Did I hear at some point, however, that they may eventually extend ELL out
to Canden town?

Don't think it has ever been proposed officially. The track layout is not
designed to allow for extending the ELL west of Highbury & Islington anyway.
Between there and Camden Rd it is laid out as a two track railway in the
centre of the formation with long passing loops for freight on the outside.
Before the works were slightly reduced, there was a plan for a third
platform at Camden Rd, but this was to allow a Stratford - Camden Rd shuttle
to run.

There are two main reasons it won't happen, IMHO. Firstly, the NLL capacity
is only 8 tph in the peak, and 6 tph offpeak, to allow for the freight
traffic, so there is no room for additional trains from the ELL without
reducing the NLL service. If paths were available, eastbound trains towards
the ELL would have to cross westbound passenger and freight trains trains
from the Stratford direction, this would not allow a robust timetable.
