I can just about remember South Ken with 4 District/Circle platforms. What
would be possible, and probably not too difficult, would be to put in an
additional westbound (clockwise)track and platform at South Kensington, so
that District trains have their own track, separate from the Circle, from
here through Gloucester Road. Useful when Earls Court is blocked, perhaps
with trains waiting for a change of driver, as Circle trains could overtake
the queue. Exceptionally a District train could use the Circle track to
overtake a queue if this helped regulating the service.

If the westbound (anticlockwise} track through Barbican was diverted to the
former Up Moorgate Widened line trains would simply call at the other side
of the island platform. The existing westbound line could then be used as a
recess line, or as a turnback line in either direction. At worst passengers
on an eastbound train which was being turned back would be advised to change
at Farringdon if they were travelling beyond Barbican, or have to cross the
bridge at Barbican if they weren't given or didn't heed this advice. No
worse than trains turning back at Mansion House or Tower Hill.


Aha!

Someone understands what I'm on about )

Agreed with all you say. South Ken and Barbican offer as much relief
to the District and Met. using the circle tracks as to the Circle
Line, and Barbican + Moorgate + Aldgate or South Ken + Earls Court +
HS Ken would give them all some serious service recovery options when
things do go astray.
