'Tube Meltdown' screamed the newspaper headlines as this morning several lines went totally up the wall.
One upshot was that some early-turn Earls Court service control staff were held up on their way to work. Apparently, management decided that it wasn't really worth sending a taxi to get them in, presumably expecting that the night shift would just hang around until their reliefs got there.
They expected wrongly and the night turns went home. So another line went down. Perhaps next time management willpull their finger out and not take people for granted.
