Analysis of Non-Track-Circuit Highway-Rail Grade Crossing Train Detection Technologies
This research investigated the suitability of non-track-circuit-based technologies as a cost-effective means to deploy active warning devices at passive grade crossings. While several promising technologies were identified, some of the findings were unexpected. Mainly, there existed...
Wheel Bearing Brake/Instrumented Wheelset (WBB/IWS) Friction Characterization Study
The wheel/rail (W/R) interface experiences variable friction conditions during in-service operation. This is due mainly to the application of top-of-rail friction modifiers (TOR FM) and gage face (GF) lubricants, and other third-body materials that exist at the W/R interface due to non-...Development of Enhanced Overlay Positive Train Control (EO-PTC)
Transportation Technology Center, Inc. (TTCI) researched a new method of train control proposed to increase operational efficiency where Positive Train Control (PTC) equipment is installed and operational. Enhanced Overlay Positive Train Control (EO-PTC) allows for the removal of signal-based...FY19 Federal-State Partnership for State of Good Repair Grants NOFO Webinar
