'Waggon' is often described more precisely by a defining word in order to make the type of car clear, e.g., 'Personenwaggon' (passenger car), 'Güterwaggon' (freight car), or 'Schlafwaggon' (sleeping car).
Der letzte Waggon des Zuges war ein Güterwaggon.
The last car of the train was a freight car.
Pay attention to the preposition 'in' and the case: 'in den Waggon einsteigen' (to get into the car; accusative for direction) and 'im Waggon sitzen' (to sit in the car; dative for location).
Die Passagiere stiegen schnell in den Waggon.
The passengers quickly got into the railcar.
Common verbs in connection with 'Waggon' are 'einsteigen' (to get on/in), 'aussteigen' (to get off/out), 'umsteigen' (to transfer/change trains), as well as the technical terms 'ankoppeln' (to couple/attach) and 'abhängen' (to uncouple/detach).
Am Bahnhof wurden zwei weitere Waggons an den Zug angekoppelt.
At the station, two more railcars were coupled to the train.

'der Zug' and 'der Waggon' both belong to the topic of railways, but they do not mean the same thing. 'Der Zug' is the whole vehicle or the whole unit that moves. 'Der Waggon' is only a single car within a train. Learners can easily confuse the words because in both cases you see a vehicle on rails. Remember: you get on the train, but you sit in a specific railcar.
