London Underground's £2.9 billion upgrade raises noise concerns on Piccadilly line

A £2.9 billion upgrade to the London Underground is set to introduce new trains, raising concerns about increased noise on the Piccadilly line. Some existing lines already use partly-automated trains, which can lead to more wear on tracks. Sadiq Khan, chairman of Transport for London, clarified that automatic train operation is not currently planned for the Piccadilly line. The new trains will initially operate with existing signaling systems. Future plans for automatic operation depend on upgrading the signaling and securing funding. Khan noted that noise levels are influenced by various factors, not just automation.
