I visited some weeks ago the Hoosier Valley museum to see the NKP765. In the materials I found for the history of this locomotive I found this information:

The Silent Watchman, a special feature that recognized when the pony wheels derailed, still worked after sixteen years of disuse!


Does anybody knows what this feature exactly was? Thank you very much.
