What I'm saying is that what exactly was the point of the JLE going
from canary wharf - straford when the DLR already did that? Thats not
interchange, thats duplication.

Passenger flows at Stratford are now way in excess of anything the DLR
could carry. Large numbers of workers at Canary Wharf live around the
Hainault loop and change from Central to Jubilee at Stratford - and
equally large numbers from Essex change from NR to Jubilee at Stratford.
The demographics of the area have changed enormously in the last decade
and the Jubilee route sought (quite successfully IMO) to meet those
changes.
