I just realized that I had a growing backlog of news items regarding searchlight signals, some of it a little bit old, but still worth highlighting. First up the TWC/ABS territory on the end of Harvard Sub north of Harvard, WI is being replaced by CTC taking the CNW searchlight signals with them. Although not part of the METRA territory, UP appears inclined to simplify dispatching on the part of the line that probably sees only 2-4 trains per day. This is the most up to date news so anyone in the area can probably still document the old signals.
Next, the former ATSF diamond in Plainview, TX is also losing its searchlights as of November, 2020, so they might alread be gone.
Next, with the CNW ATC out of service, UP appears to feel free to now alter the interlockings on the Geneva Sub (former CNW main line) between West Chicago and Iowa, which had formerly gotten a reprieve. This will see the replacement of the CNW hallmark oval target searchlights.
Finally I have another case of some signals that got away. In early 2020, the Guilford Rail System retired the signals on the Northern Main Line between Nashua and Manchester, NH due to low traffic and the generally failing state of the system.
While the above diagram doesn't make this abandonment look that bad, there were 6 automatic signal locations and 3 interlockings north of Nashua compared to only 2 automatic locations and 2 interlockings to the south. What's even worse was that I was in the are last Labour Day, however I was fixated on the Lowell terminal area due to the MBTA's Rule 562 project and didn't even realize that the North Main Line was even signaled. I passed within 1200 feet of the retired CPN-28 without realizing it was there only to find out a few months that the signals had been taken down. Not sure what the state of the other locations are, removed or just turned, but its probably still worth checking out.
