Section 62. Sleeping and parlor cars

Any railroad corporation may contract
  with any person, association or  corporation  for  the  hauling  by  the
  special  or  regular  trains  of  said railroad corporation, the parlor,
  drawing-room or sleeping car or cars  of  such  person,  association  or
  corporation, in which extra accommodations shall be furnished, for which
  said   person,   association  or  corporation  furnishing  such  parlor,
  drawing-room or sleeping car or cars, may charge for  the  carriage  and
  transportation   of   persons   and   property   therein,  a  reasonable
  compensation for such extra accommodation, in addition to the  fare  and
  charges  now  allowed  by  law  for  the  carriage and transportation of
  passengers  and  property  in  the  ordinary  cars  of   said   railroad
  corporation.  But  said  railroad  corporation  so  contracting shall be
  liable in the same way and to the same extent as if the said car or cars
  were owned by it, and shall furnish sufficient  ordinary  cars  for  the
  reasonable accommodation of the traveling public.
