Cameras are now a necessity in buses, commuter trains, streetcars and subways as demonstrated by the New Jersey commuter train accident. Managing companies are not only recording video, but keeping it longer and installing the equivalent of an airline black box. The company that operates The Cincinnati Bell Connector, Transdev, says it has installed SmartDrive cameras. "Within a week of deployment we clearly saw the benefit of video safety for rail," said Ken Westbrook, president, Transdev Rail.
