Neon Cyberpunk Train in the Cavern

Ultra-detailed cyberpunk train speeding through a vast underground cave. The locomotive is sleek chrome with blue and magenta neon lighting, a fusion of maglev and diesel. The cavern walls glisten with mineral veins, stalactites hang from above, and bioluminescent fungi cast eerie glows. Neon signs in alien script and holographic billboards float along the rock faces. Steam vents pulse with warm air while maintenance drones hover around rusted rails. The scene uses high contrast cinematic lighting, foggy air, and reflections on wet stone to create a moody neon-noir atmosphere. Perspective from a low three-quarter view as the train approaches a dark tunnel carved into the rock. Color palette of electric blue, hot pink, emerald green, and deep purple to emphasize the cyberpunk vibe.
