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

Point being, if the track was out of alignment, it's solely an LU
matter. I wonder if there's a drainage problem around there - just
south of East Putney where the line curves (next to Keswick Road)
there's a bit of a cutting, though it's nothing dramatic. And just
south of that there's a cut-and-cover tunnel under West Hill (aka the
A3) - maybe it's soggy it there?

They've banned mention of it on DD? Seems a bit OTT, but they do tend
to get a bit jumpy about such things.

I always thought of it as quite a deep cutting when I used the footbridge
over it between Keswick Road and Lytton Grove as a child.
