When we use this language, coming from English, Spanish or Dutch or whatever, we have that as reference. If you would use this language truely, I guess it would mean that you start to think differently about the objects. Maybe the difference between train and car is not that important anymore.
Indeed, we speak of the cars of a train, while a highway truck with several cars attached is likewise called a train. A railway train is literally a train of railway cars. Then there's the cable car, which is not a train although it runs on tracks, but then again, a track car is a race car for race tracks, which a driver might do training with. And all of them could car-rycar-go.
