That's interesting to hear, jimnorthwood, about your uncle's warehouse. So it's nothing new for railroads abruptly pulling out switches when the cost isn't justified. Tonight I'll probably post another couple of aerial shots, including of the C&O north of Davision Rd. Many spurs on that stretch. I think I-475 downtown opened in 1981. For many years it was unfinished between Court St. and N. Saginaw St. The wretched condition of the Stevenson St. crossing reminds me of the CSX Carpenter Rd. crossing. It was always horrible, don't know how it is now. After GTW severed its old main downtown, it pulled back to the west riverbank. By the mid-1980s it had cut back to Grand Traverse St., and that remained in use until the end of Delphi West service.
I certainly wish I knew what the occasional group of hopper cars west of the N. Kearsley diamond was for. Sometimes they were parked just east of it, too. The CSX line was built in 1922. As the junior road, maybe it was responsible for diamond maintenance and that's why GTW was in no hurry to remove it. I have no idea. I don't even know if after removing Franklin to Dort circa 1988, GTW ever again used the NW quadrant wye to serve AC. But, that had to have been the only reason the diamond was kept. The switch to James Lumber was torn out when the line was cut back to the west side of Dort.
