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.

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.

Not sure i buy that. How far is the junction from the present platforms?

To build it you'd probably need a lengthy closure of the WCML.

Prefabricate the bridge off-site and swing it into position at three
o'clock on a Sunday morning, minimum closure time needed.

Took the words right out of my fingers - if it's good enough for Bishop's
Bridge, it's good enough for the NLL.

More of a problem is inserting it into the NNL without causing chaos the
following Monday morning.

Split the NLL into Stratford - Kensal Rise and Richmond - Acton Central
bits while sorting out the bridge? AIUI, most of the demand is to the east
of WJ anyway. Not ideal, but it'd only be for a fortnight.
