Posters placed at central London bus stops direct passengers to the Transport for London website for details of service changes, rather than providing on the spot printed information.
It is possible to download a summary of permanent changes from the website up to two weeks before and up to eight weeks after the planned publication date, but this material is not being updated as claimed. As I write this on 31 May, readers are advised that ‘more information will be provided in the next edition, now due on Friday evening 10 May 2019’.
