The FP7s were the WPs power. I think they ran ABB. D&RGW originally ordered a few sets of Alco Ps ABA sets, to pull the Zephyr. The original scheme was the Silver with Aspen gold nose. That soon gave way to the black with gold stripes, That changed to the gold with black stripes. I do not know when they switched to F units, but the PAs got moved to the Royal Gorge and Yampa Valley Flyer.I'm not sure if the Western Pacific and Rio Grande ran similar F3's. I believe the D&RGW ran some FP7A/F7B's.
On the CB&Q the F units didn't last long either. The Q always loved the E units. I was unaware the Q ever had any E6s. I believe they went straight from the E5s to E7s.
I do have a picture of some California Zephyr cars behind a WP 2-8-2. It was pre-delivered cars undergoing trials before the CZ was implemented. But yes the CZ was designed for diesel power. A steamer never pulled it in regular service.
