Sodor Castle, also known as Castle Causeway is an old, ruined castle that stands near the causeway on the Skarloey Railway. It was first seen in the fourth series, but its name was not stated until the seventh series episode, Rheneas and the Roller Coaster.



  • Sodor Castle has had numerous modifications throughout the years:
    • Series 7:
      • The large mountain and pine trees behind the castle disappeared.
      • The design of the castle changed.
    • Series 11:
      • The design of the castle changed again, sharing the same model with the Ruined Castle.
    • Series 18:
      • The mountain and pine trees returned.
      • The design of the castle returned to its original shape.
  • Both of Sodor Castle's appearances in the fifth series were made up of stock footage.
  • In the ninth and eleventh series, the building used for the castle was the same one used for the Ruined Castle.
  • In the seventh series song, The Red Balloon, James can be seen at the castle, but the line running over the causeway is narrow gauge, not standard gauge.
  • In CGI, the castle is represented by a digital matte painting rather than a 3D object.
  • Sodor Castle was used to represent a location on the Mid Sodor Railway in the fourth series episode, You Can't Win.
