Level crossing 平交道
（重定向自Railway grade crossing）
A level crossing, or grade crossing, is an intersection where a railway line crosses a road or path at the same level, as opposed to the railway line crossing over or under using 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, road through railroad, railroad crossing, and train crossing.
