Transport for London (TfL) and Twitter are piloting a new service alerting passengers of severe delays on London Underground and TfL rail services as soon as they occur.
The world-first service will allow anyone who follows a combination of four existing TfL Twitter feeds - London Overground, TfL Rail, Central Line and District Line - to opt in and receive instant notifications about severe disruption.
Previously passengers had to search through their Twitter timelines for the relevant tweets. Now they will receive a direct message. Timing of the messages can be tailored for when passengers travel.
