  abstract     = {{Efficient energy management is a key challenge for regional train services,<br/>especially when considering the seasonal variation in auxiliary energy demands such as heating, ventilation, and air conditioning (HVAC). This study<br/>explores how adjusting the maximum operational speed of regional trains can<br/>optimize energy consumption without exceeding design limits or necessitating larger battery sizes. By achieving a balance between train speed, available<br/>travel time, and seasonal auxiliary energy needs, the study proposes an approach to enhance sustainability and reduce operational costs. The research<br/>begins by modelling HVAC energy demands under different climatic conditions and train capacities. Using this model, energy consumption for a batterypowered regional train is simulated on two distinct routes: each with unique<br/>drive profile and timetables. The simulations are conducted using MATLAB,<br/>considering the impact of speed adjustments on both traction energy and auxiliary energy requirements. Results demonstrate the significant potential of<br/>speed adjustments to reduce total energy consumption. This approach ensures<br/>that battery sizes remain manageable while maintaining performance standards across different routes and timetables. Furthermore, the findings<br/>highlight the broader implications of speed adjustment on battery lifecycle,<br/>and CO₂ emissions. This research underscores the importance of precise<br/>speed adjustments in achieving optimal performance, cost-effectiveness, and<br/>sustainability in regional rail services.}},
