CA stands for what?

Explanation:
In CBTC signaling, abbreviations are used to quickly convey train status. CA indicates a CBTC Train in Approach—a train that is approaching a point where protection or clearance is needed. This status tells the system and operators to prepare for potential route setting, speed adjustments, and to maintain safe separation as the train nears a block or interlocking. The other options refer to concepts outside of CBTC train status (such as an organizational term, a mechanical component, or an unrelated term), so they don’t fit as a status indicator.
