Down voting me for discussing something that is brought up frequently is implying a disagreement with me. I said it's not my theory because you don't have a disagreement with me. It's a piece of trivia people may like to know. It also isn't some conspiracy to lie about it. It doesn't change the meaning. It's just people guessing as to what was meant.

In thousands of years if we no longer have trains, people are going to have to guess about what sidetracked meant. Some people may come to totally different conclusions. Discussing alternative interpretations isn't bad, especially when no one is arguing with the underlying meaning. Everyone know what was meant and I've never seen an argument against it. It's just some pieces of trivia that it may have been an idiom (that had the same meaning) that was used at the time.
