A state-of-the-art hydrogen-powered Santa Claus train zips through a star-filled Christmas sky, above residential areas decorated with colorful lights. The design features a dynamic split-wing spoiler, dominant red coloring to match Santa Claus' shirt, laser-etched branding and an integrated LED panel that displays real-time statistics. The train emits a trail of cool steam as it accelerates, while pulsating with dynamic geometric patterns and futuristic sound waves.
