100% SAND DRAGStop And Not Derail Delinquent Railcars... A Godsend! Angela Brett (according to http://www.glue-it.com/trains/general-information/glossary/glossary/frames.htm a Sand Drag is a short length of railway track buried in sand, and running from a set of catch points. It is designed to bring runaway vehicles to a halt rather than derailing them.)
