A horse-drawn coach or carriage; an archaic or dialectal term.
From Czech 'kocsi' (a carriage from Kocs, Hungary), which became 'coach' in English. 'Coch' is an older or variant spelling of this word.
The word 'coach' actually comes from a specific Hungarian town—Kocs—which became famous for making really good carriages, so people started calling all fancy carriages 'coaches' from that town's name!
