What describes a Grade Crossing?

• A. A road crossing at grade outside the right-of-way.
• B. A street, road, or footpath crossing over track at the top-of-rail level in the exclusive right-of-way area excluding pedestrian crossings at stations.
• C. An underpass below tracks.
• D. A pedestrian crossing within a station platform.

Answer: (B)

A grade crossing is where a street, road, or footpath crosses railroad tracks at the same level within the railroad’s own right-of-way. There is no bridge or tunnel here—the surface of the road and the top of the rails align so trains and road users meet at grade. This description fits the given statement: it specifies a street, road, or footpath crossing over the track at the top-of-rail level inside the exclusive right-of-way, and it notes that pedestrian crossings at stations are not included.

Why the other ideas don’t fit: crossing at grade outside the right-of-way isn’t within the railroad’s property, so it isn’t a standard grade crossing in the railroad sense. An underpass is a grade-separated crossing, which means it’s not at the same level. A pedestrian crossing within a station platform is a different scenario inside the station environment and not a typical at-grade road/footpath crossing within the right-of-way.
