Yeah, without wanting to sound conceited English is pretty much a universal language. Perhaps Spanish as from experience a lot of people in South America don't learn English as every country in the area speaks Spanish (Or Portuguese). Maybe Cantonese or Mandarin? I really don't have a clue about how many people in Asian countries speak the various languages. I don't see much point in German, French, Dutch etc. as they generally speak better English than us.But which languages would you want the station signage to be in to make it easier for those visiting (keeping in mind the wide-range of tourists who visit the UK)?
