ABSTRACT
This paper finds an extended set of railway Safety Management System (SMS) goals to manage safety compliance, technological complexities, operational uncertainties and business objectives in a holistic perspective using Enterprise Architecture (EA) approach. It also presents a comparative analysis of EA frameworks for implementation of a railway SMS. We call this system Safety Enterprise Architecture System (SEAS). In the technique, a set of selected capabilities based on the proposed railway SMS goals and system requirements are evaluated from legal, business and information systems perspectives. The SEAS approach establishes that the prevailing new technologies, evolving social realities and changing market dynamics has made the case of railway safety management more complex. Alongside regulatory compliance, it should also mandate explicit goals of standardization, innovation, business transformation, and IT alignment at all levels. It was found that at present not a single EA framework exists that suits the target SEAS approach entirely but the open group standard TOGAF comes closest.
