CP train 252-20 heads South through the ex. PRR Buttonwood Yard complex located in Buttonwood, PA (M.P. 692) along the CP Sunbury Sub with NS 8023 and NS 9006 for power on the afternoon of January 20, 2013. Today very little remains of the once sprawling yard complex, with only the mainline, an interchange spur with shortline L&S and a 1500' industry spur with a scrap and salt dealer being serviced by CP.
