Thanks to Allan Galanty for highlighting this one and for providing the images.
On 24th November a rockslide occurred on the CN mainline railway track in the Ashcroft subdivision of western Canada. The landslide buried a section of line. removal of the debris to reopen the track will have been far from simple:

There’s a fascinating bit of geology in western Oregon which has totally defied the engineering talent of the State geologists and the best engineers of one of the premiere road building contractors on the U.S. West Coast. The so-called “Pioneer Mountain to Eddyville” stretch of U.S. Highway 20 has been plagued with cost overruns and the destruction of nearly every attempt at bridge building at the crest of the Coast Range:
