Networked communications: gateway to modern railway signalling

Railway signalling has taken just a few technology leaps in its long history; lever frames, relays, electrified field equipment, and computer based interlockings .. Each of these steps has enhanced the level of control and safety but brought its own set of problems and changes to the industry. Entering the 21st Century, we approach a further leap, this time from the shackles of point to point physical communications to terrestrial and radio based networks. This paper overviews the improvements, the benefits, the pitfalls, differences and safety issues associated with use of alternative communication media including networks and radio for the safety related Railway Signalling environment. It compares and contrasts European ERTMS-ETCS systems with the North American PTS and PTC control systems over ATCS communications. The paper continues to examine the application of these technologies for train control, interlocking and maintenance management in the Australian environment of primarily suburban passenger and long haul freight trains. It identifies some of the issues of applying the technologies from different environments and the ways in which this might be done appropriately. It touches on the benefits and trade-ofts between custom product and standardised commodities products from different suppliers and concludes with suggestions of how this might best be achieved for an Australian solution.
