NYCT's CBTC Radio Technology Forum minutes summarize issues involving RF-CBTC by some of the world's foremost experts on this subject. Topics include key technical, commercial, and RF licensing issues and diverging paths now being taken by three leading train control suppliers, radio suppliers and consultants, and others on how best to marry RF with CBTC. Unfortunately, TSD recently received a request to remove these minutes and (reluctantly) TSD complied by removing TSD links to the original minutes and replacing these minutes with this new page containing only the agenda.
Because of its value to the train control industry we soon hope to provide a summary of these minutes. However, it may be possible to obtain a copy of the original minutes by contacting NYC Transit directly. Also, Google's search engines often retains copies of indexed documents for a limited time in its cache memory. Thus, it may be possible to locate a copy by searching Google for: "Radio Technology Forum." If a TSD web page is returned, try clicking on "Cached."
