Caption: A trio of ECO units proceeds west slowly through Peterborough crossing Aylmer Street. When I was a Kid growing up here this train ran at night. Back then the power was usually a mix of four axle power, GP-35's C424's or RS-18's. One time a C&O GP-30 showed up. Back then my brother was the camera guy and film was expensive. As teenagers there were other pursuits, so there aren't any photos from those days.
