Dampflok über ein schneebedecktes blaues Bergtal

A majestic vintage steam locomotive pulling teal-blue passenger cars, winding through a dramatic snowy mountain valley, massive sharp-peaked ice-covered mountain towering in the center with perfect symmetrical peak glowing in cold blue light, thick white steam billowing from the chimney blending into the freezing air, heavy snow blanketing the rugged landscape, dense pine trees covered in snow on both sides, cinematic winter atmosphere, deep blue sky fading to lighter horizon, soft golden sunlight piercing through clouds, highly detailed, epic scale, fantasy adventure style, ultra-realistic yet painterly, inspired by The Polar Express and Studio Ghibli winter scenes, 8k, masterpiece, breathtaking, volumetric lighting, depth of field
