This video from the Gold Line Foothill Extension Construction Authority offers up an introduction to grade crossing design. Why are grade crossings so important? Because they represent the most vulnerable part of any rail line.
The Foothill Extension will make use of state-of-the-art grade crossings to ensure safety along the entire line. The video features animated visualizations that show how quad gates, pedestrian gates, bells and horns all work together to ensure the tracks are clear by the time a train passes.
