Electric trains (KRL) provide services to residents living in Jabodetabek, one of the world's most significant regions. Although KRL is used daily by about 973,366 residents to carry out their activities, some factors influence its usage. Therefore, this study aims to identify the critical elements that affect train services and the patterns of relationships amongst actors to construct a model for long-term sustainability. This study was carried out using the Micmac and Mactor methods. Micmac is a causal structural matrix that can investigate the relationship between parameters in a system. The Mactor technique, on the other hand, is applied to a variety of tactics involving many actors and a set of related interests and goals. The results showed five critical variables for sustainable urban rail service, namely Safety, Capital, Eco monitoring and evaluation, Eco plan, and COVID control are needed. Meanwhile, The General Administration of Railways, Ministry of Transport, and Indonesian commuter train company are two institutions or actors that are very influential in mobilizing the safety of KRL users amid a pandemic to ensure the continuity of train services. This study also finds that critical variables, key actors, and rail destinations strongly influence the sustainability of social, economic, and environmental aspects of urban rail transportation services. In conclusion, this study provides new insight into developing a sustainable urban rail service model in Jabodetabek KRL.
