I can't see any reason why they'd diagram in such a way to be 376 only,

asked the question.



My reason for asking was concern that routes limited by platform
length to
8-car trains would see all their peak-period 6- and 8-car trains
replaced by
5-car trains.


Which stations/routes are restricted to 8 cars? I might have been
sensible to have designed the 376s with selective door opening to permit
10 car working to these stations.

What actually is the history of the 12 car networker thing? I recall
lots of platform lengthening happening at about the time the networkers
were coming in, but I wasn't really paying attention at the time? What
work was left undone that would have allowed 12 car trains, and what
were the originally intended routes for them?

I still have the leaflets for the Networker launch. There is talk of
power supply upgrades required (where have I heard that since), longer
platforms, signaling improvements (later followed up by the Dartford
resignal ling. Use of longer trains (up to 12 coach), high power mode,
regenerative braking etc.
