Though LUL contracts Network Rail to signal the line from East Putney

jam of backed up District line trains being held at East Putney so a
diverted SWT service can get down there first).

ITYF that the signalling from Putney Bridge to East Putney is to LUL
standards these days, not NR's.

The signalling is operated by Network Rail and their rules and
operational procedures apply. Maintenance and faults are dealt with by
Metronet (though it was previously sub-contracted out under Railtrack
I believe).

Under the PPP Upgrades there will need to be more frequent trains (so
that the Infraco can get extra money through improving journey times).
One way of doing this is installing the new SSR signalling down to
Wimbledon.
It has not yet been decided if LUL will then take over the operation
of the line.

Also under PPP Upgrades, tripcocks will go, being replaced by ATP.
