I became a train geek in the Philadelphia area between 1964 and 1970. For me, the GG1 was what I first thought when I heard the word "locomotive.", Everything else was EMUs, either the PRR MP-54s or early Silverliners, and whatever it was that the Reading used. I think when I was 11, I rode an RDC on the Pennsylvania-Reading Seashore Lines from 30th St. to Atlantic City. It might have been the first diesel train I ever rode, and that was a DMU. I'd see the pictures of the diesel streamliners in train magazines and thought of them as exotica. When I was 14, I got to ride the Denver Zephyr behind some sort of diesel power, and when I was in high school, I took the occasional joyride to Norristown on something called the "King Coal Express" a Reading train tp Pottsville that used an F unit diesel (which I think is now on display in the parking lot at Steamtown in Scranton.) Oh, and for three years I went to a camp in Mass. that involved a trip on the "camp train" from Grand Central up the Housatonic, which I think was electric to Danbury and diesel after that. But I rode up to New York behind a GG-1.
