CN 324 is leaving Cantic on the Swanton Sub, on its way to St. Albans, Vermont. Closer to me, AMTK 68 is stopped on the Rouses Point Sub. Normally 68 would continue south on this line to reach Rouses Point, but because CN 529 is coming north, 68 will have to back up and go onto the Swanton sub temporarily to let CN 529 pass before going back on the Rouses Point Sub.
