It is bedtime, but a young boy and his favorite toy dog are not ready to go to sleep just yet. Instead, they climb aboard his magical toy train and set off on an amazing journey across the world. The night is quiet as they puff along the tracks until they suddenly hear a voice calling out. A large elephant wants to jump on the train because his home in the jungle is being destroyed. As the train keeps rolling, more and more incredible animals ask for a ride. A seal, a crane, a tiger, and even a polar bear are looking for a safe place to escape the dangers in their wild habitats. But the train is getting very crowded, and the boy has to decide if there is room for everyone. Hop aboard this midnight express and discover how one boy and a magical train try to help protect the earth's magnificent animals.
