Three railroads operated in the Reading-Allentown-Bethlehem corridor in eastern Pennsyvania- the Reading, Lehigh Valley and Central New Jersey. In the mid seventies, all were absorbed into the new Conrail. When Conrail was split between NS and CSX, these lines were conveyed to NS. This program covers Reading Yard, Macungie, Emmaus, Allentown Yard and Bethlehem, including CP Burn, the hump, Lehigh River and Lehigh Canal bridges and the Lehigh Valley bridge to Bethlehem, as well as the old Bethlehem Steel Mill. 2 hours- Map- Narration
