Blockline, Conrail operated trains on the Delaware (Erie) and Pocono (DL&W) Divisions at first. I lived in/near Elmira in the late '70s and operations looked very similar to EL- for a few years. The auto racks, pigs and merch trains all ran at frequent intervals. Plus the line west of Waverly was handling the Apollos, since D&H had taken that service over from LV. CR also routed up to 3 daily trains in each direction between Allentown and Buffalo- LV to Waverly then EL to Buffalo. So at the time, I thought Conrail was a good thing (despite the loss of LV) because the Tier was busier than ever, and the explosion of color was very cool.
In 1979, Conrail downgraded most of the Pocono Division and shifted the remaining traffic to the Delaware Division. The ex-DL&W between Bingo and Scranton was sold to D&H the following year, with the remants in Scranton being sold a few years later. Around the same time, CR also began routing trains off EL altogether via either the West Shore or ex-PRR lines. So that basically ended big freight runs on the Pocono Division.
Hopes this helps...
