Special Specifications

If track work is involved, special specifications will usually need to be added to the PS&E. Examples include:
  • Ballasted track construction.
  • Underpass structure.
  • Culverts or drainage pipes under track.
  • Contractor prequalification for trackwork.
Any pipes underneath the track must meet Cooper E-80 loading requirements.
Designers should pay close attention to any track specifications to confirm the specification correctly identifies if a contractor is:
  • Providing track materials.
  • Performing track removal.
  • Salvaging track materials.
  • Building track panels.
  • Performing track installation.
  • Performing track tie-ins.
RRD
and the Bridge Division can assist the districts if special specifications are needed.
The following items do not usually require special specifications since they are provided by the railroad company:
  • Crossing surface panels.
  • Active warning devices (i.e., gates, cantilevers, and mast flashers).
  • Passive warning devices (i.e., crossbuck signs).
