  • ATCS (Advanced Train Control System) - wide area messaging systems containing track signals and other train data
    • licensed to AAR nationwide, not individual railroads, though some AAR listings mention transmitter positions.
    • base sites generally co-located with other railroad transmitters, towers, or tracksides
    • there are no base sites active in the Milwaukee area, but some locomotives do send beacons in search of bases
    • ATCSmon - info from Dave Huoy
    • Some industry info from Nexterna

  • ARES Railroad Telemetry
    • Used by the BNSF railroad in northern IL and much of the US.  Data sounds like aviation's ACARS and partly syncs up using ACARS decoders. Indeed the protocol may have ties to the ARINC corp.  Thanks to David Huoy for relaying this system.  This system might is in use along the Mississippi as well.  According to the gov't, the system hasn't been implemented by BNSF, but I'm convinced otherwise!
    • Sample sound - about halfway down page

161.325 all devices - folded dipoles on short masts at each grade crossing, dual dipoles at block signals
