I haven't listened to WND yet, busy couple days, and I haven't lived in California for about a decade so forgive me if things have changed a lot since then... But I don't believe the metro that runs beat Inglewood is underground. I think they are pretty much all above ground railways. I believe the only underground one is the one that runs to north Hollywood (should be the red line in the map you posted I think, I'm on my cell so it's hard to tell).
