Radio Subsystem Overview: SMART’s existing radio communication system is primarily used by train dispatchers, train operators/engineers, code compliance officers, maintenance-of-way (MOW) personnel, rail yard personnel, vehicle maintenance (VM) personnel and supervisory personnel for daily operations, dispatching of both passenger and freight trains, and maintenance activities for the SMART system. In addition, the current communication system allows dispatchers to communicate with marine traffic at the Haystack Bridge located in Petaluma, CA over a Coast Guard voice channel. The existing physical radio subsystem includes the following elements or devices: • (3) Dispatch / Workstations • (5) Back-up Radios at Dispatch Location / Stationary Mobile Radios • (46) Repeaters / including all necessary ancillary equipment • (43) Mobile Radios installed in non-revenue vehicles • (18) Mobile Radios installed in revenue vehicles • (136) Handheld radios, including accessories • (1) Bidirectional Amplifier at the Puerto Suello Tunnel located in San Rafael, CA. • (1) Mobile Radio at Haystack Bridge used for communication with the Coast Guard channel. This radio is remotely operated by Dispatchers from the Rail Operations Center (ROC) located in Santa Rosa, CA. B. Description of Existing Operation Mobile and portable radio units talk between each other through twoway radio repeater equipment (“Mobile Relay”), located at a high location, or situated along the right-of-way, if required, for fill-in. This communication uses Radio Frequency (“RF”) as the transmission medium. This RF conversation will also be received by the repeater unit and transmitted to the Dispatch Center located at SMART’s Rail Operation Center in Santa Rosa, CA via local area network (“LAN”) or wide area network (“WAN”), or the SMART Communication Transport System (“CTS”). If a network system failure occurs, the RF signal will be transported to the Dispatch Center through direct RF being received by the back-up radio equipment located in the Rail Operation Center. There will be one back-up radio in place for each talk group necessary for day-to-day activities. Current voice communications are recorded via a JEI Digital voice recording system.
