The diagrams

The above image shows many of the features of the diagrams, most notably the white lines representing each track. Other features are detailed below.

Train Describer Berths

This image shows how Train Describer (TD) Berths are displayed on the diagrams. TD Berths are primarily used to display Train Reporting Numbers (headcodes). They are formatted as follows:

* Due to the nature of TD berths just being 4 alpha-numeric characters, signallers can input any four letter code into them. This means that some trains may be mis-labelled, intentionally (e.g. to prevent station information boards showing platform info or to serve as a reminder) or a mistake (e.g. inputting a zero instead of an 'O' or similar), meaning the above formatting is only an estimate as to what the codes represent.

Delays

When the delay mode is activated, the delay of a train is shown in it's description as a colour

Signals

This image shows how signals are represented on the diagrams.

This is another set of signals, now with indications used for shunting and permissive working.


How it works

This website uses the data feeds available from Network Rail. Mainly the Train Describer (TD) feed.

The TD feed provides all the data seen on the main page including the positions of trains down to the signal-level and the state (clear/danger) of many of these signals.
