Abstract:

American railroads plan to complete implementation of their positive train control (PTC) systems by 2020, with the primary safety objectives of avoiding intertrain collisions/train derailments and ensuring railroad worker safety. Under published Interoperable Electronic Train Management System (I-ETMS) specifications, the onboard unit (OBU) communicates with two networks: 1) the signaling network that conveys track warrants to occupy blocks and 2) the wayside interface unit (WIU) network, a sensor network situated on tracks to gather navigational information. These include the status of the rail infrastructure (such as switches) and any operational hazards that may affect the intended train path.
