I've been an NWP fan for something like 35 years, but mostly of the south end, below Novato. Lately I've been "exploring" the north end using Google Earth and via great pictures like yours of the Eel River Cyn. That route looks stunningly beautiful! I would love to hike the whole length of that canyon and camp along the RoW some summer.
You posted some great pictures. Would love to see more if you have them, even of yards or other ES facilities. Looks like you had some decent length trains -- in the day.
I see you are in Willits .... me too. I am the Yardmaster at this time. That mostly involves security and minor repair. I also am an employee of the Cal-west, so I am able to get out on the line occasionally.
Jerry, jpg images are definitely a supported format and should just upload automatically, like gif, png, and a couple other image formats. If you want you can mail the image to email@example.com and I can look at the binary source to see if there's any corruption or the like. But in general, if you can see the image in a browser or other image viewing application, it should upload to this network with no problems.
And the "Eureka Southern" album you created for the image above is perfect (album names are completely your choice when uploading your own images, and you can add them to existing albums if they seem a good fit). In the description of your photos you may wish to add that you were the photographer, just so other members know the true source of those images (but only if you like, of course). Regards,
