The history of railroading in Pennsylvania is quite interesting, especially since so many lines are still in use. This clip of the Erie Lackawanna is on tracks which are now operated by the North Shore Railroad.

Two Penn Central trains at Congers, NY which is near the New Jersey border. Big Mike calls these eastbounds, but the line is a north-south route, so they are actually heading directional south. The station at the left of the going away shots is now a restaurant (The Station Kitchen and Bar) and gives today's railfan a chance to dine outdoors and watch CSX trains!
