The original California Zephyr had five dome cars and was timed to allow passengers to see the best scenery in the Sierra Nevada and Colorado mountains in the daytime and to pass through the relatively boring deserts and prairies at night. Amtrak’s Sightseer Lounge car, shown below, is no dome car, but at least the timing has been retained. The Sierras were particularly impressive this trip as there was still a lot of snow.
The problem with the Sightseer Lounge is that, unlike a dome car, it is really hard to see out of both sides from any given seat and, of course, you can’t see in front of you at all. To make matters worse, all but two of the chairs have been bolted in place so that they don’t swivel, which everyone wants to do as the scenery goes by or switches from one side to another. The same thing was true on the Coast Starlight lounge car, so it appears to have been planned rather than just a rusting of some of the swivel chairs.
