I'm a young, energetic, and professional teacher and writer.
Sometimes these terms are interchangeable. "Ich fahre mit dem Zug" and "Ich fahre mit der Bahn" would be completely interchangeable sentences.
That said, "der Zug" refers specifically and exclusively to the physical train, whereas "die Bahn" can refer to the whole train-system, or to the railway in general. In this way, "der Zug" and "die Bahn" do have different referents.

Also, it can be different in different parts of Germany: some geographical areas are more likely to say "Zug", others call it "Bahn". Also: it's a question of the size of the train: large, interregional trains are mostly called Zug, while smaller ones are more likely to be called 'Bahn" - for the small, regional trains that stop at every haystack we have the beautiful German word 'Bummelbahn'.08/12/20
