First, let me identify what engines actually pulled the CZ from the railroads that participated:
CB&Q pulled the CZ from Chicago to Denver:
-Silver passenger F3ABA set starting in 1949 thru early 1950’s, then E7’s and E8’s mainly after that thru the end in 1970.
D&RGW pulled the CZ from Denver to Salt Lace City:
-Alco PA/PB/PA sets from 1949-1958 (painted black with yellow stripes until 1952, yellow/silver with four stripes from 1952 onward).
-EMD F3ABBA painted black and silver started pulling the CZ as early as 1950, repainted in yellow/silver 4 stripe around 1952.
During the 52-58 time frame both EMD F3’s and Alco PA’s pulled the CZ. After 1958 it was all EMD F3’s. The F3’s were repainted in single stripe around April/May 1961. By the end of 1965, the F3’s were retired.
During 1966-1970 F9’s and F7’s pulled the CZ, usully from the following number sets:
-F9ABBA #5771,5772,5773,5774, F7A’s #5761, 5764, 5471, 5574, 5551, and of course F9B’s 5762, 5763. F9A #5774 was wrecked by fall 1958.
Western Pacific:
F3ABB sets pulled the CZ at first but by 1951 or so, WP purchased FP7A’s and F7B’s to suppliment, and after that it was primarily FP7A’s which led the WP power consists followed by two B units made up from F7B’s and F3B’s.
Athearn Genesis has produced Genesis F9AB and ABB sets in single stripe which is good for late 60’s.as well as F3ABBA sets in 4 stripe and single stripe, and black/yellow stripe.
Proto 2000 has produced F3ABBA sets in single stripe but are a bit less accurate but very close.
Proto 2000 has produced PABA sets in yellow/silver four stripe but are hard to find.
BLI/MTH has produced PA’s in silver, black/yellow, and yellow/silver 4 stripe (just out recently).
Proto 2000 has made silver CB&Q E8’s and F3’s also I believe.
Genesis just produced last year accurate FP7A/F3B or FPA/F7B sets, as well as
