Developments in rail automation have not been the same throughout the industry. Train dispatchers mostly work in centralised control centres today, while train drivers have only been completely replaced by technology in exceptional cases. With the automation of many operational processes, system knowledge has been lost by both train drivers and train dispatchers. Linear methods are not useful for analysing the course of complex events, which is why human factors are included in the analysis (particularly in aviation) as they can be measured and assessed using qualitative methods. As part of a railway research project, test drives were simulated on a driving simulator, to measure situation awareness among train drivers and test the impact of time pressure. The tests clearly show the need for integrated driving and signalling Simulators, which currently do not exist. They would, however, permit studying the work of train drivers and train dispatchers simultaneously. Modelling train tracks for use in simulators requires much effort and expense and is thus a major cost factor. Using video-based data collection instead can considerably reduce this cost burden. No standards have been established to date for the modelling of signal boxes, but the electronic Pi-Tool can be used for this purpose. This generates Petri net-based models for simulations. With the use of integrated simulators, new insights into the impact of human factors on rail operations can be gained, which will contribute to rail safety.
