Section 74. Care of steam locomotives; steam and water cocks; penalty

It
  shall be the duty of  every  corporation  operating  a  steam  railroad,
  within this state, and of its directors, managers or superintendents, to
  cause  the boiler of every locomotive used on such railroad to be washed
  out as often as once every thirty days, and to equip  each  boiler  with
  and  maintain thereon at all times, a water glass, showing the height of
  water in the boiler, having two valves or shut-off cocks,  one  at  each
  end  of  such  glass,  which  valves  or  shut-off  cocks  shall  be  so
  constructed that they can be easily opened and closed by hand;  also  to
  cause  such  valves  or  shut-off cocks and all gauge cocks or try-cocks
  attached to the boiler to be removed and cleaned whenever the boiler  is
  washed  out pursuant to the foregoing requirements of this section, also
  to keep all steam valves, cocks and joints, studs, bolts  and  seams  in
  such  repair  that  they will not at any time emit steam in front of the
  engineer, so as to obscure his vision. No locomotive shall hereafter  be
  driven  in  this  state  unless  the  same  is equipped and cared for in
  conformity with the provisions  of  this  section;  but  nothing  herein
  contained  shall  be  construed  to  excuse  the observance of any other
  requirement imposed by this chapter upon  railroad  corporations,  their
  directors,  officers,  managers  and superintendents. Every corporation,
  person or persons operating a steam railroad and violating  any  of  the
  provisions  of this section, shall be liable to a penalty of one hundred
  dollars for each offense, and the further penalty  of  ten  dollars  for
  each  day  that  such  violation  shall  continue.  The  commissioner of
  transportation shall enforce the provisions of this section.
