Somewhat in response to the inaccurate comments and speculation seen just about everywhere, I provide you this link to a photo with a pretty clear and extensive caption. Also because I've been posting information here about this project since it started construction nearly two years ago.

Amtrak I-5 Derailment

It appears that since I posted the photo, the fatalities have been confirmed to be 3 and that the NTSB has confirmed what I saw on site, that over speed was a (the) major factor. This of course will only lead to more speculation as to why. I just hope that people who are inclined to rush to judgement, will withhold their typing until the NTSB concludes the investigation and makes a pronouncement. For me, I know the engineer to be a fine person and by his co-workers accounts, an experienced and competent railroad employee. I'm certain he's going through hell at the moment.

After I work out the details, I will post a link to a gallery of photos from wreck.
