cars for their North London Railway fleet:

I could never understand why they didn't order four-car units for the North
London line from the outset. You only have to look at the loadings on the
313s to see that additional capacity was desperately needed.

How much platform lengthening will be needed? In most cases it will merely
involve reopening sections of platfrom which have been out of use for years,
but lengthening Willesden Junction high level looks as though it will be
expensive.

I'd say lengthening Willesden Juunction high level looks as though it
will be horrendously expensive - possibly out of all proportion.

One hopes that such an extensive piece of work willl be done to allow
at least 8car (two units of of the proposed 4car Electrostars) if not
12car.

That's the main culprit. Quite a lot need little work other than
stripping/resurfacing/drainage cleaning. WJ is the difficult one to squeeze
another car length out of. Even SDO (to use the inner doors only of the end
cars) wouldn't work, due to the siting of the signalling.

Wouldn't it be relatively cheap to lengthen the platforms even
further? With the high level of overcrowding now and even more
passengers using the route in the future, it seems like it will be
needed. 8 coaches seems like a good number indeed.

Longitudinal seating is simply needed on routes like this It might be
slightly less comfortable, but that's not what peak train travellers
will be thinking about. They're just happy to be able to get on.

Getting a 4-coach platform length at Willesden High level will be expensive,
but do-able. To get 8 coaches here, because of the junction with the City
Goods Line, the only place is on a bridge over the WCML. To build it you'd
probably need a lengthy closure of the WCML.

Pardon my ignorance, but what signaling problems would affect the use of
SDO, such as not releasing the doors in the rear coach?

Sorry, I wasn't very clear on that, was I? Willesden Junction will only hold
three cars. With four car units it would not be possible to pull forward
such that the inner sets of doors in the leading and trailing cars were at
the platform and the other sets cut out because of the position of the
station starting signal at the end of the platform. Either that would need
to be relocated or otherwise both sets of doors on the rear car would have
to be cut out (as that would be off the platform) - not very desirable or
customer friendly.

Some of the platforms aren't long enough though, and Network Rail's
timescale for lengthening them is 2010. TfL are presumably quite keen
to get new trains running ASAP, with the switch to longitudinal
seating giving a short term capacity boost.
