The Federal Railroad Administration (FRA) maintains a National Crossing Inventory and the Railroad Accident/Incident reporting System. Reporting is accomplished by information received from Railroads and states agencies, such as TDOT’s Highway Grade Crossing Unit who oversees Tennessee’s crossing inventory data.
TDOT receives monies each year for the crossing improvements from the Federal Government under MAP 21, Federal Highway. These improvements can range from Railroad Warning Signs, or Pavement Markings and Signals, Lights, and or Gates. Section 130 staff also reviews and makes recommendations on highway improvements near railroad crossings.
After the crossing selection process is completed a Diagnostic Team Review (DTR) is conducted by the Grade Crossing unit personnel. TDOT Engineers recommend and choose the safety upgrades. A crossing project from start to finish takes approximately 1 (one) year.
The Railroad performs the work of installation and maintenance at each location, TDOT staff is responsible to assure the standards of the MUTCD and other federal regulations are met. TDOT is also responsible for the design, construction, and maintenance of the roadway approaches outside of the 10 foot from rail (TCA Law).
The railroad crossing inventory includes the data required to be maintained by the Federal Railroad Administration (FRA). The annual list prioritizing crossings for safety improvements was created from a Rail-Highway Crossing Resource Allocation Procedure using railroad crossing inventory data and crash data is obtained from the FRA. Safety Improvements are determined for each crossing project as listed below:
