Sorry to bother you, folk

On Sunday morning I need to be in Central London and there are various
train disruptions.

Can someone please confirm how I get from the DLR platform to the
street at Bank.

Haven't been that way for ages because of mobility issues.

And various LT channels don't seem to agree, so I would appreciate
advice from a "real life" user

I can use escalators and lift, but NOT stairs as I'm just recovering
from major knee surgery and on crutches.

If that's tricky, I can go via Tower Gateway, but would like advice.

Thanks much

Ken
