Apologies, I meant relation.

One or more running lines are grouped together in to a route - it's
entirely possible for lines that run parallel (e.g. the line from Watford
Junction - Camden Junction runs parallel to the line from Rugby to Euston)
to be in completely separate routes, or for a line to change from one route
to another mid-way.

I'll mull over how to model a change between line names.

Why include the word "code" in the tag name for CRS (and nr_route_code)

TIPLOC stands for Timing Point LOcation Code, so adding 'code' to the end
is technically unnecessary.  STANOX stands for Station Number, so isn't a
code per se.

However, for clarity, I'm happy to make them tiploc_code, stanox_code and
crs_code, or perhaps prefix them with something else.

Thanks - I'll get in touch with him and bounce some ideas around.

The data was released a few months ago in conjunction with their real-time
datafeeds platform (http://datafeeds.networkrail.co.uk/ if anyone is
interested).  That is covered under the T&Cs at
http://www.networkrail.co.uk/data-feeds/terms-and-conditions/, but
separately I've also asked for explicit clarification that the static data
is under this licence and they're happy for the data to be put in to OSM.

I've also asked if they can provide a vector-based version of the INSPIRE
data they've published - FOI request is at
http://www.whatdotheyknow.com/request/map_of_the_railway_network.  I
imagine this will be really useful to validate track layouts and fill in
any gaps.

[Tagging] Tagging GB railway stations and track

2012-11-07 Thread Peter Hicks
All,

I'm part of a group of people who are working to get a richer set of
metadata attached to the railway network in Great Britain, specifically:

  - Tagging railway stations with the three-letter CRS (computer
reservation system) codes, which is widely used by train companies and the
public to refer to stations, plus TIPLOC (TIming Point LOCation) codes -
used in timetable planning - to relevant parts of stations, and STANOX
(Station Number) codes used for train reporting

  - Adding junctions as nodes or closed ways (depending on their structure)
to existing railway lines, along with their TIPLOC and STANOX codes

  - Adding Network Rail route codes to logical groups of routes and tidying
up line names

I've started using three tags - ref:crs_code, ref:stanox and ref:tiploc for
locations, and ref:nr_route_code for route codes - they're attached to St
Albans Abbey station and stations toward Watford Junction as an example.

Does anyone have thoughts or comments on the above?  I've set up a Wiki
page at
http://wiki.openraildata.info/index.php/AddingJunctionsAndSidingsToOsm and
there's a mailing list at
https://groups.google.com/forum/#!forum/openraildata-talk if you want to
get involved.
