Due to climate change, the importance of renewable energy is growing. The proportion of non-electrified rail lines is relatively high at around 48% in Europe. Straight secondary connections such as the Traisentalbahn are included. For this reason, they are driven by diesel locomotives. Every year, 65,000 t of goods are transported on this route. Since there is a cogeneration plant on the line and this could potentially provide cheap steam, it is obvious to use this as drive energy. Steam-powered locomotive propulsion systems are rather unusual nowadays. For this reason, steam-based actuators are being investigated in this work. More specifically, the steam engine, the steam engine and the steam turbine are examined for their technical suitability and their economy. The focus is on the design of the gradient storage, on the calculation of the specific steam consumption and on the cost allocation in operation. In addition, the discharge of the slope memory is simulated under realistic conditions.
