No, not THAT kind of sign...
I need to own, or I need to borrow, so I can copy, a NYC TA safety sign that says "Read the Iron."
If anyone can lead me to a link, that would be great, too.
The sign was posted at yards and other places on the system to warn track workers to be aware of how the turnouts were set, so that they could tell how movements would be switched.
I seem to recall that the sign had a drawing of track work, showing turnouts.
