This is an Atlas Gold Series (DCC & Sound from QSI) model. This came decorated as Reading 2772. The model was intentionally bought so it could be patched into Conrail. Based on roster notes available online through the Conrail Cyclopedia (crcyc.railfan.net) I literally patched this unit into its Conrail number. RDG 2772 became CR 9622. The most fun I had was actually patching the black diamond logo on the side. With a little bit of math and geometry it was easily done, and the yellow border still remains. After scale couplers, and some liberal weathering using various shades of black, the unit is done.
