Describes a rail joint in which the fishplates are clamped to the rails by means of bolts through the fishbolt holes furthest from each rail end.
Continuous Welded Rail (CWR)
Rails welded together to form a continuous length greater than a nominal 36m in length.
Emergency Bridging Pieces
Inverted channel sections used to bridge a large gap (up to 165mm (6½″)) between 2 rail ends in an emergency.
Fly-Fished
The joining of two rails by means of a pair of fishplates which are fixed to one rail only.
Insulated Joint
The connection of two rails by means of fishplates which are insulated from the rail steel and bolts by a non-conducting medium.
Ordinary or Expansion Joint
Non-insulated connection of two rails by means of fishplates and bolts, designed to accommodate longitudinal thermal expansion of the rails.
Temporary Rail Clamping System
Specially forged fishplates held together with clamps which can be applied to a rail at a defect (or some breaks) to hold the rails to line and level.
Tight Joint
Non-insulated connection of two rails by means of fishplates and bolts but without an expansion gap between the rail ends.
Welded Joint
- Flash Weld: Weld between abutting rail ends made by the electric Flash Welding process.
- Alumino-thermic Weld: Weld between abutting rail ends made by the Aluminothermic Welding process.
