When I was a kid, growing up in the 60s and 70s near Trenton, NJ, I used to ride the train to NYC all the time. I can remember vividly the engine approaching the station and the Mars light flashing, which thrilled me.
I have been trying my best to find an o gauge train that could duplicate that experience for a while now, but I guess I first need to figure out what engine would have been pulling passenger cars in the Northeast Corridor, passing through Trenton, and sporting a Mars light.
Any ideas?
