    Distraction and the Use of Modern Communication Devices in the Train Driver's Cab

    Swiss railway companies provide their train drivers with modern communication devices such as cell phones and tablets. The use of these devices is necessary for train drivers to perform their tasks. However, the use of these devices can distract the drivers to an extent not to be underestimated. Increasing irregularities and unsafe actions, including signals passed at danger, can be attributed at least to a certain extent to the distraction of train drivers by these mobile and other digital devices in the driver’s cab. The final goal of this study was to identify appropriate measures to reduce distraction or its consequences without restricting the scope of action of the train drivers or hindering them in the performance of their primary tasks (i. e., safe train driving). We investigated which digital devices and which of their functions in the driver’s cab lead to distraction in what situations. For this purpose, we conducted 14 qualitative observations in the driver’s cab and six interviews with rail experts. Based on the results, we suggested how to address distraction in the driver’s cab from a work psychology and design perspective. To achieve a holistic approach, we developed measures that address the individual driver as well as the design of technology and the organizational processes. The development and validation of appropriate measures was realized in close collaboration with experts of several railway companies. The outcome is a set of 26 preventive and protective measures. Preventive measures aim to avoid distraction, e.g., by restricting irrelevant information from entering the driver’s cab during the ride. Protective measures reduce the negative consequences of distraction, e.g., the feature of manual and temporary suppression of incoming messages. By carefully selecting and implementing these measures, the railway companies can ultimately support their train drivers to use modern communication devices in the driver’s cab safely and sensibly.
