The Method has not been fixed on Development of Scenario for establishing a various operational strategies of railway systems for now. This is because we haven't developed operational models due to practical time restriction and we have been short of clear understanding of activities and functions. As a result, it is very important and imminent to develop a way of utilizing them. This paper defines the function of electric power supply on rail stock, through which review and get a plan for development of scenarios. It reviews an operation of pantograph by vehicle electric power supply, control of main circuit isolation, processing command of traction or breaking, handling driving directions, setting up voltage circuit for traction and breaking, multiple breaking, breaking control logic, traction control logic, traction request and etc. extends this scenario on the basis of reviewing the relation between functions. The methodology mainly used is that scenario has been derived by applying activity modelling used in systems engineering. The scenario could be reviewable on whether or not it is possible for appropriate systems to be supplied, by the reason that it is used in acceptance test from a view of users. Also, it could be contributing to national safety through participation of a variety of expertise in establishing the strategy of railway system.
