In some cases, catch points and trap points direct vehicles into a sand drag or safety siding, also sometimes called an arrestor bed. This may be a siding simply leading to a mound of sand, gravel or other granular material, or a siding where the rails are within sand-filled troughs. This method of stopping a vehicle travelling at speed is preferred over a buffer stop as there is less shock to the vehicle involved.

Famous quotes containing the words sand and/or drag:
“But the twelve lie in the sand by the dry rock
Seeing nothing—the sand, the tree, rocks
Without number—and turn away the face
To the mind’s briefer and more desert place.”

“Error is acceptable as long as we are young; but one must not drag it along into old age.”
