(Wow, sliding hillsides in the Santa Cruz Mountains, who would have thought!)
The article describes not only the civil engineering necessary to keep the hill from sliding again, but a very nice map of the area around Wrights, along with the locations of the Sunset Park spur and the existence of a rooming house on the east side of the creek at the future site of the station (post-earthquake). It also mentions that the sand and gravel for the new tunnel came from the gravel pit in Campbell.
Amusingly, academic papers in those days included not only the actual article, but also the question and answer session from what I assume was the conference where the paper was initially presented.
The map also seems to show that the road over to the future station site went under the trestle, so it looks like I modeled that correctly!
