Some of these old style switfh targets lasted well into Conrail but I would bet they are pretty much gone today.This page... http://www.railroadsignals.us/rulebooks/nyc37/nyc37.htm has some NYC signals and switch targets on it. I can swear the diagonal metal bar and two hole bar switch target is still in use somewhere on one of the Metro-North H&H yards, probably Harmon. I recall seeing it, but can't remember where. It's either Harmon or Brewster. I know I've seen it tho.
