R

  • Rack Railway - A railway that can climb steep grades by using a toothed cog wheel between the driving wheels of the locomotive that meshes with the teeth of a rack rail that is mounted to the cross ties between the other rails. Also called Cog railway.
  • Radio Control - A method of operating and controlling locomotives by means of radio signals transmitted through the air or by means of a carrier control basis through the track.
  • Rail Car - Self-propelled passenger carrying vehicle.
  • Rail Joiner - A formed piece of metal that joins two rails together and helps to complete the electrical circut.
  • Rat - Slang for a freight train.
  • Razor Saw - A fine toothed saw used by model railwayers that resembles a straight razor.
  • RCS (Remote Control Section) - A type of Lionel track for unloading and uncoupling
  • Rectifier - A device for converting AC into DC.
  • Red Ball - A fast freight train.
  • Reefer - A refrigerator car. Similar to a boxcar but has ice or mechanical cooling equipment.
  • Reefer Block - A freight train consist of refrigerator cars.
  • Regional Railway - A railway which is smaller than a major railway but larger than a short line railway.
  • Resistor - A device used to reduce the intensity of electricity.
  • Restricted Track - A track section where train speeds are reduced.
  • Retarder - A device used for decreasing speed; brakes.
  • Reversing - A station where train reverses direction of travel . May be at normal dead end or terminal station.
  • Right Of Way - The land on which a railway is built; also precedence given to one train to proceed before another.
