P People still make the railway as a mode of transport the main choice for travel. PTKereta Api Indonesia as one of the State-Owned Enterprises that manage the railfreight services in Indonesia continues to strive to increase the service forpassengers, especially in terms of safety to reduce the number of accidents. Thenumber of accidents which low means that the level of safety of railway transportis applied are relatively high. It is used as a benchmark for success for the organizersof freight transport. Researched problems, data the number of accidents in the last3 years is still volatile and has not seen any decrease significantly. This study aimsto identify the various causes of train accidents, design the system dynamicsimulation model for the prevailing conditions, the test models are developed for avariety of options scenario including the safety policy of the railways, as well asprovide a proposal of a new policy to reduce the number of train accidents. Thereare 8 stages in conducting this research. The first stage, the analysis of the problemswith making observations about the behavior of the system. The second stage,designing the conceptualization of the system using causal loop diagrams. The thirdstage, the formulation of the model by entering mathematical equations on themodel. The fourth stage, the simulation model using the software PowerSim Studio10. The stages of the fifth, the verification of the model in two ways, namely theexamination of the indicator of an error on the stock and flow diagram and inputvalues. The stages of the sixth, model validation with these two tests is thepercentage of the mean comparison and the error variance. Stage seven, policyanalysis, and scenario development. This phase generates 3 scenarios. The firstscenario, the increased ability of human resources by 18%. The second scenario,the increased ability of human resources by 18%, as well as improving the qualityof facilities and infrastructure by 15%. The third scenario, the increased ability ofhuman resources by 18%, improving the quality of facilities and infrastructure by15%, as well as improvement of safety regulation of the railways by 20%. From thethree scenarios, the selected scenario is the third scenario. Because in the thirdscenario, zero accident targets and the ratio of accidents is less than 0.025 in theyear 2024. The stages of the eighth, the repair policy of the selected scenario,namely the third scenario.
