Bob, at that point it would be north bound. It's physically impossible to be southbound while heading in a northerly direction.
(But we could go round in circles with this one.)
I agree about the circles . In my book, and I don't think I'm alone, the term 'southbound' with reference to railways can have more of an organizational than a geographical meaning. So as the Eurostar leaves the St Pancras, a member of the public would say 'that's a northbound train', but it would be listed as 'southbound' in the time-table.
i think i have got the point but in the end it seems to be quite a polemical issue even for native speakers, right?
thanks a lot,
I wouldn't use those words. "Polemical" suggests some level of violence, and that it's an issue worth fighting about. You're right to think there's a level of disagreement, but my objection was quite tongue-in-cheek, as was the post I was responding to. I wouldn't like you to think that this is a point that native speakers lose a lot of sleep over!
