  "term": "Edge rail",
  "field": "Industrial and trades",
  "definition": "An early form of railway track where the wheels of the rolling stock ran on the top edge of a raised rail, rather than within a flanged plateway. This design allowed for the development of flanged wheels, which provided better guidance and reduced friction. Edge rails became the standard for modern railways.",
