Looking at my new map of California railroads, I notice an inset map for the Cantara Loop, which is north of Dunsmuir and is where the railroad climbs out of the Sacramento River Valley. It seems in interesting engineering feat, but I've always slept through this part of the route. Should I set my alarm to get up for this?
 
Okay, first thing is that Cantara is not an actual, full, over-and-under loop like at Tehachapi; more of a big, tight horseshoe curve. Team Whooz drove down to it last summer (not easy to find) to check out this site of an environmental nightmare that resulted from a derailment in 1991. Beautiful from the ground, and a good look at the rest of train if you're riding through in daylight I'd guess, but not sure it's something to set your alarm for in darkness.

Interesting. Never knew this existed, despite having apparently ridden through here (asleep) on multiple occasions.
