4. I reviewed my design again here and modified the shape of the train and added/deleted some elements (Fig.08).

5. Something I shaped the body with was the Lattice tool, and I kept adding detail until I was satisfied with the results (Fig.09).

6. Once the model of the train was done, it was time to work on the environment. Before the process of modelling, I started to search for the camera and atmosphere inside the sketches of the environment, based on my previous model of the train station. Coming to the underground level of the train station, the function of the environment was the major point I wanted to focus on (Fig.10).

7. For a complex scene I find it useful to apply Display Layer for some of the objects as this can save you some trouble during modelling without mishandling your 3D model. Modeling of the environment was straight forward: some basic polygons with Extrude, Insert Edge loop Tool, Bevel, etc. - to create all the shapes I needed. Here is a quick idea about how some of the curved shapes were created. First I created a polygon and a Curve, selected the face of the polygon and shift selected the curve. I then used Mesh - Extrude to get the shape I needed, in-between refining the shape by tweaking the vertex of the curve (Fig.11).

8. Once the environment was done, it was time for texturing - and a cup of coffee (Fig.12)!

After using the "texture projection" process, I created some snapshots of my UV maps and painted the texture maps in Photoshop based on the UV maps. As usual, I created different sizes of texture maps in Photoshop, and here are some the examples of my texture maps (Fig.13 - 14).
