the carriage and hits anyone who sticks their head out with a large shovel. Porter writes a note explaining the situation and places it in Harbottle's empty 'medicine' bottle. When they pass a large station, he throws the bottle through the window of the stationmaster's office, alerting the authorities to their plight. The entire railway goes into action, with lines being closed and other trains re-routed so that Gladstone can finally crash into a siding where the waiting police force arrest the gun runners. After a short-lived celebration, in which Harbottle points out that Gladstone is ninety years old and Porter claims it is good for another ninety, the engine explodes after its hectic journey, and Porter, Harbottle and Albert lower their hats in respect.
