P2 Train Map
From Wikipedia, the free encyclopedia
P2 is named after the class of locomotive designed by Sir Nigel Gresley. It is a train mapping system used in Britain’s mainline railways to assist with the visualisation of train movement data for monitoring purposes.
The P2 terminals which run on standard networked Windows PCs are used to show the position of individual trains which are assigned a four digit alphanumeric running code know as a Headcode or Train Reporting Code. As the train passes along the track, the position is automatically updated on the terminal. By clicking on an individual entry more detailed information about the train service is available. This includes reasons for late running, departure and destination information. The P2 system has been developed by SchlumbergerSema (now Atos Origin) to replace the older SIVS terminals train mapping system that has been in use since the mid 1980’s.
An example of this System can be found in the high realistic freeware Signaling Simulator SimSig.
