I think the tile says it all. Check out this amazing video of a train derailed by a ‘small’ landslide. [Source: Landslide Blog]

Rockfall Protection Videos from G.T.S.
More videos! French Company G.T.S. has posted some great videos on rockfall protection systems on their YouTube channel. I don’t speak French, so I can’t give you any more info on the company (although their website looks like it has plenty of info!). But the videos cover the preparation of, drilling for, and installation or rockfall protection fences and barriers as well as a couple of general rockfall ones. They just have video with background music, so no worries about a language barrier. You can watch the installation video below.

Devil’s Slide Tunnel Update and First Attempts to Tame the Landslide
The Devil’s Slide Tunnel project is on schedule and on budget according to a news story at ABC7News.com from earlier in June. The video (shown after the break) has a few nice shots showing rock bolting, soil nailing at the portals, and the geologic mapping and laser scanning that happens at the tunnel face.
I also came across a very neat article about how the Ocean Shore Railroad Company was the first to try to cut into the slope along what is now PCH 1 at the Devil’s Slide back in the early 1900s. They were trying to connect the then rural farming community of Half-Moon Bay with San Francisco. The railroad fought the reoccurring landslide and serious rockfalls. Ocean Shore Railroad went bankrupt in 1922 and pulled up its rails, making room for the current highway. (Photo at left from halfmoonbaymemories.com)
