I can't figure this out.

I am trying to make a side scrolling train game for 2DWorlds. It will include a train that pulls train cars linked together with ropes, and I might make it into an obby.

I tried to work on it, but I don't know how to do several things on the editor. First I need to know how to make a platform with rotatable wheels. I also need to know how to make the train move by its self. It would be great if some one could tell me how to add a horizontal tiled image to the terrain. Lastly I need some help with adding background audio.
