HAMMERSMITH & CITY LINE: Good Friday 14, Saturday 15, Sunday 16 and
Easter Monday 17 April, no service between Liverpool Street and
Barking. Trains will operate between Hammersmith and Aldgate.

Why is the Circle suspended, but not the Hammersmith & City? Don't
they share tracks?

Well, as a guess, I'd say that as there is no service
between Liverpool Street and Barking, Hammersmith & City
Line trains will fill out the schedule to Hammersmith so
there will be no need and no requirement for Circle Line
trains to provide the same service.

The "Weekend travel information" email says the reason for the Circle
suspension is to test new signalling. Will the Hammersmith & City line
trains run with the new signalling then?

They are running a circular Circle this weekend and a Hammersmith -
Aldgate service; called Circle line on the trains as the H&C doesn't go
to Aldgate!

So, in the clockwise (outer rail) direction, there are two separate Circle
line services! But separate Circle and H&C services in the anti-clock.


The main work is Crossrail work at Whitechapel.

Yes, that makes sense.
