In Volume 4 of Railfanning With the Bednars, we railfan April 1973 to early June 1975 and the arrival of the GE U23Bs on the Valley. The U23Bs would be the last new locomotives the Valley would receive.

Locations include Bethlehem, Allentown, Catasauqua, Hokendauqua and other points west to Sayre. West of Sayre, we visit Cayuta and Lockwood, NY. The Bednar gang also makes a visit to western PA to capture the Penn Central at Horse Shoe Curve and other well known railfanning locations on the PC.
