Incremental Train Control System (ITCS)
From Signal Identification Wiki
- 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
- SPONSOR: GE/MDOT/AMTRAK/FRA (CONRAIL - NS)
- 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
