| | ===== RailCom ====== |
| | |
| | |
| | A relatively new DCC standard to implement return messages from a train/decoder. It was originally developed by Lenz, and is now a NMRA standard. Further development is in progress by European companies, and this extension is called RailComPlus. |
| | |
| | RailCom works by having the command-station/booster stop driving the rails between DCC packets, during the inter-message idle packets, and then the decoder generates a 20 mA serial encoded signal. This is decoded by the command-station and/or other RailCom decoder(s). |
| | |
| | RailCom/Plus allows: the identification of unknown trains; block occupancy; transmission of train information, such as its actual speed; and more efficient 'on-the-main' programming. See: [[http://www.nmra.org/sites/default/files/s-9.3.2_2012_12_10.pdf|NMRA standard]] and [[http://www.esu.eu/en/support/white-papers/railcomplusr/|ESU RailCom Plus]]. |
