“Did you shunt those trucks onto the other line?"
"You said you wanted them on the other line!"
that other line! The other, other line!”
―Donald and Duck

Twin Trouble is the tenth episode of the sixth series.


One day, Donald and Douglas are chuffing down the line double heading a goods train. Further down the line at a level crossing, Trevor is stuck when a wheel from a cart of hay he is pulling breaks off while crossing the line, leaving the hay cart dangerously across the tracks. Donald sees Trevor, but they cannot stop in time and Donald crushes the cart, derailing him but not Douglas. No one is hurt and Donald is able to be put back on the tracks without having to be taken to be repaired, but Donald and Douglas end up blaming each other for the accident. The twins refuse to speak to each other, and when the Fat Controller needs an engine to help Duck at the shunting yards, Donald jumps at the opportunity. Thomas gets worried about this, but the twins do not listen to him as they insist they will work better alone.

At first, Donald enjoys working with Duck, but things soon go awry; Duck does not understand Donald and Douglas' way of working, much to Donald's frustration. Meanwhile, Douglas is doing work on his own, and is beginning to miss his twin. That night, Douglas' driver takes him to visit Donald. Donald snootily asks if he came to say he's sorry, which brings Douglas' bad mood back.

The next day, Donald is also in a bad mood and is not looking where he is going while reversing and - despite a warning from Duck - breaks through some buffers and into a ditch. His driver is cross and claims that this would not have happened if he was working with Douglas. Donald admits defeat and Duck (knowing he is not strong enough to pull Donald back onto the rails) hurries to get help from Douglas. Soon, Douglas pulls Donald back onto the rails. Donald thanks Douglas and tries to make up for their trouble, but Douglas claims he is sorry. Then Donald talks back, claiming he is actually sorry. Duck chuckles and tells them to not have a row on who is to blame for their troubles and to just be happy they are back together. The twins properly make up in the end and, as Duck predicted, are glad to be together again.

  • One of the Ironworks twins, either 'Arry or Bert, can be seen in the widescreen version of the episode.
  • This episode marks Donald and Douglas' only leading roles in the sixth series, and their first since the third series. It is also their first time playing a lead role together since the second series, as all of their leads in the third series were individually rather than together.

  • This marks the watermill's first appearance in an episode since the third series episode, Thomas, Percy and the Post Train.


  • When Trevor cries "Oh, no!" the studio is reflected in his paintwork.
  • Throughout the US dub, Alec Baldwin does not attempt to give Donald and Douglas Scottish accents.
  • The Fat Controller's close-up figure has a small chip on his waistcoat.
  • In the close-up of Donald and Douglas' wheels sliding across the rails, a wire is hanging beneath Donald's cab. Later, when Douglas is shunting just before Duck arrives, a wire is hanging underneath him.
  • In the shot from Donald approaching the cart, a third rail is visible to his right (viewer's left).
  • When the twins crash into the cart, Donald is not seen derailing, but in the next shot, he has been toppled onto his side.
  • When the cart is hit, it is pushed aside and the hay is spilled all over the place. But in the next shot, the hay is falling from the sky all over Trevor, Donald and Douglas.
  • When Donald stops next to Duck, his left eye briefly jiggles off-centre.
  • A ball of fishing line is visible next to the track leading into the ditch just before Donald has his accident.
  • In one shot, Donald is pulled out with his wheels off the track. But in the next shot of him, his wheels are on the track.
  • Just before Donald falls into the ditch, tracks can be seen behind the buffers.
  • When Donald crashes through the buffers, his wheels are still moving for a brief period of time.
  • When Donald says "I have work to do!" Douglas' eyes are wonky.
  • Donald's face is crooked in the scene where he talks to the Fat Controller with Thomas and Douglas.
  • Up until the scene when Duck tells Douglas that Donald is in trouble, his stepladder is missing.
  • Duck's left (viewer's right) eye is wonky just before Donald crashes.
  • When Douglas says "Donald in trouble? I'm on my way!" his right (viewer's left) eye is wonky and wires can be seen below his cab. His eye is also wonky when he is on Gordon's Hill.
  • In the UK dub, after Douglas says "You pulled me, you mean!" Michael Angelis still uses a Scottish accent when saying "argued Douglas!"
  • When the cart is hit it falls on one side of the track, but in the next shot it is on the other side.
  • Just before the scene fades of Henry and Douglas on Gordon’s Hill, Henry and his train come to a stop at the bottom of the hill. When Douglas goes to visit Donald, James is seen passing by with an express train on the middle track. However, that track ends in a wall, therefore James most likely crashed into said wall as the tracks end there.
