It's worth remembering that not everyone has the same standard of eyesight, hearing, knowledge of geography, the English language or critical faculties. Many people will be travelling in the UK daily who are not fully familiar with the Latin alphabet, I might well struggle if I was travelling in China, Japan or Russia and a station was renamed in a punning way.
Disability laws mandate train doors be different colours, and on-board information screens have to be changed because they are a few mm too small, that's the reality of the modern railway. With that background is it really appropriate for a TOC to rename a railway station temporarily as part of a film promotion.
I'd be more sympathetic if they'd been promoting a local charity or tourist attraction, or if the pun was genuinely funny. As it was it was simply a PR exercise in order to get press coverage for a commercial partner, which struck me as fairly tawdry.
