You've done a fine job of mapping the New Jersey Transit line. It must have taken you considerable time to create it. I wonder if you realize that you have duplicated information that is already available in the Google Earth Layers (at the bottom: More > Transportation > Rail)? This is a valuable tool for those of us who live in areas which have highly developed public transportation. I use it all the time, and wish it wasn't so deeply buried, or that I could copy it and keep it in my places, the way I have done with the also deeply buried Google Earth Community Layer.
Sorry to toss cold water on your project. Actually, we value people who are willing to take the time to do the kind of careful work that you have done, and I hope you will continue to share with us.
