This study examines critical organisational factors and work scheduling in railway freight operators to understand how job-related factors are related to fatigue, health and social well-being. A 148-item questionnaire was developed and distributed to a sample of 276 locomotive engineers and conductors working for the U.S. Operations of a North American Railway. One hundred and twenty-five questionnaires were returned, which was a response rate of 45.3%. Structural equation modeling was performed to identify the relationships between the examined factors. The analytical results of this study indicate that organisational factors and the scheduling system could not be distinguished as two separate factors. The scheduling system is not just the practice of assigning locomotive crewmen to trains, but it is a function tightly connected with other organisational factors. Social Well-Being is an important mediator between Scheduling and Fatigue. Finally, the study revealed a strong relationship between fatigue and health complaints.
本研究考察了铁路货运运营商的关键组织因素和工作安排，以了解与工作相关的因素如何与疲劳、健康和社会福祉相关。研究开发了一份包含 148 个项目的问卷，并分发给为北美一家铁路公司的美国业务部门工作的 276 名火车司机和列车长。共收回 125 份问卷，回应率为 45.3%。结构方程模型用于确定所考察因素之间的关系。这项研究的分析结果表明，组织因素和调度系统不能被区分成两个单独的因素。调度系统不仅仅是安排机车乘务员到火车上的做法，它还是一个与其他组织因素紧密相连的功能。社会福祉是调度和疲劳之间的一个重要中介变量。最后，研究揭示了疲劳和健康投诉之间的强烈关系。
