Amplified with 174 additional chair car seats (provided by a pair of 52-seat cars and one-of-a-kind 70 seater SILVER LEAF, thb latter built for the General Pershing Zephyr), No. 1 (the Denver Zephyr) gets out of Chicago behind E5s SILVER SPEED and SILVER POWER on August 21, 1949. Passengers aboard the amplified portion of the Colorado-bound Zephyr will drink and dine aboard 36-seat diner SILVER SPOON riding first-out behind the E5B. Meanwhile, Gulf Mobile & Ohio Alco S2 No. 11 gathers head-end cars for spotting at the mail terminal (they'll go south tonight on the Advance Midnight Special to Saint Louis) as a GM&O E7 (visible immediately above SILVER SPOON's rooftop kitchen vents) awaits its next call to duty in GM&O's tiny Harrison St. yard. Photographer Jim Scribbins recorded the action from the Polk St. overpass."/>
