On March 29th 2024, Virtual Railfan captured Amtrak's California Zephyr backing through the Big Ten Curves on the Moffat Tunnel Subdivision due to a rockfall of large boulders on the tracks near Tolland, CO. Seeing as how we model that subdivision, we decided to recreate it, and while it's not an exact recreation, it was a lot of fun to recreate what happened. Enjoy!
