The Scene consists of 3 3D-Objects. The train tracks, the train track screws and the railroad crosstie. The train tracks aswell as the crosstie are made out of a cube. The screw is made of a thorus. I built a left and a right turn, which connect perfectly together to form a semicircle.
The model comes with texturing. I included the texture maps in the project folder and I also included them into the blend file.
This scene is modeled in real world scale. Lighting is set up, ready to render!
