Since when did the definition of an orbital route mean it had to avoid
Zone 1? Why is it somehow less effective if it does touch Zone 1. I
thought the East London line was supposed to opening up job
opportunities to people - doesn't Bishopsgate count as an area with
jobs?

Basically, if the route did not go through zone 1, it would cost a lot
less! If the orbital route is marginally less convenient but cheaper,
you are a lot more likely to use it than if it is marginally less
convenient but costs the same.

If the boundary did not curve then Shoreditch
would most certainly be in Zone 1 - after all the nearest bus stops on
Bethnal Green Road for routes 8 and 388 most certainly are.

But it costs the same on the bus whatever zone you're in, so that makes
no difference.
