Radio communications-based train control (CBTC) systems, also referred to as transmission-based signalling (TBS) systems, permit more effective utilization of rail transit infrastructure by allowing trains to operate safety at much closer headways, by permitting greater flexibility and greater precision in train control, and by providing continuous safe train separation assurance and overspeed protection. One of the challenges facing transit agencies who are considering the introduction of CBTC systems, however, is the lack of industry standards for this emerging technology, and the current inability of trains equipped with CBTC equipment from one supplier to operate on track equipped with CBTC equipment from a second supplier. This paper reports on the status of two separate initiatives being taken in North America to develop standards for CBTC systems for rail transit applications; one based on a voluntary consensus development approach, and the second based on a competitive procurement approach.
