Worldline will be responsible for the installation and maintenance of information screens along with the provision of a central content management system.
The service will initially be provided on the core section of the route between Liverpool Street and Shenfield which will become part of the Elizabeth line when it opens through central London in December 2018.
The new solution will provide a range of localised travel news and assistance information to make travelling on the new line easier.
The solution will display a range of information feeds as well as video content. Station staff will be able to provide localised messaging.
