Remarks: After paying my respects to Horseshoe Curve when I arrived in town for Railfest '09, I relocated to Cresson and set up just outside the pedestrian underpass to take in the afternoon's action. An eastbound stack train led by a pair of C40-9Ws paused for a while at the signals before making a VERY slow exit out of town (the unedited clip is over 11 minutes long). As the tail end approached, two more C40-9Ws led by the 9466 headed west with a mix of intermodal traffic.
