Does anyone know why not? I distinctly remember hearing Ken Livingstone
in his day saying that the London Overground would provide London for
the first time ever with a circular service through the suburbs. He
quite obviously saw the London Overground as a kind of Outer Circle
Line.

Currently we have services from New Cross etc terminating at Highbury
And Islington while other services from Stratford go through Highbury
And Islington to Clapham Junction. Why is this arrangement better than a
straightforward Outer Circle system?

Practicality and customer demand. Joining the SLL and WLL would mean
missing Clapham Junction, a major traffic objective. Westwards from
Highbury to join ELL and NLL is possible (current track arrangements
notwithstanding), but would be an operational nightmare given 7½
minute services on each and a lot of freight on the latter. And the
major traffic objective for the ELL is Highbury & Islington with its
Victoria Line and GN Electrics connections.

All the lines are shared with other services, some of which permeate
far into the Home Counties and bring all their operational baggage
with them. You really don't want to perpetuate all the accumulated
delays in a circular service. Circular itineraries propagate any
problems indefinitely around the service, which is why even the Circle
Line has been de-circlified.

The projected service pattern is the best one to fit travel patterns
and operational practicalities. Onward connections at Clapham
Junction will be as easy as possible – just shuffle down the
platform. At Highbury, either cross-platform or over a short bridge.
