Software simulation of a Signalbox

This is a software simulation of the inside of a signalbox - showing the track diagram (the area controlled by the signalbox) and includes the points and signals, numbered to correspond with the levers used to operate them. The levers are interlocked, exactly as in the real box on which it is modelled. For two of the boxes modelled, a full sequence of trains is available and the track circuits on the diagram will light up as you give permission for the trains to proceed.

The application is provided with comprehensive information about the process of signalling and how the simulation operates. Context sensitive help messages are available and will appear depending on what is under the mouse pointer, displaying a bubble explaining what the item underneath the mouse does or showing its status. The documentation provided with the application explains the first steps and gives a lot of background information.

The latest version now includes a 'demonstration' mode where it will run through the whole of the timetabled train service provided, with a commentary showing (by a direct demonstration) how an error-free shift can be undertaken.
