Joint Bars

Nortrak-Damy supplies both new and used joint bars to fit standard rail sections. Bars are punched with off-round holes to accept diamond or oval neck bolts which prevent the bolt from turning while nuts are being tightened.

The term joint bar refers only to one type of connector bar and frequently is confused with other types. There are three basic types of connector bars; splice, angle and joint bars.

In addition to supplying joint bars to join rail ends together and hold them accurately in position, Nortrak-Damy supplies Compromise and Insulated Joints. Compromise Joints are specifically designed bars to connect rails of different sizes or drilling patterns. These bars are designed to smoothly match the gage-head face of two rails. These bars are usually sold in sets, consisting of four different bars. Bars are identified by standing in the centre of the track between the "heavy" or high rails facing direction of the "light" rails, indicate the joint to the right as the "right hand" joint and the joint to the left as the "left hand" joint. The four bars are: Left Out, Left gage, Right gage and Right Out.

To order please specify:

  • Section of two rails to be joined.
  • Number of holes in each rail end, hole spacing and height.
  • Size and shape of holes in bar.
  • Number of sets required.

Insulated Joints are installed in place of regular joint bars to prevent the flow of electrical current in a track circuit from passing from one rail to the other or through switches and other track structures. There are three basic types of insulated joints each suited to a particular application.

Continuous Joints are easily installed and least expensive. They require good track support and maintenance to provide a long life and are commonly used with jointed rail.

Epoxy Joints are easily installed and require less maintenance than continuous joints. They are available in standard and heavy duty.

Bonded Joints are epoxy bonded to rail making an inert joint. They require extensive field preparation including physical and chemical cleaning of the rail ends before installation of the bars. When installed properly, the joint is permanent. The care required for detailed installation can be overcome by Installing plugs. Plugs have bonded joints installed in rails from 10 feet to 39 feet long and are thermite welded or bolted into track.
