AEI (Car Tag Reader) & Posi-Stop

[elENblef]

Need a simple car tag reader that will operate switches matching cars having matching tags / AI-Tags. Also either a bumpstop setup as Posi-Stop, &, or a small section of track setup as Posi-Stop, a sign something, so that loose cars having been kicked be it manual, loco-attached, even a hump bowl haven been setup. With Posi-Stop will prevent car(s) rolling past it, & with each car rolling against the one ahead of it won't allow car(s) to be shoved further past the Posi-Stop like they do now, no matter what's put down as a stop, stop & hold you name it.. Right now, only way to prevent cars rolling further once they reach one end is to place an engine, let cars roll against it.
