On Donner Pass, the afternoon is a perfect time for taking a nap. Very few freight trains seem to be using this route, part of Union Pacific’s transcontinental Overland Route: we saw only one eastbound grain train.
Fortunately, the California Zephyr heading to San Francisco was running on time. Right behind the locomotives, a dome car is part of the train. Unfortunately, I have no more details about this car… could it be a former California Zephyr car?
