2023 New York Laws › RRD - Railroad › Article 3 - Construction, Operation and Management › 78 - Coal Jimmies and Caboose Cars.

§  78.  Coal  jimmies  and  caboose  cars.  The  use of cars known and
  designated as "coal jimmies" in any form and the use of  any  car  as  a
  caboose  unless  it  shall have a suitable and safe platform at each end
  thereof, and the usual railing for the protection of persons using  such
  platform,  shall  be unlawful within the state, except upon any railroad
  whose main line is less than fifteen miles in length and  whose  average
  grade  exceeds  two  hundred feet to the mile. This section shall not be
  construed to authorize the interchange of such "coal jimmies" with,  and
  the  use thereof upon, railroads of more than fifteen miles in length or
  whose average grade is less than two hundred feet to the mile.
From and after the first day of July, nineteen hundred and twenty-four
  it shall be unlawful for any corporation or individual to man, equip, or
  to use within the state on any railroad a caboose car, or car  to  serve
  the  purpose of a caboose car, which shall be less than twenty-four feet
  in length exclusive of the  platform,  or  which  shall  have  a  center
  constructive strength less than that of the fifty-ton freight cars built
  according  to  master  car  builders'  standards.  Such caboose or other
  equivalent car shall be constructed with steel  center  sills  with  two
  four-wheeled trucks; with each platform not less than twenty-four inches
  wide,  with  proper  guard  rails,  grab irons and steps, which shall be
  equipped with a suitable rod, board or other guard designed  to  prevent
  slipping  from the car step. Each such car shall have a door at each end
  and shall be equipped with four separate sleeping berths not  less  than
  six  feet  and  two  inches  in  length.  Each  such car shall contain a
  properly furnished toilet room, sink,  icebox,  water  cooler,  clothing
  lockers, fire extinguishers, and with either a cupola of sufficient size
  to  accommodate  at least two men or bay windows. Each such car on every
  freight train shall be equipped  with  electric  markers  of  sufficient
  candle  power  to be visible for a distance of three thousand feet under
  normal weather conditions. Flashing type  or  constant  burning  markers
  shall  be deemed a sufficient compliance with the foregoing requirement.
  The  glass  in  all  windows  and  doors  of  each  such  car  shall  be
  shatterproof.  Whenever  any  caboose or other car used for like purpose
  now in use by any such railroad company shall, after this act goes  into
  effect,  be  brought  into  any  shop  for  general  repairs it shall be
  unlawful to again put the same into use within this state, as a  caboose
  or  other car used for like purpose unless it be equipped as provided in
  this act. All cabooses  built  after  January  first,  nineteen  hundred
  sixty-five  must  be  of  steel  construction and equipped with electric
  lights.
This section shall not apply to cabooses or other equivalent cars used
  in the switching service or on trains operated wholly within twenty-five
  miles of yard limits.
Any  violation  of  the  provisions  of  this  section  shall   be   a
  misdemeanor,  punishable  by a fine of not less than one hundred dollars
  nor more than five hundred  dollars  for  each  separate  offense.  This
  penalty  is  in  addition  to that provided for in section eighty-one of
  this chapter.
