Stratford paltform numbering
 

At Stratford they've started advertising the move of London Overground
to its new platforms upstairs (from January 2nd), and the most
surprising thing is they'll be numbered 1 and 2, the same as the old
platforms downstairs, rather than "12A" and "12B", as they were shown
on the original plans*.

So I'm guessing the platforms downstairs will reopen as 16 and 17,
giving a nice consecutive 13-14/15-16-17 with the Jubilee Line
platforms. On the other hand, the upstairs platforms will be
1/2-12-11/10A-10/9-8/6-5/3-3A-4B/4A (where / is an island). They can't
rationalise them either, as there will be 14 platforms** upstairs and
only numbers 1-12 available. Unless they renumber the Jubilee as
well...

** well, 11 and 10A have no regular service, and 3A will be on the
same track as 3 (Central Line westbound)

1 and 2 makes sense, because apparently one of the main reasons for not
renumbering more logically was that the NR signalling and PIS displays are
integrated so well the NR platform numbering can't easily be altered.
Because the track changes to get into the new LO platforms basically
duplicate the routes into the old 1 and 2, they've presumably provided the
easiest solution.

I came up with a suggested numbering scheme that left the _current_ high
level NR platforms unchanged, but assumed the DLR and LU were changeable,
which resulted in this:

1 DLR high level bay current 4A
2 DLR high level bay current 4B
3 Westbound Central new platform face under construction
4 Westbound Central current platfom 3
5 Up Suburban - unchanged
6 Eastbound Central unchanged
======
7 unused bay
8 Down Suburban unchanged
9 Up Main unchanged
10 Down Mainline unchanged
10A Down Mainline loop unchanged
======
11 Up Lea Valley unchanged
12 Down Lea Valley unchanged
13 NLL bay
14 NLL bay

At a convenient opportunity in a future resignalling 8-10A could become
7 -10, then you would have a logical south to north system on the high
level.

Then why not 15 - 19 or perhaps A - E for the 5 low level platforms, again
making the big assumption that the LU/DLR platform numbers are not integral
with the signalling systems.

IYSWIM!

Ah you beat me to it!

platforms.

Don't the Jubilee Line platforms go the other way? So it would be
16-17-13-14-15?

On the other hand, the upstairs platforms will be
1/2-12-11/10A-10/9-8/6-5/3-3A-4B/4A (where / is an island). They can't

A right fricking mess! And the passageways make it worse - there is no
single passageway linking all the platforms.

No, see the map in my original post. 13 is the westernmost.

Once the NLL platforms open you'll be able to get to all platforms
with regular service from the western subway, as there'll be level
access via them to 12, which is the only one currently inaccessible
from it.

(this changes in a year when the DLR southbound re-opens, and of
course the western subway isn't accessible from the street)
