Dear me, District Dave's forum has banned all discussion about this
thankfully mild collision, and all u.t.l can do is debate the wording of
the press release/report.

The scrape occurred between East Putney and Southfields, on a section of
the District Line that used to be part of Southern Region BR. I
understand that LU now manage the stations, but that the signalling is
still operated by Network Rail. The key question, since it is alleged
that the incident was caused by movement of the track, is who now
maintains the track. LU (ex-Metronet) or Network Rail? And if the
latter, is it as a subcontractor to LU or as owner of the track?

LU is the infrastructure owner of the Wimbledon branch, and maintains it
in house (it's ex-Metronet).

The signalling is still done (under contract) by Network Rail, not sure
what the masterplan is here in terms of the SSL signalling upgrade and
continuing use by NR trains.

What's also going to happen between Harrow-on-the-Hill and Amersham when
they upgrade signals on that line?

The power comes from Network Rail too, but
I think there are plans for it to be provided by LU instead.

When do NR trains run in revenue service on the Wimbledon branch, BTW?

wherever they need to use it as a diversion route

I believe one late night train runs for "route learning" purposes
