UK rail travel returns to normal after problems with a radio system disrupted the morning commute

LONDON (AP) — British rail travel is returning to normal after problems with a radio system used by drivers and signalers nationwide caused widespread disruption during the morning commute. National Rail, which represents train operating companies, says the fault led to “short-notice” delays Friday and cancellations throughout the U.K. Lines affected included the Elizabeth Line serving London’s Heathrow Airport and the Gatwick Express to the capital’s second-biggest airport. National Rail says the system is now working normally.
