The only genuine concern that might upset some people is simply that the
interchange at Stratford is going to be somewhat convoluted. The NLL
platforms will be on the north side of the station - platforms 11 and 12
IIRC which is a fair old drag from the current NLL platforms which will
be used by DLR. I do not know if anything is to be done to ease that
interchange with lifts / escalators instead of endless flights of
stairs. Hopefully this issue will be dealt with as effectively as
possible within the limited space and constraints resulting from having
to support the Great Eastern main line.

Couldn't the passenger tunnels be extended to reach them?

Alternatively, what is going to happen to the NLL track under the station
itself? If it's not being used for anything, could that be made a super
passenger tunnel? (and Stratford really does need better access between
platforms at peak hours)
