Quad Gates (for track speed of 110mph or less)
Quad gates have been shown to reduce collisions at-grade crossings by 98 percent.1
The Authority will work with communities along the rail corridors to install safer rail crossings, such as 4 Quadrant Gates, or Quad Gates. Quad gates are designed to block all lanes of traffic on both sides of the track, and to provide a closure delay on the exit side to allow vehicles that may get stuck between the gates to get off the tracks. Quad gates are also a temporary measure considering the entire high-speed train system is intended to eventually be fully grade-separated over time.
All lanes of traffic are blocked on both sides of the track.
