Here are some transparent factory gifs that I created to be used as backgrounds for train gifs found on other sites. Feel free to copy the ones you like, and email me so I can see where they are used... To use these gifs, right click on them and save them to your server. Please do not link to them on this server. These will be updated from time to time, so check back for new and revised buildings.
