NS 1065, Norfolk Southern's Savannah & Atlanta Heritage Unit, leads an Austell, GA to San Bernardino, CA Z7 train out of Crozier Canyon on a chilly autumn morning in Arizona's high desert, Oct. 28, 2020. With PTC being compatible between the host railroad and foreign railroads, these NS interchange trains have been running through the interchange point without swapping the power to BNSF motors. This is the third day in a row a NS interchange train has passed over the subdivision with an NS leader.
