Bahn vs Zug
train / move / draft
'die Bahn' and 'der Zug' both have to do with rail transport. 'der Zug' is the specific vehicle you ride in. 'die Bahn' can mean a means of transport such as a train, S-Bahn, or subway, but also the whole system or the company. That is why people often say 'mit der Bahn fahren' when they mean rail transport in general. 'mit dem Zug fahren' is more precise when an actual train is meant. Learners confuse the words because both are often used for travel in everyday life.

Zug
