A CONTROL SYSTEM, A METHOD TO OPERATE A CONTROL SYSTEM, A COMPUTER DATA SIGNAL AND A GRAPHICAL USER INTERFACE FOR RAIL-BORNE VEHICLES

摘要

A control system for railway vehicles comprising a plurality of programmable controller (PLC) devices arranged to control signals for railway signalling. Two PLCs (4, 5) are each arranged in an interlocking system to provide a signal to control a signalling operation on at least a part of one or more railway tracks. The PLCs are each connected to at least one communication unit comprising an I/O board, and the interlocking system has redundant software and redundant hardware, and a redundant power supply. In other aspects of the invention a computer program and graphic user interface for carrying out the method are provided.
