YMMV / The Railway Series

  • Harsher in Hindsight:
    • In Old Faithful, it's quoted that Sir Handel thinks that Skarloey is the "best engine in the world". Yeah, try picturing that in your mind 15 books later...
      • While on the topic, in Very Old Engines, we see Peter Sam in a state of panic when he hears that engine dukes were scrapped. Skarloey seems to take this as a joke, and we don't know how Sir Handel took the whole thing. What had Sir Handel come to?
    • Small Railway Engines begins by explaining that the Fat Controller has obtained a new source of weed-killing ballast (for which the Small Railway was built): waste stone from a closed lead mine. Considering how toxic lead waste is, one wonders if the Fat Controller had a massive cleanup on his hands after a few years.
    • In Toby The Tram Engine, Henrietta barely escapes being a henhouse. Guess what Bulgy's made into in book 24...
  • Hilarious in Hindsight: Mountain Engines involves an engine who has his name changed to his number which is six who is later renamed Patrick.
  • Iconic Character, Forgotten Title: Commonly called "Thomas the Tank Engine" after the show became popular. It doesn't help the merchandising between the two products sometimes interchanges and some versions of the original novels are even released officially with the Thomas moniker.
  • Nightmare Fuel: Many of the books about scrapping, even Edward the Blue Engine, seem to traumatize steam lovers.
    • Nightmare Fuel Station Attendant: Culdee to Duncan and Sir Handel about Godred in "Bad Look Out," Duke to Falcon and Stuart about No. 2/Stanley in "Granpuff".
  • Ron the Death Eater: An example for a character that didn't appear much, 98462 was stated by Reverend Awdry to have been sent away because he was rude and nasty. In Trainz-based Thomas fan videos, 98462 is often derailed into an Ax-Crazy psychopath named Alfred who murders (or tries to murder) other engines.
  • Values Dissonance: The boys who made James become a Runaway Train are described as being "soundly walloped" by their parents when they are caught.
    • This trope was partly why Christopher Awdry didn't like the story "Drip Tank" due to it involving an outdated phrase, and for this reason, remained unadapted in the TV series (in a book that was created specifically to adapt stories into episodes).
  • Villain Decay / Time Marches On: In the 1960s, books like Stepney the Bluebell Engine and Enterprising Engines dealt with the subject of Modernisation; in the former, Percy goes as far as to demonize controllers on the mainland, only for Awdry to set the record straight in the foreword by saying British Railways officials are not cruel, and are in fact supportive of the preservation movement. Examples are shown in Enterprising Engines among the controllers who helped keep Oliver, Toad, and Isabel safe. In James and the Diesel Engines, published in 1984, a visiting diesel notes that on BR, "steam engines are kept in their proper places, and aren't allowed out on the mainline without special permission". (referring to the red tape surrounding steam-hauled railtours that has only become stricter as the years passed, due to evolving railway safety standards and environmental laws.)
