Thanks everybody.
As for your version Ron, I'd say that is indeed the best, clearest and most common version, but as usual I am looking about for the roundabout way of saying things.
We say: "an approaching train", but could we say "a train approaching"? One would think we are talking about "the train's approaching".
The approaching train or the train approaching? It seems that the approaching train is more acceptable in the US than in the UK.
