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:
“O that my vexation were weighed, and all my calamity laid in the balances! For then it would be heavier than the sand of the sea; therefore my words have been rash. For the arrows of the Almighty are in me; my spirit drinks their poison; the terrors of God are arrayed against me.”
—Bible: Hebrew, Job 6:2-5.
“Executives are like joggers. If you stop a jogger, he goes on running on the spot. If you drag an executive away from his business, he goes on running on the spot, pawing the ground, talking business. He never stops hurtling onwards, making decisions and executing them.”
—Jean Baudrillard (b. 1929)
