Duncan and the Old Mine

"That looks like a good place for an adventure!"

- Duncan

Duncan and the Old Mine is the twentieth episode of the ninth season.

Plot
Duncan is looking forward to taking holidaymakers to see the Culdee Caves when his job is given to Bertie instead. Mr. Percival wants him to deliver coal trucks to the Transfer Yards with Rusty as the machines at the coaling plant have broken down. On his way to the coal mine, Duncan sees an old line leading towards some bushes and ignoring Rusty's reminder that they have work to do, he goes down the old line which leads to an old mine entrance. Carelessly, Duncan crashes into a roof support, causing the entrance to collapse behind him. Duncan carries on into the mine until he hits something, which he thinks are buffers - until he hears a squeaking noise and realises that he ran into some coal trucks. Pushing the coal trucks, Duncan finds that the mine shaft was actually a mine tunnel when he arrives at a bordered-up exit and then he pushes the trucks out of the mine. Rusty, who had been looking for Duncan, finds him with the coal trucks, so they take them down to the Transfer Yards where Mr. Percival tells Duncan that he must think clearly when he wants to have another adventure.
