In this paper a simulation model of a light diesel-powered railcar is presented. Model components are adapted from standard Modelica and Powertrain library. The model presented in this work is a starting point of hybrid railcar simulation in Modelica. It turns out, that a number of models that were primary developed for automotive simulations can be adapted to railroad vehicles. Therefore the effort to set up the simulation is moderate. However the shown serial hybrid is the most simple hybrid power train, parallel or power-split hybrids should be investigated in further. Hybrid power trains as increasingly used in road vehicles become more and more interesting for railroad vehicles. Short-distance passenger traffic on non electrified lines is a domain where brake energy recuperation might reduce the total energy consumption significantly. The potential improvement of fuel economy regarding different application settings is evaluated. The simulation gives an idea of the energy saving potential of hybrid power trains even in railroad vehicles. As the simulations with the different control strategies demonstrated, there is a strong influence of the control strategy on the achievable fuel consumption of a predefined vehicle.
