This is the MTR S-Train serving on one of the train lines in Hong Kong.The train is highly detailed built with real life as-built diagrams. Most parts have their original stacked modifiers so its easy to customise.Recommended to open it in Blender but .obj and .fbx are also provided. I can provide some sort of modification if you cannot use Blender.
