I doubt that it will be affected other than having overhead
cables and stanchions installed. The bridges which need a
re-build are, I assume, those which go over the railway and
currently do not provide adequate head room.

I rewatched the NR video clip the other day. It shows roughly where
the bridge replacements will be. There's the big one at Upper
Holloway which TfL are already working on. There seem to be one or
two east of S Tottenham - presumably the two knackered bridges over
part of the Lea navigation and then several towards Wanstead /
Woodgrange Park. Most of those latter ones are where the railway goes
over a road given the line is on an embankment. Presumably this just
reflects the fact that those assets are at the end of their life -
like so many other bridges on the line that have been replaced /
upgraded in recent years.

I wonder if, when the platforms are prepared for longer trains, the
entire platform will be re-furbished or only enough for 4-car trains.
Many of the platforms are long enough for 6-car trains. It might
be a short-sighted approach to cater only for 4-car trains.

I think they're only catering for 4 car trains because Gospel Oak
platform can't take a 5 car train so they're not going to be running 5
cars any time soon. I understand no major works are being done at
Gospel Oak given the much shorter blockade period at the west end of
the line. More likely that TfL would up the frequency to 5 tph as they
tend to prefer frequency increases as they drive more patronage and
revenue.

I wonder if the same is planned for the Watford LO service? 4x4 (or even
5x4) cars per hour would be much better than 3x5.
