Awesome trains! I modeled the same windows for my train.

                                                       Train lights on the front.

                                                       Some cool pipes.

                                             This pipe is curved in a cool way :D 

Some more cool pipes!

                        The render isn't even completed. It took me 20 minutes to render this. I'll figure  how to reduce the render time with Fred. I now have class with him.

I was inspired by the designer Luigi Colani. For reference image I chose this sleek design for my trains. 

                                                          Screenshot from yesterday.
                                                     I applied bump map om the rust.
