The Early Bird Gets the Adirondack: MARC II Cab Car #7753 leads Train 69, the Adirondack, towards Metro-North's Harlem-125th Street Station early on Saturday morning, June 2, 2018, as a bird flies in the distance. Notably, a P32AC-DM is sandwiched between the MARC Cab Car and the Amfleet consist. With ongoing work on Amtrak's Empire Connection, its Empire Corridor trains are running to/from Grand Central for the summer.
