There will be no Northern or Bakerloo line trains stopping at Embankment for most of next year:

Given the District and Circle will continue to stop, presumably just a pass through should not be permitted on challenge? That said, I suspect that most routes do go through Embankment on the District and Circle (otherwise you are either running to/from Temple or doing it as a double-back). I suspect also that a replanning of some people's routes will be required for next year's Zone 1. (I know I changed at Embankment this year.)

This may well mean a Charing Cross-Embankment run will feature at some point next year.

The All Lines challenge will suffer most, I think. Not even worth attempting next year.

I think it could possibly be worth doing - remember Waterloo to Charing Cross is a non-stop journey so a move like:

Waterloo - Charing Cross Northern
Charing Cross - Piccadilly Circus Bakerloo

could be worth doing.

But then the sheer trouble of the Bakerloo Northern run at Charing Cross means it may be trouble after all...

The Mouse would definitely suffer, and the Bottle would probably suffer too...

Might go for a last few All Line record in early January.

Embankment is open everyone! Now, for want of a Bond Street (and a Gloucester Road, I guess, but that's less important because the District)...

That news article was from 2013! We've had it! Escalators are replaced! Wow
