By the way, a pure etymological question. I see both you and tiagoantao call it "TGV". Why is this? That is, why use it instead of the authority name "RAVE", or the Portuguese/Spanish/Italian acronym "AV", or the English "HSR"? Is it because the French (and Catalan) acronym "TGV" is commonly used in Portuguese media?
