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 author looks at the gradual introduction of high resolution graphics man/machine interfaces in the control rooms with SCADA systems. The involvement of the operators in the design of the system is also described.<
