All the pictures I took from my California Zephyr trip were out the side window and most looked pretty obvious that they were through such. But when I look at other's pictures from the same train, I find lots what appear to be out a window at the rear of the train (and directly down the rails one has just passed); or maybe from an open platform at the rear of the train. On my Zephyr trip I didn't venture rearward beyond the dinning car. Is there such a window normally at the end of the Zephyr or an open platform that one has access to? In August when I'm on the Zephyr again, if it's there, I'd like to make use of it... and if it's not there, how did these people get said pictures?
