There's also the problem of deciding where in central London the
southbound line say would change from being 'up' (which is normally
but not always TO London) to 'down' - away from London.

Where does the up/down orientation change on Thameslink in central London?

Up and Down swap at the former Farringdon Junction, where the line to
Moorgate used to diverge. Services from the north to Moorgate ran Up
all the way, services to Blackfriars still change designation to Down
at the site of the junction.

-------------

However...

Network Rail published plans to change the designations in January this
year, to come into force April 10.

The up/down line changeover is to be at the north end of the platforms
where the third rail ends. Removal of a signalling interlocking equipment
room at the junction has also led to changes to the signalling areas of
control.

4. (I think) Where lines change designation along their length, they
remain with WIND (West/Inner/North/Down) and OUSE (Outer/Up/South/East)
-- so a Westbound track can change designation to a Northbound track
but not to a Southbound track.

An eastbound train heading for Hainault can transfer to either the Inner
or Outer Rail.

Stands to reason.

direction 'forwards' and 'direction backwards' perhaps? ;-)

'Hither' and 'yon'?

Surely 'hither' and 'thither'?

That would be a problem, though not a great one.
Two of the larger exceptions down south to up and down referring to
London are South Wales, where up is up the valley, and former
Midland Railway lines where up is towards Derby.

Thanks, that's very interesting. *Did the Midland definitions of up/
down remain after grouping, indeed if you travel from Trent jk to
StPan, are you still heading down? *Wasn't the former MS&L line was
"up" into Cleethorpes.

Rgds/Ted
I was told that 'up' direction was defined as being the direction
towards the HQ of the founding railway company. Many happened to be in
London, but hence the example of Derby etc.

Thanks, I'd missed that change. I assume that there is still a mileage
change (58 chains from Moorgate = 0 chains for the line through City
Thamelink) at Farringdon Junction.

I think so, I've had another look at the proposal and mileages seem to be
about the only thing not mentioned...

I think there is some mis-understanding about WIND and OUSE, sorry if
I introduced it and not made it clear.

The relation between the four parts of each acronym does not mean a
train cannot change from an OUSE direction to a WIND direction or
v.v..

The relation is that whatever rules when working on track apply to to
WB Inner NB or Down trains, and a variation applies to the OUSE group.

The main point is, every LU track has a designation, but not always EB
WB SB NB as was written a long way back upthread.

It is; a bearing of about 230.

That happens here, too.

The difference is what happens during. In the UK, the common section
has the number of the most major road (only), leading the minor
road(s) to be discontinuous. In the US (and I think in many parts of
Europe?) the common section bears multiple designations.

While this is true, the road signs should show both numbers with the
"secondary" route in brackets to show that one can be reached by a turn
off the other. This is the general convention in the UK for all such
cases. A case I saw recently is near Colchester, where the A120 to /
from Harwich crosses the main A12. Both roads share the Colchester
by-pass and the road is shown as A12 (A120), with the first junction you
encounter with the A120 shown as A120 east or A120 west to help those on
the A12 know which one they need to turn at.

This is used for any situation where one road leads to another important
road. The main road which forms the south-eastern boundary of the New
Forest National Park is the A326. If you leave the New Forest on the
A35 from Lyndhurst, signs for the turn onto the A326 show A326 (M27)
(A36), indicating that you can use the A326 to reach the motorway or the
main road to Salisbury (A36).

But road re-numbering schemes can throw all this out. Can someone who
lives round that part of the world explain why if you look on Google
Maps for Sidmouth (I happen to be going there in a couple of weeks), the
road to it from Sidford is shown on the map display as the B3175, but in
the actual camera shots of the junction the road signs say "A375"?
