I used to ride that train route from a few stops south of there to visit my Dad in L.A. 10-15 years ago. Absolutely gorgeous and relaxing train ride. I always wondered when they would have to move the tracks.
Side note, I took the train instead of driving because So Cal and more specifically greater L.A. traffic was/is so horrible. On a decent day, I could make the drive in 2.5 to 3 hours battling traffic. Instead, I often chose the 4-hour train ride for the beauty and relaxation. There were a couple times when there were accidents, like someone trying to beat a train ahead of us across the tracks. Which delayed the train a few hours, but it was still better than driving.
