A caboose is a crewed North American railroad car coupled at the end of a freight train. Cabooses provide shelter for crew (conductor and flagman) at the end of a train, who were formerly required for rear-end protection in non-signaled territory, switching and shunting; as well as in keeping a lookout for load shifting, damage to equipment and cargo, and overheating axles.
