Remarks: A couple of westbounds work their way past ALTO Tower, slated for demolition late this year or early next year as NS revamps the track and signals through downtown Altoona. First up is 51V, a unit grain train led by ES40DC 7565, UP C40-8 9139, and C40-9W 9510. Manifest 11K follows 6 minutes later at a more leisurely pace, with ES40DC 7503 and C40-9W 9169 leading the way.
