1. If in the judgment of the division of motor carrier and railroad safety, additional terminals or terminal facilities, stations or any other property, construction, apparatus, equipment, facilities or device for use by any motor carrier in connection with the transportation of passengers or household goods ought reasonably to be provided, or any repairs or improvements to or changes in any thereof in use ought reasonably to be made, or any additions or changes in construction should reasonably be made thereto in order to promote the security or convenience of the public or employees, or in order to secure adequate service or facilities for the transportation of passengers or property, the division shall, after a hearing, either on its own motion or after complaint, make and serve an order directing such repairs, improvements, changes or additions to be made within a reasonable time and in a manner to be specified therein, and every motor carrier is hereby required and directed to make all repairs, improvements, changes and additions required of it by any order of the division served upon it.

2. If any repairs, improvements, changes or additions which the division has determined to order require joint action by two or more of said corporations, the division shall, before entry and service of order, notify the said corporations that such repairs, improvements, changes or additions will be required and that the same shall be made at their joint cost, and thereupon the said corporations shall have thirty days or such longer time as the division may grant within which to agree upon the part or division of cost of such repairs, improvements, changes or additions which each shall bear. If at the expiration of such time such corporations shall fail to file with the division a statement that an agreement has been made for a division or apportionment of such repairs, improvements, changes or additions, the division shall have authority, after further hearing, to fix in its order the proportion of such cost or expense to be borne by each corporation and the manner in which the same shall be paid and secured.
