Spent about 7 hours in the great hotspot of Princeton Jct., NJ. Saw plenty of Acela’s flying past close to 150mph, 125mph Regionals, and the Dinky to Princeton with the classic Arrow III MU’s with their wistful, sentimental, and nostalgic Westinghouse AA2 horns. We also see some Amtrak diesels with fascinating histories. The Dinky is for the durable as you will see.
