Section 227. Federal aid; receipt and expenditure

The comptroller is hereby
  authorized  to  accept  from the federal government or any department or
  agency thereof any moneys in any way granted, allocated  or  apportioned
  for  the  purpose of highway-railroad grade crossing eliminations or the
  reconstruction  or  repair  of  existing   grade   crossing   separation
  structures and deposit them in accordance with existing federal or state
  law  or  rules  or  regulations applicable thereto and the same shall be
  available for the  purposes  granted,  allocated  or  apportioned.  Such
  moneys  shall  be  available  to reimburse the state for its expenses in
  connection  with  a  grade  crossing   elimination   project   including
  incidental improvements rendered necessary or desirable by such project.
  The  expense of net benefit to be borne by the railroad company shall be
  the  lesser  of  (1)  the  amount  of  net  benefit  determined  by  the
  commissioner  in  accordance with this act or (2) the difference between
  the cost of the project exclusive of  incidental  improvements  and  the
  amount   of   federal  aid  for  the  project  exclusive  of  incidental
  improvements. State moneys made available for federal aid grade crossing
  elimination projects may be used in the first instance to pay the  costs
  of said projects.
