On the trip’s second to last day, before heading back to San Francisco, we visited the railway line over Donner Pass. It’s a very scenic route, but you need to be there early, I think, to see some traffic. Freight trains didn’t come by, but fortunately the line sees a daily passenger train.
The California Zephyr has left Truckee and is now on its way to the California – Nevada border. The railway line follows the meandering Truckee River on this section.
