Southwestern Yard


The Crenshaw/Los Angeles International Airport (LAX) Transit Corridor Project includes a new light rail transit line from Metro’s Expo/Crenshaw station to the Green Line’s Aviation/LAX Station, eight new stations, and the Southwestern Yard maintenance facility at LAX. The three-story Southwestern Yard will support both lines with four maintenance tracks and capacity for up to seventy rail vehicles. SGH consulted on the fire life safety design for the project.
