One day, Tim and his dad went to the park. They saw a big red engine. Tim noticed that the engine looked weak. It was not shiny and new like the other engines.
Tim asked his dad, "Daddy, why is the engine weak?" His dad said, "It is old and needs help to be strong again."
Tim and his dad decided to help the weak engine. They cleaned it and painted it to make it look new. The engine was very happy and became strong again. Now, Tim and his dad visit the engine every week to make sure it stays strong and happy.
