Section 147. Powers of corporations organized to acquire and operate railroads partly in the state

A railroad corporation created under the
  laws of the state or states in which the greater part of the line of its
  railroad may be  situated,  or  a  railroad  corporation  heretofore  or
  hereafter  created  under  this chapter or other statutes of this state,
  for the purpose of taking title to, and operating, the line of  road  as
  so  sold,  under  a judgment or decree of a court of this state, or of a
  court of the United States sitting in this state, for the foreclosure of
  a mortgage, with its franchises and appurtenances, may hold, possess and
  operate not only those parts of the railroad lying in other states,  but
  also  that  part  of  the line of such railroad lying in this state, and
  shall be subject to the duties and liabilities to which such corporation
  was, by the laws of this state, subject, and to such  further  or  other
  duties  and  liabilities  as  are now or may hereafter be imposed by law
  upon railroad corporations of this state, and to the provisions  of  any
  other   statute   of   this   state  concerning  the  reorganization  of
  corporations. An exemplified copy of the certificate or certificates  of
  incorporation,  under  and  by  virtue  of which any such corporation is
  created in any other state, and a certified  copy  of  the  judgment  or
  decree  of  any  court  sitting  in  any  other  state, under which said
  railroad shall have been sold, and a certified  copy  of  the  order  or
  judgment  or  decree  of  confirmation  and  approval  required  by  the
  preceding section, or of the order, judgment or decree of the  court  of
  this  state,  or  of  the United States in this state, which decreed the
  sale, confirming  the  same,  shall  be  filed  in  the  office  of  the
  department  of  state  for  this  state, and in the office of the county
  clerk of the county where its principal business office in this state is
  or shall be located.
    This section and the preceding one shall apply in respect of  decrees,
  foreclosures,  sales, confirmations, reorganizations and incorporations,
  whether heretofore or hereafter made, provided, however, that nothing in
  either of said sections shall affect any action or proceeding pending in
  any court, on or before the first day of  April,  eighteen  hundred  and
  ninety-six,   to   establish   the  invalidity  of  any  foreclosure  or
  reorganization theretofore had, or to  enforce  any  judgment  or  claim
  arising before such foreclosure or reorganization.
