As a result of its low environmental impact the railway system is the prime candidate to enable domestic and continental mass passenger mobility. One important aspect determining the attractiveness of rail journeys is the thermal comfort that is provided in a passenger rail car. Newer approaches focusing on the improvement of thermal comfort in passenger rail cars are based on the idea to employ personalized comfort zones. It is generally assumed that individual control over indoor climate settings contributes to the passengers’ thermal comfort. The studies presented here further examine this assumption by considering the concept “thermo-specific self-efficacy” (specSE) as psychological construct in the context of thermal comfort in a railway car. Two studies with 11 human subject test runs including 172 subjects in total were performed in a mock-up of a passenger rail car. Environmental climate conditions in the mock-up were controlled and measured. It was found that specSE can be considered as a distinct construct and that it contributed substantially to the prediction of thermal comfort and climate satisfaction. In addition, it moderated the effects of available and exercised control. The presented results expand upon earlier findings for the concept of personal control and confirm the role of specSE for thermal comfort predictions.

由于其对环境的低影响，铁路系统是实现国内和大陆大规模乘客流动的主要候选者。决定铁路旅行吸引力的一个重要方面是客车提供的热舒适性。专注于提高客车热舒适性的新方法基于采用个性化舒适区的想法。通常假设对室内气候设置的个人控制有助于乘客的热舒适。此处介绍的研究通过将概念“热特异性自我效能”（specSE）视为铁路车辆热舒适性背景下的心理结构，进一步检验了这一假设。两项研究包含 11 次人类受试者测试运行，总共包括 172 名受试者，是在铁路客车模型中进行的。模型中的环境气候条件得到控制和测量。结果表明，specSE 可以被视为一个独特的结构，它对热舒适度和气候满意度的预测做出了重大贡献。此外，它还缓和了可用控制和已行使控制的影响。所呈现的结果扩展了个人控制概念的早期发现，并证实了 specSE 在热舒适度预测中的作用。结果表明，specSE 可以被视为一个独特的结构，它对热舒适度和气候满意度的预测做出了重大贡献。此外，它还缓和了可用控制和已行使控制的影响。所呈现的结果扩展了个人控制概念的早期发现，并证实了 specSE 在热舒适度预测中的作用。结果表明，specSE 可以被视为一个独特的结构，它对热舒适度和气候满意度的预测做出了重大贡献。此外，它还缓和了可用控制和已行使控制的影响。所呈现的结果扩展了个人控制概念的早期发现，并证实了 specSE 在热舒适度预测中的作用。
