Agreed, it would be more helpful if there were some more scenic locations. Adding more locations is easy. You just need to know where you want to take a photo from, then on Google maps, imagine yourself looking at the tracks, grab the latitude and longitude of a point on the tracks to your right, then grab the latitude and longitude of a point on the tracks to your left. Next, name a destination or cardinal direction to your right and then to your left. Finally a description of the location you're taking the photo from.

Here's the data format:

var photoSpot1 = {
lat1 : 38.754300811588024,
lon1 : -121.28526449203491,
lat2 : 38.75694465519796,
lon2 : -121.28792524337769,
dest1 : "Roseville",
dest2 : "Marysville",
locName: "East Valley Mainline viewed from Lincoln St.
"
};


Unfortunately, I'm more of an armchair railfan, so I'm not really sure what locations on Tehachapi or Cajon would be good. If someone can provide the some data, I can generate other pages.
