Terminology Edit

  • Maximum Authorised Speed: The highest speed permitted for any train on a subdivision or portion of a subdivision.
  • Normal Speed: A speed between 46 mph and 79 mph, any speed above 79 mph requires in-cab signalling to be present.
  • Limited Speed: A speed not exceeding 45 mph.
  • Medium Speed: A speed not exceeding 30 mph.
  • Slow Speed: A speed not exceeding 15 mph.
  • Restricted Speed: A speed that will permit stopping within one-half the range of vision. It will also permit stopping sort of a train, a car, an obstruction, a stop signal, a derail, or an improperly lined switch. It must permit looking out for a broken rail. It will not exceed 15 mph.
  • Controlled Speed: A Speed that will permit stopping within one-half the range of vision. It will also permit stopping short of a train, a car, an obstruction, on-track equipment, or a stop signal.

Note: these definitions are specific to CSX, other railroad operators will often have their own terms and definitions. Make sure you get to know the right ones, as written above, for Sand Patch Grade!
