This sure brings back some great memories! My brothers and I used to hike the tracks through the gorge many times back in the late '70s through the early '80s.
The first time I hiked to the big trestle, there was a crane car on the spur track next to the old tank car. Also, the semaphore signal was still intact, and there was a small building next to it.
I don’t know what happened to the crane, but the building and semaphore were quickly destroyed by vandals (the scum of the earth!), along with many other things along the tracks. Later on, illegals became a big problem, hiking the tracks to avoid the Border Patrol and leaving lots of trash, starting fires, etc. The timbers in one tunnel were burned out that way, along with a couple of the smaller trestles.
One time we pushed that speeder up the tracks a long ways, then let it coast and rode it back down. That was really cool. Sadly, the next time we were there, the speeder had been pushed over the cliff by vandals.
Some folks used to ride the tracks on homemade carts back then. My brother and I nearly got run over by one of them! We were hiking back to camp shortly after sunset and it was starting to get dark. We hadn’t expected to be gone so long so we didn’t bring flashlights.
As we were crossing a very long trestle with no catwalk, a cart came roaring up the tracks. No headlight, and apparently no muffler either. The engine noise was so loud no one could hear us yelling. We got out as far as we could on the ends of the longest ties and just prayed we wouldn’t get hit. The cart roared past us and never even slowed down. To this day I don’t know if the people on it ever noticed us.
It’s too bad those passenger cars and the caboose were left in the gorge. They’ll be completely trashed before very long.
BTW, the Carrizo Gorge was the inspiration for my layout.
