Has anyone heard any updates as to what is happening on the Northern Line?
I've been trawling through search engines to find some info, but it all
seems a bit vague.

Some sources say the old arrangement is coming back because of crowding at
Euston and Camden Town. Others say it's not because the present arrangement
works quite well and there are safety concerns after running the old
arrangement for decades without a hitch.

It seems a bit fatalist to write off the flexibility of the Northern Line on
the basis of one incident. At the moment a twice-daily change at Camden Town
or Euston is a sodding nightmare. As usual their website doesn't have much
useful info on it. It's like the whole thing has been swept under the
carpet.
