Railcar Wheel Chocks


Single Chock	Single Chock with Red/White Flag

Double Chock	Double Chock with Red/White Flag


Exposed Rail	Paved Rail

Chock the wheels on stationary railcars to keep them from moving during loading, unloading, and servicing. They’re for chocking railcars on a flat track, so they’re not recommended for use on tracks at an incline or decline. Chocks install quickly, without tools.

Single Chock—Single chocks prevent forward motion.

Double Chock—Double chocks prevent forward and backward motion.

Railcar Wheel Chocks with Red/White Flag—A flag indicates that chocks are in use.

Painted Steel—Painted steel chocks are connected by a chain; a rubber strap attaches to the chain and draws the chocks together.

Polyurethane Plastic—Polyurethane chocks won't degrade from corrosive chemicals, unlike steel chocks. They’re compressible, so they can expand back to their original shape. As a result, these chocks will not cause a spark or damage to the rail if a railcar runs them over. When you’re ready to remove them, pull the railcar over them before retrieving. They're connected by a cable, which weighs less than a chain and won't corrode from moisture.

Magnetic Railcar Wheel Chocks

To firmly hold railcar wheels in place, these chocks have magnets on the back for extra grip on rail tracks. Use them to keep railcar wheels stationary during loading, unloading, and servicing.

Railcar Wheel Stops


Foldable Wheel Stop Shown on Rail	Wheel Stop Shown on Rail (Sold in Pairs)

Stop moving railcars at track ends and as they approach buildings and doors.

Foldable—Foldable wheel stops swing down to the outside of the rail when not in use. You’ll need a left and right stop for a complete pair. They come with a padlock to keep them in the upright or lowered position, preventing unauthorized use. Bolt these stops onto your rail after drilling four 1 _1/16″ holes into the rail web.

Not Foldable—Nonfoldable wheel stops clamp to a rail, so no drilling is required for installation.

Railcar Stoppers

Bring slow-moving railcars to a halt. These stoppers have a chock at the end of a handle that you can place and remove in front of a wheel several times to absorb its momentum. They can hold a wheel in place until you install a permanent chock. After you’ve positioned a car with a railcar mover, they’re great for stopping it at an exact location. Use them to guide railcars to scale checks, repair shops, and loading zones. These stoppers are for use on flat track only.
