Are you saying that trains will not actually run in a circle but would

forced to change in order to complete a cross Clapham Junction journey?

That fits in with everything I've read. Its considered impossible to run a
reliable orbital service due to pathing and signalling constraints - a bit
like the circle line really...

I think the S Bahn operators in Berlin might disagree with you. They
seem to run a circular Ring Bahn perfectly well and also schedule
overlap services over parts of the entire circuit to bolster frequencies
and provide links onto radial S Bahn lines. I've used it and it seems
pretty reliable to me and also well patronised.

Circular services are only a problem when you try to run them with
inadequate infrastructure or schedules that are too tight - are that
would be why can't run them in this country then!

I believe thats the background to the T-cup proposals for the circle line
and H&C isn't it?
