This album features year four of Conrail operations.
The year saw Alcoís fade from mainline service at Morrisville, Bethlehem, and Enola, although Alco RS-11ís were still operating at Bethlehem in July, 1979.
At Croxton in August, 1979, Alco RS-3Mís were operational along with some ancient SW-1ís.
After over 40 years of service, GG-1ís were still going strong in June of 1979. An August funeral train of E-44ís and E-33ís at Morrisville, however, signaled the nearing end for all electric power on Conrail. GG-1's and E-33's led mainline freights in late November, 1979, but by the spring of 1980, only E-44ís were seen operating out of Morrisville and Enola.
