"What a silly tank engine, thinking he can beat a fast, modern steam engine like me."
— Connor, Bill or Ben?, seventeenth season

  • Configuration: 4-6-4
  • Designer: Henry Dreyfuss
  • Builder: Alco-Schenectady or Lima Locomotive Works

Connor is a fast streamlined engine from the Mainland Railway, who was designed for speed. He also has his own rake of coaches painted in a similar colour scheme to his own.


Connor is excitable and energetic and, like Caitlin, loves to race the other engines. Connor, however, is better able to be patient unlike Caitlin. Although it is probably unintentional, he can come across as being somewhat smug. Both Caitlin and Connor run regularly between the Mainland and Ulfstead Castle via the Vicarstown Bridge.

Connor helped with the search of Stephen, when the old engine went missing. He was once tricked by Bill and Ben when they challenged him to a race and he almost collided with Henry's goods train after he was trying to beat them.


Connor is a streamlined engine, designed for speed. Along with his friend Caitlin, Connor is an excitable and energetic character, who likes to be busy and loves to race. Both Connor and Caitlin are friendly and eager to get other engines to join in the fun with them. Connor is rather vain and doesn’t like to get messy or dirty. Connor and Caitlin were introduced to the island to bring passengers from the mainland.


Connor is based on a New York Central Railroad Streamlined J3 Hudson.  The J3 Hudsons were built between 1937-1938 in order to do heavy hauling at a greater speed.  All of the Hudson locomotives were scrapped.


Connor is painted teal with light blue and yellow lining.

  • In real life, Connor would be too large for the British loading gauge. However, it seems that he has been re-scaled to avoid animation issues.
  • Connor's Irish-American accent may be a reference to how the New York Central was built by Irish immigrants.
  • Connor's Wooden Railway prototype depicts him as a LNER A4 Pacific, which may have been his original basis.
