Time for Trouble

Percy's Promise is the second episode of the third season. It first aired on Shining Time Station in the episode Washout in 1991.


Thomas is busy and asks Percy to take the children home from Sunday School. Percy accepts, but when he leaves the weather turns bad and it begins raining.

Percy battles onward, but has to pass through a flooded field and his fire goes out. The crew chop up floorboards from the brakevan and Harold thoughtfully drops hot drinks for them - unluckily landing on Percy's boiler.

Percy makes it home safely and is lauded by Thomas, the passengers and the Fat Controller.




  • This episode is based on the story of the same name from The Railway Series book, Percy the Small Engine.
  • In the restored version, the shot of Percy arriving at Elsbridge with Annie, Clarabel and the brakevan is replaced by an extended shot of Thomas waiting for Percy.
  • In a rare picture, Edward is wearing his exhausted face instead of his concerned face when he talks to Percy at Elsbridge.
  • The Italian title of this episode is "Rescue". In Japan, this episode is called "Percy and the Floods". In Wales, the title for the episode is "Promise Percy".
  • There are noticeable differences in the set between the original and the restored episode when the narrator says "Children love the seaside".
  • Deleted scenes from the first season of Thomas on Toby's Old Tramway are used at the beginning of the episode.


  • At the beginning of the episode, Thomas is on Toby's old tramway.
  • When the narrator says "the river was rising fast", it is obvious that the water for the river is coming from a pipe.
  • When Percy plunges onto the flooded tracks, water appears to come above his firebox. However, in the next shot, the water is below the buffers.
  • Why did Percy use a brakevan for the guard instead of Clarabel?
  • In a deleted picture, Percy's roof is lifted.
  • This episode should have come before Percy Takes the Plunge, as the events of this episode were mentioned in the other.
  • When the driver and fireman bring the floorboards to Percy's cab, they drag them through the water, making them wet.
  • When Thomas is on Toby's old tramway, Clarabel is facing the wrong way. Then in the next shot, Annie is facing the wrong way.
  • Despite the fact that the water only reached Percy's footplate, he has a water line across his boiler when he meets Thomas at the end of the episode.
  • When Percy says "Ugh!", his face is tilted slightly.
  • Thomas leaves Annie and Clarabel with Percy because he's busy with another train that evening, and yet, he's shown pulling different coaches at the end. Shouldn't Thomas have taken Annie and Clarabel, since they are his personal coaches, and left Percy with the other coaches if they were both taking passenger trains anyway?
  • In the shots of Percy in the floodwaters, there is a small speck of dirt on the side of his saddletank.
