Trivia

 * The original release date for the book was 7th March 2011, but it was pushed back until 4th April for unknown reasons.
 * The US publication of the book is shorter and features less than half of the characters than the UK version.
 * Despite not being in the book, several characters are mentioned, such as:
 * BoCo is mentioned on Edward, Bill and Ben, and Donald and Douglas' pages.
 * Scruff is mentioned on Whiff's page.
 * Henrietta is mentioned on Toby's page.
 * Max and Monty are mentioned on Jack's page.
 * Isobella is mentioned on Kelly's page.
 * Toad, Isabel and Dulcie are mentioned on Oliver's page.

Goofs

 * Bill and Ben's page states that their letters SCC stand for Sodor Construction Company, while they actually stand for Sodor China Clay. This was later corrected.
 * Bertie is missing his radiator.
 * Hank and Edward are incorrectly referred to as tank engines.
 * On Diesel 10's page, it says that he chased Thomas and Percy onto the viaduct when it was actually Thomas and Lady. In the US publication, this has been corrected. The UK publication would later correct this mistake.
 * On Harold's page, it says that the Sodor Search and Rescue Centre was built on Misty Island.
 * Rocky is missing his wheels on his page, this is due to the fact he is drawn after one of his Series 10 reference photos, which didn't show his wheels in the picture.
 * Jack's page incorrectly states that he has a bucket at both the front and back, similar to his Series 6 concept art.
 * Colin is incorrectly labelled as a diesel crane instead of a steam crane.
 * Elizabeth is incorrectly labelled as a petrol lorry instead of a steam lorry, regardless of the fact it says she is a steam lorry in the first sentence.
 * Daisy is incorrectly illustrated as a Co-Bo, having ten wheels instead of eight. Her description also states that she has ten wheels.
 * Ashima is described as having a tender.
 * Sir Handel and Oliver are described as having four wheels instead of six.
 * Freddie is described as having eight wheels instead of ten.
 * Arthur's page states that he is the biggest tank engine. However, Belle is actually the biggest.
 * Skarloey's page states that he was being mended for a long time while Rheneas ran the railway by himself when it was actually the other way round.
 * James is missing his coupling rods.
 * Rosie has purple freckles and her make-up is missing.
 * Hurricane is said to be both a diesel engine and a tender engine, when he is neither. Ironically, his real-life basis was rebuilt into a tender engine.
 * Molly is shown to have lipstick.
 * Baz and Bernie are referred to as "rogue engines" in Sonny's description.
