CRS, NLC, TIPLOC and STANOX Codes

These systems have codes similar to CRS codes and are used for stations, some junctions and some tunnel portals. As can be seen, not all features have known codes. If you can provide any further details, please contact the editor.

Codes shown on development signalling plans

It can be seen that the codes for Paddington and Liverpool Street (low level Crossrail stations) are the same as that of their Network Rail counterparts 'upstairs'. Abbey Wood, Custom House and Stratford also have the same codes.

Croydon Tramlink

Docklands Light Railway

Manchester Metrolink

These codes applied to stations early in the system's development. It appears that the system has since fallen out of favour, hence the many gaps.

Location	Code

These codes come from an incomplete list of CCTV assets. They form part of a standard naming scheme, though some assets are Metrolink and some are TfGM responsibility. Only tramway and railway assets (or those that might be) are shown here; though the scheme extends beyond these to car parks, bus stations, etc. It will be seen that some codes coincide with those above. This is probably coincidental as the vast majority are very different.

Alphanumeric codes apply to stations only. Two-letter codes also apply to some other assets.
