My Sad Christmas Train

I am not sure what to do. My Christmas Train, which is the biggest piece to all my Christmas decorations, is on its last legs. All the lights that surround the train are going out. They are rope lights and are all different colors. They are all connected somehow and not easy to just take apart and replace. I have no idea what to do. It's such a cool decoration I would hate to just throw it away. I need to figure out how to fix this. We need the Christmas train to live!
