it was basically a barcode that reader machines beside the tracks (usually near yards) would read it off and file it in a computer, a primative predecessor to those grey rectanglar things we have today.

It's called an A.C.I. or Automated Car Identification. Like what was stated earlier it's the fore runner of todays E.C.I. tags. It wsa dropped in the 70's due to the tag geting to dirty to be read by the track side scanners.Jonathan

Today's version is the AEI tag. Automatic Equipment Identification tag. See http://www.saic.com/products/transportation/reader/ for an example.I'm having to get them on a sleeper I need moved out of New Orleans. NS will not move the car without them. Among other data, the tag is encoded with the car's reporting marks.Lee

This system was developed by GTE Sylvania and was known as "KarTrak" - there's some background at http://johnkeyes.com/archives/000202.php - You can find the KarTrak key at http://members.aol.com/Bx39crle/yard/ktkey1.htm - the numbers read from bottom to top and indicate owner name and road number.With some web searching you can find more info and appropriate codes for various equipment owners.
