Triple Crossing in Richmond, Virginia is believed to be the only place in North America where three Class I railroads cross at different levels at the same spot.

At the lowest (ground) level, the original Richmond and York River Railroad was extended after the American Civil War to connect with the Richmond and Danville Railroad, later part of the Southern Railway System, currently part of Norfolk Southern. The line runs east to West Point, Virginia.

The middle level was the main line of the Seaboard Air Line Railroad, now part of CSX Transportation known as the “S” line, just south of Main Street Station. It is planned to become part of the Southeast High Speed Rail Corridor.
