Calif. High-Speed Rail Authority acquires radio spectrum for train communications
The agreement with Access 700 LLC, a subsidiary of Access Spectrum LLC, for 44 frequencies covering the lower section of the state, is critical for the development of secure and reliable train communication systems, such as PTC.
The California High-Speed Rail Authority (Authority) received final approval to acquire exclusive rights to the radio spectrum needed to operate future communications systems for its trains.
The agreement with Access 700 LLC, a subsidiary of Access Spectrum LLC, for 44 frequencies covering the lower section of the state, is critical for the development of secure and reliable train communication systems. These systems include features like Positive Train Control (PTC) and the ability to monitor train conditions and diagnostics, as well as operate security systems along the high-speed rail system.
Radio spectrum is divided into bands of frequencies that have different properties and characteristics. The Authority purchased Access Spectrum’s Upper 700 MHz A Block spectrum because the signal is clear, not susceptible to interference and not shared with other users. As only authorized parties will have access to these frequencies, they are ideal for secure communication between trains, Authority facilities and public safety agencies.
“By obtaining exclusive rights to this spectrum, we will be able to ensure a secure communications network for future high-speed rail operations across California,” said Authority Chief Program Manager Frank Vacca.
The Authority’s board of directors in February approved the agreement to purchase the 44 frequencies at $0.70/MHz-pop (2015). The agreement received final approval from the Federal Communications Commission this month. The Authority has also entered into an agreement to purchase radio spectrum rights (43 frequencies) in the upper geographic area of the state from BPC Spectrum LLC.
On a recent episode of METROspectives, METRO Magazine’s Executive Editor Alex Roman sat down with Ana-Maria Tomlinson, Director of Strategic & Cross-Sector Programs at the CSA Group, to explore a bold initiative aimed at addressing those challenges: the development of a National Code for Transit and Passenger Rail Systems in Canada.
During a safety blitz, Metra employees will visit one of the railroad’s 243 stations during the morning rush hour, distributing educational materials on train and grade-crossing safety, answering questions, and listening to riders’ safety concerns.
Operated in partnership with Tech Valley Security, trained CDTA Ambassadors will be on select routes and will rotate throughout CDTA’s route network. Their presence is intended to provide customers with an approachable, visible resource focused on assistance and engagement.
Customers have always been able to report concerns through the CATS Customer Service line or the “Report a Problem to CATS” feature in the CATS-Pass mobile app; however, CATS has also integrated a Text-a-Tip line, giving riders multiple, easy-to-use channels to get support.
The audit found multiple safety compliance failures at the Charlotte agency, citing elevated assault risks and ordering corrective action within 30 days.
While their comprehensive analysis of bus stops focused on Massachusetts, the researchers are excited about the generalizability of the findings and application to other locations.
The new filters include substantially more activated carbon than traditional HVAC filters, which is especially helpful in providing a better transit riding experience for vulnerable populations, particularly children, seniors, and people with chronic illnesses, according to the CTA.
