AFAIK there are two problem locations in terms of long platforms - the
bay at Gospel Oak and South Tottenham because of the point layout and
proximity of a road bridge. Altering Gospel Oak could be very
expensive indeed and South Tottenham is unlikely to be cheap
(depending on the solution). Clearly the rest of the line has had
much longer platforms in the past and many could be brought back in to
use with relative ease. Haringay Green Lanes and Blackhorse Road would
need extensions. Not sure about the Barking bay platform.

I think it would be long enough but have only looked with eyes, not a tape
measure.
