I have been staying in Humboldt County the past few weeks, and I have seen a lot of old rail lines. They very certainly look like they are no longer in use: Some explanation of where Humboldt County is might make all these pictures make more sense. Humboldt County is about 220 miles north of San Francisco in linear miles, and is currently 300 miles north in highway miles. The terrain in-between is pretty rough. The hills aren't that high, but due to the heavy rain, there are some heavy forests, some fast rivers, and lots of landslides. In the early days of European settlement, the area was looking like it might be much larger. Logging and timber were big business, and the bay was the best harbor between San Francisco and Coos Bay, Oregon. So despite the challenges of terrain, the late 19th century and early 20th century saw railroads between San Francisco and Eureka, California. However, as in many places in the West, the natural resources economy reached its limit, and the railroads couldn't be maintained. (Or, at least, weren't maintained---of course they probably could have been). Much of the rail network has been literally overgrown. Some of it has been converted to trails. Some of it still *looks* like it could function. It is somewhat ironic that in the very early 20th century (1906-1914), using the technology and engineering of the early 20th century, a railroad could be built over challenging terrain, but that in 2019, rail service to a place like Eureka, California would seem impossible. The proposals to remake a rail line have seemed...dubious. Here is a newspaper article about one such attempt: https://lostcoastoutpost.com/2018/sep/12/latest-east-west-rail-scheme-most-grandiose-yet-it/ Arcata and Eureka both still have Amtrak service, but it is a connecting Thruway bus that goes to Martinez. Due to the rough terrain, if you wish to go north from Arcata/Eureka, you have to go 300 miles south to Martinez, before heading northwards on the Coast Starlight. This is the Arcata Transit Center, the current "Train Station" in Arcata. I will be taking this Amtrak trip northwards next week, which I will give a report of.
