First night with my remote shutter release, and I loved it! A CN transfer for Stinson Yard heads south. Once they reached the diamond, the trouble would start. The could not get the signal to drop for them, and in the course of 45 minutes, they had consulted each other, the Soo Line and CN rulebooks, GCOR, two different RTC's, a BNSF crew, and finally they received permission across.
