Presumably this will all be a bit harder to organise if/when TfL take
full responsibility for the line at some time in the future, such as
at SSL resignalling?

My understanding was that when the Putney to Wimbledon stretch was
handed over to LUL at privatisation, there was an agreement reached
with regards to continuing 'National Rail' use of the line

There was a discussion recently that quoted TfL as saying SWT wouldn't
be allowed on the line after resignalling unless they fitted all their
stock (that might need to use the line) with trip cocks...

I was under the vague impression that the LU SSLs were ditching the whole
trip cock system altogether.

They are. They just put that restriction in to get a rise out of SWT.


I found what triggered that discussion - an article on the District in
Modern Railways (Oct 2007):

"East Putney & Wimbledon. The infrastructure of this outpost of the London
&South Western Railway [1] will be transferred to LU and the SSL signalling
scheme will apply. This in turn will require SWT either to fit all the
trains which it wishes to use on this line with the appropriate equipment,
or to abandon its use altogether."

[1] Network Rail surely!

Based on interview with the District line general manager, apparently...

It'll be interesting to see if they apply the same criteria to the
running of Piccadilly Line trains through Ealing Common.

This a Metronet area (though currently Tubelines deal with faults).
The PPP contract states that inter-running of Piccadilly and District
line trains must be maintaned between Hanger Lane Junction and Barons
Court. How this will work, I don't know!
(However, South Harrow to Rayners Lane has been missed out!)
