Car Stops and Bumping Posts for Freight Cars

We have three levels of car stopping products based on frequency of use and the length of the train that will make contact with the stop.
Car stops are sold in single units but should always be used in pairs.


Car Stop Usage
End-of- Track Stop
For car storage tracks and lightly used loading tracks.
Car Separation
Avoid contact between rail car being moved and nearby parked rail cars. Provide ample distance between stops and car.
Backup for Chocks
Provide additional stopping protection if wheel chocks/brake can't hold car steady.
Chocking on Grades 1% max.slope:
  1. Install one stop on each rail.
  2. Ease car up against stops - no impact.
  3. Apply brake and chock rear wheels
  4. For multiple cars use multiple pairs of stops (1 pair per car).
  5. Provide adequate means to stop car movement when car stops are removed.

Rail Skids
Rail Skids
Cast-steel rail skids (or "skates") can be used as wheel chocks or as car-stopping devices for slowly moving freight cars. 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 yards away from the other. Let car roll forward at 3 to 4 mph 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.
Replace skids when tongues become deformed.
Skid tongue must lie dead flat on the rail to be effective.
