OpenRailwayMap/Tagging in the United Kingdom
This page is a draft and only contains suggestions.
On Network Rail lines, ref=* can hold the Engineer's Line Reference (ELR). For instance ref=MLN1 or ref=BGK. This is usually marked on bridges and level crossings. An ELR and mileage together define a location on the Network Rail network.
Many railways in Great Britain have names ending in “Light Railway” because they were authorised under the Light Railways Acts 1896 and 1921. That doesn’t necessarily mean that they should be tagged railway=light_rail: most of them are operated like main-line railways and should be tagged railway=rail or railway=narrow_gauge.
light main signals (combined) with junction signals (open this image and zoom in)
- suggested: railway:signal:main:states=red;green;yellow;flashing_yellow;double_yellow;flashing_double_yellow Only enter the possible aspects at this signal!
- optional: railway:signal:main:design=individual/combined Does each colour have it's own lamp (older style), or are some of the colours combined into a single lamp (newer style)?
- all tags of the main signal (see above)
- railway:signal:route:design=feather/theatre Only select position states below if design is feather
- railway:signal:route:states=position_1;position_2;position_3;position_4;position_5;position_6;<numbers/letters> Only enter the possible aspects at this signal! For position numbers see figure 6.42 at railsigns.uk.
Limit of Shunt Signals
- railway:signal:direction=backward Limit of shunt usually on the 'wrong' side of the track, so they're backwards from the normal direction.
- Official wording can be found at map by National Rail. Don't copy the map data to OSM, just have a look how NR names the signal types!
