High Quality Content by WIKIPEDIA articles! A level crossing (a primarily British term; usually known as a railroad crossing in the United States) is an instance of the at-grade intersection of a railway line and a road or path; that is to say, where the crossing is made without recourse to a bridge or tunnel. The term also applies when a light rail line with separate right-of-way or reserved track crosses a road in the same fashion. Other names include railway crossing, grade crossing, road through railroad, and train crossing.
