Done in 3D Studio Max, using the Box Modeling method. Textures were done in Photoshop. Took me around 3 - 4 hours to create. There are 2 lights in the final scene. The explosion was done using environmental fire effect and by placing a PBomb in the center of the building to help explode it. One link was created for the track, then I made about 40 copies and placed them on a Line PathDeform. The gears were cylinders with 8 or 10 polygons in height, the every other one was extruded.
