Single Train of Thought

Isaac loves model trains, and he wants to share his excitement and knowledge with his friends at school. He runs into problems, however, when he tries to convince the school principal to let him start a model train club. His friends aren't interested in joining his club, and the principal doesn't have the time or budget to even think about his idea. To make matters worse, Isaac isn't even invited to share his idea at a school community event organized to introduce students to clubs and activities in their town. Starting a model train club looks hopeless, but Isaac is in for a big surprise.
