Sir Handel and Peter Sam's secret
- This is a completely revised version of the first theory because now I think the old one is terrible. Let's think about the state of the Skarloey line when Sir Handel and Peter Sam arrived. It was just getting back on it's legs after Rheneas saved it, and said engine was going on an overhaul. Skarloey was just slightly older than Rheneas and stored in the shed. Perhaps the Thin Controller was planning to send Skarloey to be overhauled as soon as Rheneas got back. Of course, Skarloey's overhaul was pushed way forward after he took Sir Handel's passengers home. Two engines are now getting repaired. I doubt it's possible for three engines to be on overhaul at the same time, considering the state of the railway at this point. So, maybe that's why Sir Handel and Peter Sam kept it quiet for a while. And, also the fact that they needed to build up Skarloey and Rheneas' trusts before talking about something this major. Then, of course, Rusty shows up, Peter Sam has an accident, Duncan shows up, Ada, Jane, Mabel, Cora, Gurtrude and Millicent get bought and Skarloey gets home, all at once pretty much. Now, with two new engines on the line and Rheneas not back yet, Sir Handel and Peter Sam have to build up their trusts as well (Rusty, it doesn't take too long because he's so friendly, Duncan... took more time). Of course, the misunderstanding with the TV train doesn't help matters. Rheneas finally comes home the third book centring the Skarloey line, so Sir Handel and Peter Sam have to build his trust up a bit. (Granted, it doesn't take very long, as Rheneas is a lot like Skarloey). And then, about 8 Salon coaches were found and restored from garden sheds, holiday chalets, summer house, you get the idea, and this keeps the works busy (not to mention Godred's story may have scarred Sir Handel so much he couldn't talk about the Mid Sodor Line). By the time Sir Handel and Peter Sam feel like they are up to telling their Mid Sodor stories, the Thin Controller announces that the Duke of Sodor's coming to Skarloey and Rheneas' 100th, and they decide to keep this a surprise, thinking that the Duke they know is coming. However, Duck's words certainly did not help and both engines were guilt stricken thinking they were too late and Duke's dead in a similar fashion to Godred. Then, after much worrying, Sir Handel and Peter Sam revealed who they were, told the engines everything about Duke, he's found, restored and the MSR family is back together.
The Fat Controller is telepathic.
- He can read the minds of the engines and will scold them for a particular mindset after an accident. Case in point being "Thomas Comes to Breakfast" where a cleaner had meddled with Thomas' controls but Thomas had Acquired Situational Narcissism at the time.
- More likely The Fat Controller either never found out about the cleaner, or knew what happened and decided it was more convenient to scapegoat Thomas rather than waste time hunting down and reprimanding the cleaner.
Mrs. Kyndley is Bobbie or Phyllis from The Railway Children
- Mrs. Kyndley saves Thomas and his train from hitting a landslide in front of a tunnel near her home by waving her red dressing gown out her cottage window - just as Bobbie and Phyllis did with their red petticoats. Either one would be about the right age to be the middle-aged to elderly Mrs. Kyndley in 1951, the year in which Mrs. Kyndley's Christmas is set. What's more, Mrs. Kyndley faints once the train is saved, just as Bobbie did. We don't learn what her first name is; one of the television adaptations gave her the name "Kitty", but that could be a nickname. Possibly verges on Contrived Coincidence, but stranger things have happened.
Duck and The Diesel Engine's plot is a deconstruction of the usual Railway Series formula.
- The usual formula of a Railway Series story is that an engine acts pompous or obnoxious, gets shown up or humiliated by an accident or another engine, and then figuratively admits defeat, making no effort to take revenge against the engine who humiliated him/her. This formula is deconstructed in "Duck and The Diesel Engine", as Diesel deliberately antagonizes Duck after Duck tricks Diesel into pulling broken trucks. He doesn't admit defeat like the other engines when he gets shown up. This deconstruction highlights the, at least in Awdry's view, the foreign, disruptive, and dangerous nature of real life diesel engines on real life railways.
There will eventually be a parody version in the vein of Mr. Men for Grown Ups or Ladybird For Grown Ups or Enid Blyton for Grown Ups.
