Authorized passenger train speed on the Northern Central was 55 m.p.h. Of course, there were speed restrictions for curvesm going through towns, etc. Dippers Curve was one of the sharpest curves on the line and had a speed restriction of 30 m.p.h., even with the curve being super-elevated like the rest of the curves on the Northern Central. Supposedly the curve got its name because in the summers when school was not in session, passengers on the passing trains could look out at the Codorus Creek which was very close to the railroad, and see kids "skinny dipping" in the creek on hot summer days.
