Working New York division towers in the later 1960ies, it was a pleasure to see the streamliners of the southern roads go by. Occasionally a train would be twenty two cars long, and it would have to make a second stop in Newark to platform them all.
But did you know that the GG1s pulled Metroliner MUs during the blizzard of -78
One GG1 was pulling a Metroliner when it hit a tamper at speed. No harm to the engine crew, but if had been an MU head out, it would have made the headlines.
One winter fine snow got through the screens on most of the Gs, and crippled them for a week or so. Then the southern road trains came through to Newark behind their southern diesels. The Pennsy was double heading 1/3 or 2/3 Gs to get the power of one normal engine.
That four second You Tube of the G going by, blowing its horn, excited me. Jersey passed a law years ago requiring trains to sound their horn entering stations. The Gs coming into Newark used to blow their horns loud, and I got a charge out of that.
The Southern Railway didn't join Amtrak right away, but continued running their own trains, for a time.
Electric locomotives usually run with the rear pantograph up so that if it gets ripped off, it will not damage the other pantograph.
