So, those wacky pranksters at TfL have decided that getting from the DLR to the District Line at Bank is an unnecessary luxury in these times of austerity. Which is, presumably, why they've decided to ban such things for a year.
The proposed alternatives are laughable:
Travel from Limehouse to Canning Town to pick up the Jubilee? Go to Mile End to get the District? Quite apart from how far I'd have to go out of my way, are they really suggesting I pay to enter zone 3 in order to get from zone 2 to zone 1?
The most obvious route for me would be simply to leave Bank and walk down to Cannon Street.
Except... that would be two journeys.
So I wrote to them.
It turns out that they're going to make an exception and charge people who leave at Bank and re-enter at Cannon Street within thirty minutes as if they'd only done one journey.
I'm almost tempted deliberately walk really slowly and get a coffee to make the most of my hard-fought-for new rights.
Here's the answer they sent:
Dear Mr Brown
Thanks for your email about pay as you go charges during the current interchange arrangements at Bank.
I'm sorry for the inconvenience these arrangements will cause.
I can confirm that you will be able to touch out at Bank and touch in at Cannon Street without being charged for two journeys. This will be considered as a continuous journey providing you do so within a period of 30 minutes.
I hope this clarifies the position for you and please contact me again if I can be of any help in the future.

Of course, "London Connections" have a nice diagram that suggests some routes might be open.... (don;t tell anyone though...)
