I don't think I'd bother going that far. Taking over as far as
Hammersmith is probably OK because Crossrail serves several of the H&C's
most important destinations. However, it goes nowhere near Victoria and
is a bit of a walk from places like Monument in the City. We know that
Richmonders don't want Crossrail to replace their District service, and
Ealing Broadway will already have Crossrail.

Good points, against which I have no argument.


Shared running would also be a very poor idea as the trains would be so
different and there would be the inevitable performance pollution.

Shared running would only start east of Turnham Green. Interlining
with the North London Line should not be very difficult. It only has
about 3 to 4 trains per hour. The Piccadilly Line is a real problem.
Perhaps the solution to that would be to have CrossRail also take over
the Rayners Lane service. This would double Piccadilly Line service to
Heathrow.

The problem here is the purchase and demolition of all that has been
built in the intervening years. There is also the issue of the many
differing platform lengths en route to the two termini.

However, if there District Line was reduced to an Upminster to
Wimbledon service plus an Edgware Road to Kensington Olympia shuttle,
Circle Line operation would become simplicity itself!

Crossrail operation would be a lot more complicated, though!

Not really given the minimal amount of shared track, i.e. the NLL. I
don't think this idea is do-able, but it beats turning 24 tph back at
Paddington.
