From the engineering works email sent ouy by TfL today.....
Circle line There is no service on Sunday after 20:00 between Edgware Road and Hammersmith. This is to allow for the movement of engineering trains as part of the works on the eastern sections of the District and Hammersmith & City lines.
That must be an awful lot of engineer's trains......?
I'm guessing that the Circle line will then be running as a complete circle after 8pm? The benefit of this I can see would be to allow one of the platforms at Edgware Road to accommodate an engineer's train and reduce conflicting movements at the Praed Street junction.
The Circle behind the H&C I was on was also running round the circle this afternoon (Circle Line via Paddington on the DB rather than Hammersmith via Paddington as usual) - trains being moved ready for the weekend?
