ยง  116.  Redemption of unused passage tickets.  Every person who shall
  have purchased a passage ticket from an authorized agent of  a  railroad
  company, which shall not have been used, or shall have been used only in
  part, may, within thirty days after the date of the sale of said ticket,
  present  the same, unused or partly used, for redemption, at the general
  office of the railroad company which  issued  said  ticket,  or  at  the
  ticket office where said ticket was sold, or at the ticket office at the
  point  to which the ticket has been used.  If said ticket wholly unused,
  shall be presented for redemption at the ticket office where  sold,  the
  same  shall  be  then  and there redeemed by the agent in charge of said
  ticket office at the price paid for said ticket. If said ticket,  partly
  used, shall be presented for redemption at the ticket office where sold,
  or  at the ticket office at the point to which used, the ticket agent at
  either of said offices, upon delivery of said ticket, shall issue to the
  holder thereof a receipt, properly describing said  ticket  and  setting
  forth the date of the receipt of said ticket, and the name of the person
  from  whom  received, and shall thereupon forthwith transmit said ticket
  for redemption to the general office. It shall  be  the  duty  of  every
  railroad  company to redeem tickets presented for redemption, as in this
  section provided for promptly and within not to exceed thirty days  from
  the  date  of presentation at the general office or from the date of the
  aforesaid receipt. A wholly unused ticket shall be redeemed at the price
  paid therefor. A partly used ticket shall be redeemed at  a  rate  which
  shall  be  equal  to the difference between the price paid for the whole
  ticket and the cost of a ticket of the same class between the points for
  which said ticket was actually used. Mileage  books  shall  be  redeemed
  within  thirty days after the date of the expiration thereof in the same
  manner. Provided, however, that nothing herein contained shall be deemed
  to prohibit the requirement by tariff of advance notice of  cancellation
  as a condition to the redemption or use of passage tickets in connection
  with which reserve accommodations have been obtained; provided, further,
  that   nothing   herein  contained  shall  be  deemed  to  prohibit  the
  establishment by tariff of a service charge for the redemption of wholly
  unused or partly  used  tickets.  Every  railroad  company  which  shall
  wrongfully  refuse  redemption,  as  in this section provided for, shall
  forfeit  to  the  aggrieved  party  fifty  dollars,  which  sum  may  be
  recovered,  together  with  the  amount of redemption money to which the
  party is entitled, in an action in any court of competent  jurisdiction,
  together  with  costs;  but  no  such  action  can  be maintained unless
  commenced within one year after the cause of action accrued.
