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 a stopped car.
- Slowly roll the car forward so wheels can mount skids.
- Apply car brakes. Chock other ends of the car on a flat track.
- As a Car-Stopper (for flat track only): Place skids on each rail, one skid a few meters 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 a 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.
