“…Behavioural observation research involving train drivers began in the early 1970s. Sussman and Ofsevit (1976) observed that train drivers process a substantial amount of diverse information while operating a train, a finding that was corroborated by later studies (Naweed et al, 2018;Hamilton & Clarke, 2005). This information processing was found to be significantly more extensive than previously thought.…”

Background and purpose While the occupation of a train driver can be likened to other transportation professions like truck or bus drivers, it is essential to note that there are distinct hazards exclusive to this role that have a notable impact on the mental and physical well-being of train drivers. The study aims to define personal characteristics, work organisation and work characteristics, professional development and work in general in connection with risk factors among employees who perform the work tasks of train drivers in railway transport. Methodology The study on train drivers in Slovenia was conducted with 179 participants, representing 13.3% of the total population of train drivers. The sample was predominantly male and varied in age, most hailing from the Podravska region. The OPSA digital tool was used to analyse risk factors and gauge psychosocial stress across 17 areas, using a questionnaire split into two sections. Data was collected through online and physical surveys, with voluntary and anonymous participation. Results The study found that the personal characteristics of train drivers do not significantly impact their perception of workplace workload. While professional development factors negatively influenced workload perception, the impact was not statistically significant. However, general work characteristics strongly impact how train drivers perceive their workload. These findings suggest that interventions should focus on modifying general work characteristics to improve train drivers’ work conditions. Conclusions These findings have important implications for the railway industry. They suggest that interventions aimed at improving the work conditions of train drivers should focus on modifying general work characteristics rather than targeting personal characteristics or professional development factors. Future research should explore these relationships and develop strategies to mitigate the identified risk factors.

“…In addition to demographics, age (in years) and gender (1 = male, 2 = female, 3 = other, 4 = prefer not to say), and a series of questions relating to signals passed at danger (SPADs-an incident where the train exceeds the limit of its movement authority and attracts collision risk) 32,33 , respondents completed questions relating to work, sleep, wellbeing, and the impact of these factors on their driving performance.…”

Train drivers work long hours on 24 h schedules and many factors impact their fatigue risk at work, creating a clear imperative for good rostering practice. Adopting a systems approach, this study investigated the relationship between multiple interrelated factors (train drivers’ schedule, sleep, wellbeing, and fatigue) and the perceived influence of these factors on train driving performance and safety using an online survey distributed in Australia and New Zealand. In addition to demographics and work schedule, passenger and freight train drivers (n = 751) answered questions about: (1) Sleep duration; (2) wellbeing, including physical and mental health, the extent to which shiftwork causes sleep, social, domestic, and work problems, and (3) the extent to which ten fatigue, health and wellbeing factors in the work and home environment negatively impact their driving performance. The key factor that emerged from analyses, with the largest and most consistent negative effects (and controlling for other factors) was schedule irregularity. Approved rosters were ranked as having the most important impact on day-to-day driving performance, followed by physical and mental health, and outside work factors. Results also suggested that schedule irregularity may amplify the negative impacts of the roster, impaired physical and mental health, and outside work factors on driving performance. As shift variability and schedule irregularity are often poorly represented in existing industry guidance, these results provide evidence for increased reflection on current fatigue management guidelines for train drivers and suggest a need for greater focus on schedule irregularity through the lens of a systems approach.

“…A lot of research has been done on this specific incident to identify the cause (van der Flier and Schoonman 1988;Punzet, Pignata, and Rose 2018;Yan et al 2021;Naweed et al 2018;Kyriakidis et al 2019). The literature shows that SPAD errors are strongly related to the train drivers' non-technical skills.…”

France's national state-owned railway company (SNCF) plans to introduce the Automated Train Operation (ATO) system in manually operated trains to make train operations more efficient, eco-friendly, and precise. Preliminary Risk Analysis of ATO have been conducted at SNCF, but they are theoretical and have not been validated by humanin-the-loop simulation. As a contribution to the state of the art, we propose to use the PRODEC method to achieve a safety-orientated human-centered and organization-centered design, requiring the development of appropriate scenarios, which constitutes the object of this paper. To this end, our methodology and results are based on i) the analysis and categorization of the incidents that occurred within SNCF during the past years, including their classification, occurrence, and severity; ii) expert judgment. By doing so, we aim to define the human and organizational factors, as well as the technical elements that significantly impact system safety. The ten most relevant scenarios were developed.
