Chooooo choooo! The Hogwarts Express has arrived in Hogsmeade for the end of the school year. No one can stay at school all summer, obviously, so store your belongings and find a compartment for you and your friends.

This is where the graduating seventh years will reunite with their peers from their final trip across the lake. It's also where the rest of the students (second - new seventh years) converge to get onto the train. The train leaves promptly in fifteen minutes, so don't dawdle!
