Catch Points - Sand Drag

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.
