While I was in college, I made frequent trips to visit my cousins in Maryland. If I couldn’t secure the use of one of my parents’ cars, I would take the rails, and I would make a day of the journey. Starting in Bethlehem, I would ride the RDC’s on Conrail’s former Reading service to Reading Terminal in Philadelphia, and then take the subway from there to 30th Street Station for an Amtrak NEC train to Washington. I arrived in DC with a few hours to kill before I could board a B&O commuter train to Brunswick. During the wait, I would walk the platforms for photos, and I also discovered that I could enter the Metro line and ride back and forth between Union Station and Rhode Island Avenue while shooting the passenger activity at Union Station. Here a shot from the Metro train shows two Washington Terminal RS1s working while a B&O torpedo boat GP9 waits to take a commuter train west. One of the interesting aspects of this photo is the B&O passenger consist behind the GP9.
