  17. Immediate System Improvements The RAIL system, Locus CCRS & Communications Equipment provides numerous benefits: • Replaces antiquated command & control equipment with • state-of-the-art, highly reliable, fault tolerant equipment. • Improves the local interface with the Loran Station. • Improves remote Command and Control to LCCS. • Improves archiving functions and integrity of data. • Improves reliability and availability of the Loran signal.

  18. Future Plans The RAIL system, along with the Communications Equipment will provide the interface to two systems in development: • Timing and Frequency Equipment (TFE) • Transmitter Control System (TCS) for the new SSX Transmitter • Graphical User Interface for TFE . • Graphical User Interface for the new TCS. • Local and Remote Electronic Interface for TFE. • Local and Remote Electronic Interface for TCS.
