One of my favorite shots - Double black and blue with the east's big three RR's represented here. NS general freight 14G blows east on main track 2 by stone train 66K which is waiting by the tall signal mast at CG in Stowe Yard at Pottstown PA as a crewman from the 66K inspects 14G from the right. Trailing units from Conrail and CSX add the blue. With as little traffic as there is on the Harrisburg Line east of Reading, you'd be waiting here a looooong time before you would happen to catch this circumstance in great light:
