Aldon 4016 Series Rail Skids

Aldon 4016 Series Rail Skids

Cast-steel rail skids (or “skates”) can be used as wheel chocks or as car-stopping devices for slowly moving freight cars. Replace skids when tongues become deformed. Skid tongue must lie dead flat on the rail to be effective.

  • Skids are also a low-profile chock for idling locomotives.
  • As a Wheel Chock (for flat track only): Place skid on each rail a few feet in front of stopped car.
    • Slowly roll car forward so wheels can mount skids.
    • Apply car brakes. Chock other end of car on flat track.
  • As a Car-Stopper (for flat track only): Place skids on each rail, one skid a few metres away from the other.
    • Let car roll forward at 5-8km/hr maximum speed.
    • Wheels will mount skids and resulting friction of skid under wheel load brings car to a gradual stop.
  • Note that a skid can be knocked off rail; be sure to have a derail installed further down the track, just in case.
