Yup. A highway is generally for cars and trucks and buses, a railway is a railroad line. We might use "railroad" more often though. The word "highway", to me, usually refers to a somewhat larger road with a higher speed limit. For a smaller road with a lower speed limit, I would probably say "road", or possibly "route" if using the numeric designation (county route 573, for example). I might specify if it is a county, state, or federal route. If it is a road in a city, one might say "street" or "avenue". An avenue is usually bigger and more arterial. If we are talking about Interstates (limited access freeways), in the US we can abbreviate interstate to "I". (ex. I-95 runs between Florida to Maine on the east coast) I should know something about this....the Turner-Fairbanks federal highway administration research building in McClean, Virginia is named after my family. The word "highway" can be used in other contexts though. For example, in English in the 90's and early 2000's we used ot say "information superhighway" when talking about the internet. Or, "The rivers were the main highways for the first nation (native american) peoples.". I think the word existed back to at least the 1700's and was used for roads then. There's also the word "turnpike", which usually refers to a limited access toll-road, at least nowadays. For some reason I think we use "freeway and expressway" more when talking about an interstate, autobahn, or autoroute that's in an urban area. At least in my family. I'm really tired right now but I think this is pretty much dead-on (accurate).
