Tie Duct Accessories

The Fastrax® tie duct is a hollow, thermally and electrically insulated structural tie capable of carrying rail loads and efficiently delivering hot or cold air to the duct system of either a switch heater or horizontal air curtain. It forms an integral part of our duct systems that can remain in place during automated tamping. So you will never need to remove cross ducts for tampers. Tie ducts not thermally insulated are also available.

Acquired from Hovey Industries Inc, our tie duct is a proven design and has been in service on Class 1 North American Railroads since 1997.

Features

  • Hollow structural tie.
  • Exceeds the AAR 3000-volt dielectric requirement for insulated track fittings, with redundant double electrical insulation.
  • Improves the switch clearing performance by delivering up to 18% more heat to the switch points. At the same time, the thermal insulation minimizes heat loss that causes soft ballast conditions and associated switch point pumping
  • For installations that require crossing a mainline track, tie ducts with the appropriate 1:40 or 1:20 cants are available with either Pandrol or Safelok rail anchors.
