Here is my work in progress of a tram i am working on. This project has loooong history since i am working on it in my free time. I am also documenting my progress in my blog on Artstation.
I am now in a texturing phase jumping between Substance Designer, Blender and Unreal Engine.
All paneling work is now done on one side. Panels have tiling textures. Any additional assets you see on the screenshots are using single trimsheet texture.
I can now move on to assets with unique textures, like handlebars connectors, ticket terminal, consoles and other things.
