If in the opinion of the public utilities commission any system of interlocking works or fixtures referred to in section 4907.50 of the Revised Code proves to be unsafe or impracticable, the commission may order than no engines or trains shall pass over any such crossing or bridge without stopping, and the laws regulating the running of engines and trains shall apply. Before such order is made or enforced the commission shall give such railroads opportunity to be heard as to the propriety of the order.
