I wasn't even born 80 years ago. But as a 6 year old, I can remember eating lunch with my uncle at his Great Northern freight station new the New Haven yard in New London, CT. While we ate we could watch early ALCO switchers working the yard as I-4 Pacifics relegated to fast freight service passed, while ALCO PA's had taken over passenger service. Once or twice a week there would even be a Pennsy passenger train headed to Boston.
