Section 84. Railroad and highway crossings

Whenever it shall be necessary
  for any line of pipe of any such corporation to cross  any  railroad  or
  highway, such line of pipe shall be laid under such railroad or highway,
  with  the least injury practicable, and unless such right to cross shall
  be acquired by agreement, compensation shall be  made  to  the  railroad
  corporation,  or  in  case  of  highways,  to  the public, in the manner
  prescribed in the eminent domain procedure law, but no exclusive  right,
  title  or  use  shall be so acquired against a railroad corporation, nor
  against the public in a highway. No such corporation shall take  or  use
  any  lands,  fixtures  or  structures  of  any  railroad corporation, or
  acquire pursuant to the provisions of the eminent domain procedure  law,
  any  right or title to the lands of any such corporation, except for the
  purpose of a direct crossing.
