TfL do not advertise bad news or cuts to bus services.

Why not? Any idea whose decision it was to neglect their duty to keep
the public informed?

I can assure you that there is no indication whatsoever that it is a

service have been sent away from London for other duties within First
Group.

Why does it require special buses?
