Twin Trouble is an Australian VHS/DVD containing eight sixth series episodes.
Join Thomas the Tank Engine and his friends for eight new fun adventures.
- Twin Trouble - Donald, tired of working with his twin, Douglas, volunteers and goes to work with Duck. It doesn't go well at all. When Donald crashes the next day, Douglas races to the rescue. They are friends again.
- Salty's Secret - Salty loves the sea, and is disappointed when he finds his new job at the Quarry. Much to Bill, Ben and Mavis' surprise, he handles the Troublesome Trucks so well that he finishes the job in no time.
- The Fogman - One day in foggy Misty Valley, the fat controller replaces Cyril with a foghorn that is so loud that rocks fall and block the tracks and crush the foghorn. Thomas can't see a thing and crashes but Cyril comes to the rescue.
- Jack Frost - It's freezing and Thomas frightens Percy by teasing him about Jack Frost but James isn't frightened at all. In the dark of night, snow arrives and covers Percy. James sees Percy covered in frost and thinks it's Jack Frost. Frightened, he races back to the sheds but the next morning brags to the others and pretends that he met Jack Frost. Percy exposes his charade and they all had a good laugh.
- Scaredy Engines - It's Halloween and Thomas, Percy and Duck are sent to the Smelter's yard to collect some scrap. But after Edward's spooky ghost stories, Percy is scared and Thomas teases Percy about ghosts. Later, Thomas begins to hear strange noises and sees spooks everywhere. Thomas then apologises to Percy for teasing him.
- Percy and the Haunted Mine - It's competition time for 'The Most Beautiful Station' on the Island of Sodor. On his way to Maithwaite, Percy, scared as usual, sees a chimney and building sink into the ground near the mine. In the end, all is explained.
- Middle Engine - None of the engines like being a middle engine. Being a middle engine causes Percy problems at The Coaling Plant where he is turned upside down!
- James and the Red Balloon - With the arrival of The Hot Air Balloon, James and Thomas are afraid it will take the engines' passenger traffic away. However, they learn that the hot air balloon has attracted so many holiday makers, that their passenger traffic has increased.
