Specification of high resolution graphics man/machine interface for British Rail´s electric traction power supply network SCADA systems

Control of electric traction power supply networks associated with electrified railways has been a requirement in Britain since the turn of this century. The first electrification schemes lacked remote control facilities, each large sub-station site being manned.

The involvement of the operators in the design of the system is also described
