Mars oscillating headlights were not popular in the Northeast. The DL&W ("Lackawanna") did have EMD E8A units equipped with Mars Lights. The Lackawanna trains terminated in New Jersey, and you would have finished your trip on a ferry.
The Pennsylvania Railroad -- while it did not normally use oscillating headlights -- did purchase a small number of passenger diesels so equipped:
- One BP20 Baldwin sharknose DR6-4-20 with a Mars Light, in 1948 and
- Two EP22 EMD E8A's with Pyle Gyralites, around 1952.
I am not certain that these orphan Pennsy locomotives retained their oscillating headlights into the 1960's, but someone on this Forum probably knows. And they were diesels, so I do not know if you were riding outside the electrified zone.
This isn't really relevant to the topic, but didn't some K4's and possibly a T1 or two have some kind of oscillating light installed as well?
