(2) If at the commencement of this Act minerals lying under the outer area of protection are being worked by a mine owner, he shall, within one month after the commencement of this Act, give such notice as would after the commencement of this Act have been required to be given before such minerals were commenced to be worked, and, if such notice is so given, it shall be deemed for the purposes of the provisions of section seventy-eight of the Railways Clauses Consolidation Act 1845, as amended by this Act, to have been given more than thirty days before the date on which it is in fact given, and the minerals worked before the notice is given shall, for the purposes of the same provisions, be deemed to have been worked since the expiration of those thirty days. (3) Any mine owner shall be liable to contribute towards the expenses properly incurred by the railway company subsequent to the commencement of this Act in making good damage caused to any railway or works of the company by any working of minerals within the six years immediately preceding the commencement of this Act in like manner as if this Act had been in force at the date of such working; but, save as aforesaid, the mine owner shall be relieved of all liability to the company with respect to the working of any minerals prior to the passing of this Act, except a liability arising under an arrangement with the company. The provisions of subsections (2), (3), (4), (5) and (6) of section 79A of the Railways Clauses Consolidation Act 1845, as amended by this Act, shall apply in respect of the liability of a mine owner under this subsection in like manner as they apply in respect of his liability under that section.
