The fundamental component of a hybrid train system is the hybrid power-coupling mechanism. This paper proposes a single-row star-row power-split arrangement for the power-coupling method in a hybrid train. In order to create input and output power-split configuration schemes for a hybrid train power mechanism, a graphical–theoretical model and a relationship matrix were first established. An electromechanical path power proportion equation was then established to filter out two input power-split configurations. The working states of three developed hybrid power-coupling mechanism schemes were studied to find the scheme that fulfills hybrid train design criteria to meet the power, operating mode, and spatial structural arrangement requirements. Finally, by creating a simulation model for the entire vehicle, the dynamics, battery state of charge (SOC) value, and overall vehicle efficiency for the configuration were simulated and examined. The findings demonstrate that the single-row star-row power-split design technique presented here significantly enhances the train performance.
