  United  States  running cars upon tracks in this state for a distance of
  less than thirty miles, to heat its passenger cars on other  than  mixed
  trains,  excepting  dining cars, by any stove or furnace kept inside the

  necessary fuel; and in cars which have been equipped with  apparatus  to
  heat  by  steam,  hot  water  or  hot  air from the locomotive or from a

  propelled  by means of gasoline or oil engines may be heated in a manner
  to be approved by the commissioner of transportation. This section shall
  not be held to affect or interfere with the use by public authorities of
  this or other states, or of the United States, of stoves for heating  or
  cooking  or  boilers  for hatching operations in their fish car or cars.
  Any person or corporation  violating  any  of  the  provisions  of  this
