prevented trains from logging onto their routes at the beginning of service and from logging off at the end.
This led the staff to manually link up using a "wild card" code, similar to a Wi-Fi password, which enabled them to regain contact with the national network. Unfortunately, using this manual method caused delays for many trains, pushing some schedules back by as much as 15 minutes, while others experienced cancellations or changes.
According to the BBC, the smooth and practiced rollout of the manual backup system ensured that there were no critical safety problems during the repair process.
The issue impacted a minimum of ten train services nationwide, such as Great Northern, Northern, ScotRail, Southeastern, Southern, South Western Railway, Thameslink, Gatwick Express, Heathrow Express, and the Elizabeth line.
Even though the issue was resolved in approximately three hours after it was reported, National Rail noted that there could still be some lingering disruptions as they work to get the schedules back on track.
For anyone looking to get reimbursed, it mentioned that passengers should keep their train tickets and jot down details of their trip, as both will help strengthen their claim.
