From Henry the Green Engine:
Henry was the focus of Rev. W. Awdry’s irritation once again in the 1990s, when the third season of the television series ‘Thomas the Tank Engine and Friends‘ was released. This series featured a number of original episodes that had not been adapted from The Railway Series stories, some of which annoyed Awdry with their lack of realism. The story that particularly angered him was called ‘Henry’s Forest’.
This episode begins by explaining that Henry’s favourite place on Sodor is a forest through which the line runs. He likes to stop here and admire the scenery. A storm damages the forest, making Henry sad. The episode ends happily, with new trees being planted to replace the ones lost.
Awdry’s complaints were directed at two aspects of the episode in particular. One was that it was unrealistic to have a railway running through a forest, and that sparks from an engine’s funnel could cause a wildfire. Britt Allcroft, the producer of the series, countered this aspect by claiming that she had seen a number of lines do the same thing.
The other aspect was that Henry stops to admire the view without alerting the signalman, which was in direct contravention of British Railways‘ Rule 55. This, Awdry argued, would never be allowed to happen in real life, and would be highly unsafe.
