Stranger in a foreign land. Thanks to the busiest travel day of the year, the Sunday after Thanksgiving, Northeast railfans are treated to unusual sights with Amtrak leasing commuter rail equipment to handle the extra load. One of Amtrak's northbound holiday extras, made up of a MARC HHP-8 and 6 cars, crosses the Delaware River from Morrisville, Pa. into Trenton, N.J. Note the famous "Trenton Makes - The World Takes" bridge in the background.
