The stratford issue is very easy to explain.

Thanks for the explanation.


Therefore street to JLE was via one gateline. In order to comply with
the overarching edict the interchange gateline was designed in to cover
the potential for people reaching JLE from "open" stations on the
Central Line, BR and DLR lines.

But surely they can get on from "open" stations elsewhere i.e. at any
other interchange? I don't see why Stratford should be unique.

Stratford was unique because of a policy statement to gate the JLE (a
new piece of railway) off from all other operators. The end result of
that policy only really applies at Stratford and the concept was not
applied at places like Canning Town although we did have some utterly
bizarre gateline designs to assess. I think in the end we convinced
people that the cost far outweighed any benefit. This is what happens
when people have high level concepts and ignore the practical detail.

Similar arguments were put forward when we were designing the gate
layouts for the North end of the Victoria Line. Thankfully we managed to
convince people that such complex layouts would not work and would not
be cost effective.
