Maps and Diagrams

Signalling diagrams

The signalling diagrams shown here are similar to those used in signalling centres. Trains are represented by their train reporting number, and you can look these up using the "Search by Identity" feature.

Some train describers send additional data which allows us to display signal aspects and routes set. These maps are indicated by a tick in the "Sig" column.

Please be aware that these maps require a web browser which supports Scalable Vector Graphics (SVG). This includes Internet Explorer 9 and above, Google Chrome, Mozilla Firefox and Safari. Other browsers, such as Opera, may work too, but are not officially supported.
