Assessments shall not be made against land owned, leased or controlled by a railroad company, except that if there is a building on the land, the portion of railroad property subject to assessment shall be a lot whose frontage equals the actual front footage occupied by the building plus 25 feet on each side thereof, but not more than the amount of land owned, leased, or controlled by the railroad. If a building is placed on land that would have been subject to assessment but for the limitations imposed by this section after an improvement is made, then the railroad company shall be subject to an assessment without interest on the same basis as if the building had been on the  property when the improvement was made.

It is the intent of this section to make uniform the law concerning assessments against railroads. To this end, all provisions of law, whether general or local, in conflict with this section are repealed; and no local act taking effect on or after January 1, 1972, shall be construed to modify, amend, or repeal any portion of this section unless it shall specifically so provide by reference hereto. (1965, c. 839, s. 2; 1971, c. 698, s. 1.)
