About '91 SP had a major derailment there. There were tanker cars of chemicals- it was all fucked up. I remember seeing them on the news, one was in the Sacto Rivo.
Sacto's had derailments.
Cajon Pass still has some shit off from that one.
First time I went through California, old man I'd told in advance I was going to go down the West Co on trains said, when you come to CA: "Keep one hand on your billfold and the other hand on your ass."
I told a Freighthopper about that and he thought for a minute. He grinned real big: "Not really sound advice. Keep both hands on something so if the motherfucker turns into a rollercoaster you're not a dead man."
