Trem a vapor em desenho animado em ponte de montanha na paisagem de outono

Create an ultra-detailed 8K cartoon illustration [9:16 aspect ratio] of the historic Durango & Silverton Narrow Gauge Railroad in Colorado. The scene features a vintage steam locomotive with polished black and brass details, puffing white-gray smoke, traveling along a cliff-hugging track. The train carries vintage passenger cars with red-brown wooden exteriors and large windows showing tiny silhouettes of tourists. The train is traversing a dramatic curved wooden trestle bridge spanning a deep mountain gorge. The gorge walls display distinct geological layers in amber, rust, and tan colors. A crystal-clear turquoise river flows far below, creating white rapids around scattered boulders. The background showcases majestic San Juan Mountains with snow-capped peaks against a vibrant blue sky with a few fluffy white clouds. Rich autumn foliage in brilliant golds, oranges, and reds covers the surrounding slopes with scattered evergreen pines providing contrast. Foreground elements include rocky outcroppings with detailed texture, small wildlife (chipmunks, mountain bluebirds), and delicate wildflowers adding pops of color. Use clean, thin black marker-style outlines for all elements with vibrant, harmonious coloring. Create sharp details in the locomotive mechanics, wood grain of the trestle, mountain textures, and leaf patterns. Maintain perfect perspective with accurate proportions throughout the scene. Avoid any distortions to the train's structure, prevent perspective errors in the track layout, and ensure the bridge maintains logical engineering integrity. Create distinct textures for metal, wood, stone, water, and foliage elements. Lighting should feature warm, late afternoon sunlight casting long shadows and creating a golden glow on the scene, with subtle highlights on the train's metallic surfaces.
