An orbital route might be a nice to have, but only in addition to the
radial routes, not replacing them. I've mentioned many times that the
trains from the Forest Hill direction are appallingly overcrowded. I
can't see how it improves things to shorten them to fit the ELL and
divert them to Hackney. Even if changing at Canada Water is not
perceived as an extra burden, it doesn't resolve the issue of the
short trains.

Isn't the intention that these are extra trains south of New Cross Gate,
and not replacing the existing service?
