  • Began with Conrail/MDOT/AMTRAK to speed up passenger trains across Mich.
  • Initial development in mid 1990’s – still being upgraded to original 110 mph target
  • Includes advanced crossing start for high speed trains.
  • Was Harmon system based on VHLC and UltraCab Cab Signal designs.
  • Uses distributed “zones” of control which communicate peer-to-peer with vital data

  • SUPPLIER(s): Harmon then GETS-GS
  • STRUCTURE: OSI 7-layer GE proprietary layers 2, 3, 5, 7 TCP/IPInternet protocol and TDMATime Division Multiple Access
  • MESSAGING STD: Proprietary application over IPInternet protocol
  • FREQ BAND: 220 MHzMegaHertz (MHz) 10^6 Hz
  • RADIO MFGR: GE MDS spread spectrum radio
  • COMMS RANGE: Dependent on Wayside Zone design and train speed limits
  • COMMS BETWEEN: Wayside zone and locomotive, Wayside-wayside (proprietary msg)
  • STATUS: In service – being expanded(as of 2012), currently approved for 110 mph operation
