Prohibits the operation of N.Y. city transit authority subways or trains without a conductor on board

This bill requires at least one conductor to be present on all New York City subway and train cars operated by the transit authority, with limited exceptions for situations where it is currently allowed. The legislation defines a conductor as any staff member other than the driver or engineer who is primarily responsible for train operations, door management, and safety duties. Proponents argue that conductors serve as first responders during emergencies and enhance security following the September 11 attacks and recent threats to the transit system. The law takes effect immediately upon passage and applies to all passenger-carrying trains within the authority's jurisdiction.
