摘要：	This study focused on the deployment of wireless technologies to advance railroad operations. As such, there are five key phrases that collectively capture the essence of this study. 1. Levels of Operability. Wireless technologies can provide an unprecedented level of timeliness of data as to the status of remote and mobile resources both within the boundaries of an individual railroad as well as across the industry. This micro and macro perspective, respectively, presents the challenge of operability (usability) in deploying wireless-based infrastructures that overlay, complement, or replace traditional operational-critical infrastructures, e.g., voice radio, traffic control, Automatic Equipment Identification (AEI), Electronic Data Interchange (EDI), and telephone. There are six levels of operability: Railroad Intraoperability: the ability of a railroad to use its operating resources across its own network. This presents the classic challenge of how to manage unequipped units. In the case of locomotives, up to 20 percent of the fleet being used can belong to other railroads, thereby resulting in a tradeoff between reduced functionality and increased operating costs to equip foreign locomotives. Interoperability: the challenge of the interchange of trains between railroads again presents the tradeoff between reduced functionality and increased operating costs relative to unequipped units entering the operating railroads network. Industry Intraoperability: the value of having access to a railroads resources when on another railroad. This area has been little explored due to the lack of effective access to each railroads data by other railroads, as well as the lack of an industry-based tracking system. Train Intraoperability: a developing level of operability as to the environment within and surrounding the train. This is an area that has recently received some attention due to some Association of American Railroads (AAR)-sponsored activities in addition to the pursuit of Electronic Control Pneumatic (ECP) brakes.
