The Federal Railroad Administration (FRA) sponsored a project, performed by the Transportation Technology Center, Inc. (TTCI), to investigate next generation track circuit concepts that could support future methods of train control. Future train control concepts are being investigated in which train separation will be controlled by alternative technology (e.g., Communications-Based Train Control) while broken rail and roll-out protection are to be independently provided by track circuits. TTCI developed a Concept of Operations (CONOPS) document, conducted a technology survey, issued a Request for Information (RFI), and researched the characteristics of rail as a sensing medium.
Positive train control (PTC) offers the promise of significant potential benefits in railroad safety, capacity, and efficiency. However, PTC reveals n...
The objectives of this project were: • Assessing compatibility and determining how the proposed VBTC concept could be integrated with and enhance th...
