CGI animation. Ernie, controller of International Underground, is always on hand to help his friends and to get passengers to their destinations safely. He is helped by trains Victoria, Bakerloo, Circle, Jubilee, the twins Hammersmith and City and Ernie's friends Millie and Mr Rails. There are strange noises down at the sheds. The sounds remind Bakerloo of the rumour that a monster was once said to roam International Underground, and Bakerloo suspects it still does.
