End of the Line Bob the Builder : Season 19 Episode 23

The train is almost ready to take to the track on Spring City's new monorail system! Bob and the team are completing one last station before the train's first journey. With Bob test-driving the route, Leo is left to direct the Machines and juggle three jobs at once. Disaster ensues on the site when the roof of the station crashes into the track and bends it out of shape just as Bob is on his way to the station…by train. Leo uses the signal box phone to call Bob, urging him to brake. Bob safely stops the train, and the team work together to fix the track and finish the job in time for the train's first official journey.
