This is the sorry state of the former Eureka Southern Railroad/North Coast Railroad in Eureka California. The tracks have been out of service for many years due to extensive track damage in the notorious Eel River canyon.
The only clearly legible loco number was former SP 2872, a GP9.
I had an interesting thought for a model railroad scenario: imagine if the former Northwestern Pacific had been extended further north, through the very heart of redwood country? I happened to be driving through there a couple weeks ago.
