Article 5 - (Railroad) STREET SURFACE RAILROADS
192 - Center-bearing rails prohibited.

  192.  Center-bearing rails prohibited.   No street surface railroad
  corporation shall hereafter lay down in the streets of any  incorporated
  city  or village of this state what are known as "center-bearing" rails;
  but in all cases, whether in laying new track or in replacing old rails,
  shall lay down "grooved" or some other kind of rail not "center-bearing"
  approved by the local authorities. Such grooved or other rail  shall  be
  of  such  shape  and  so  laid as to permit the paving-stones to come in
  close contact with the projection which serves to guide  the  flange  to
  the  car  wheel.  Where  in any city, the duty of repairing and repaving
  streets,  as  distinguished  from  the  authorization  of  such  paving,
  repairing  and  repaving,  is by law vested in any local authority other
  than the common council of such city, such other local  authority  shall
  be the local authority referred to in this section.
