Chicago Burlington & Quincy E-8 #9938A, Naperville, Illinois, August 21, 1964, photo by Chuck Zeiler. A spotting feature of CB&Q E-8's and E-9's was the silver painted fourth porthole. I never determined a reason for that.
Built December 1949 as CB&Q #9938A (c/n 9675), it became BN #9938. Around November 1973 it was sent to Morrison-Knudsen to be rebuilt to E-8u specs, exchanging its twin 12-567B model prime movers for 12-645EC's, and the electrical system was upgraded. In addition, the steam generators were replaced with a Cummins 500Kw generator for Head End Power (HEP). When it returned to BN rails (now numbered 9901) it was owned by the West Suburban Mass Transit District (WSMTD) and leased to the BN, and named "Village of Clarendon Hills". It worked suburban trains until July 1992 when it was retired, and eventually became Illinois Central #100.
It is shown here at the head end of westbound CB&Q Train #1, The Denver Zephyr. The DZ left Chicago's Union Station daily at 5:00PM CST, this photo was taken in August, so Daylight Saving Time would make the time of the photo about 6:30PM. The train is a half hour into its overnight run to Denver, 1034 miles, due in Denver's Union Station at 10:40AM. Running two hours ahead of this train is the daily Train #17, The California Zephyr.
The DZ's accommodations included: Reclining Seat Chair Cars (DZ-14, DZ-34, DZ-36, DZ-39), Vista-Dome Reclining Seat Chair Cars (DZ-14, DZ-35), [note; the DZ-14 was either a flat top coach or dome coach - depending on the season], Vista-Dome Buffet-Lounge Chair Car (DZ-37),Vista-Dome "Chuck Wagon" (lounge for all passengers), Dining Car, Slumbercoaches (SC-12, SC-19), Pullman Sleeping Cars (DZ-1, DZ-2, DZ-3, DZ-10), and a Vista-Dome Observation Lounge. The diner separated the coach passengers from the first class passengers. Depending on the passenger count, at least one Reclining Chair Car, one Slumbercoach, one Pullman Sleeping Car, and the Vista-Dome "Chuck Wagon", would be cut out of the DZ at Denver and attached to the D&RGW's "Royal Gorge" train and dropped off at Colorado Springs.
