I got a proper look after work tonight (when there was less fear that I'd
have to wait 15 mins for the next tube....) and yes, it has no exit at
the (south) east end, just an emergency exit. I hadn't appreciated that
if you go to the north end of that passageway, then it goes all the way
round below the London Overground platforms. They must have aims for
platform 10a (and 11) as they have new big staircases (which are blocked
off currently....) which would cope with a few extra people.

Is 10a currently used at all....?

I believe it doesn't get much use at all, but in the medium term they intend
to bring it into regular use, so that more mainline trains can call at
Stratford. Apparently platform 10 will be used bi-directionally, ie as a
second up platform in the am peak, with 10A being used for down calls; and
then in the pm peak 10 and 10A will both be used for down services.

I did hear a few weeks back from one of the NXEA staff on the station that
he thought the Stansted service was going to use Platform 11 rather than 12
at some time in the future as well.
