The neat thing about this line was its variety.
Ferries, then busy, mulit-carrier terminal, The four track CNJ mainline was through heavy commuter territory. Then onto the Reading's Trenton line was the feeling of a mid-20th century version of the TGV. Reading's commuter territory again, and big city, bridges, and river run to Park Station. Then, all of a sudden the train was in single track territory for 60 some miles with winding curves and rural scenery. Baltimore gave great sights of freights and industry including a tunnel with two stops. From Baltimore to Washington was a fast sprint again. Into Washington Terminal the Royal Blue head her head high against the likes of Florida streamliners.
A ride in the observation car was like few other on this line. Sad thing was that though I was only 12 to 14 at the time, I worried about being the only person in that car along with attendant. I didn't keep him very busy with my hourly ginger ale (at 15 cents each).
"Passing points, New Jersey Cut-off Eastward freight trains, being handled by two engines, when clearing at Blairstown and Greendell, may hold main track and put first class or other trains through sidings."
