Thank you for the links, but those links are not obvious, and you wouldn't find them unless you knew about the closure beforehand, and are familiar with the website.
What is needed is something about the closure on the home page of
www.tfl.gov.uk, where people can click a link to a page giving details of replacement bus services etc.
I am not moaning about the closure itself, even though I will be directly affected as my daily journey to work is from Walthamstow to Kings Cross. Services on the Victoria Line will ultimately be better after the work is done, especially with the Night Tube service starting in September.
However, if TfL want people to plan holidays round the closure, research alternative routes etc. then the publicity needs to be a little better.
Oh, and let's hope that London Overground can sort out the problems they have had with some of the rolling stock on the Liverpool Street to Chingford line before August.
