On another matter, I noticed today that a BBC news bulletin called what I was brought up to call a 'railway station' a 'train station.' I remember first noticing this usage in the 1970s, soon after I moved to London from the Midlands, and from the context then I assumed it was London dialect and that 'railway station' remained the standard term. Recently however I have noticed its use increasing in more formal contexts. A little online research has suggested that it is in fact yet another Americanism. Ah well.
