8. The railway administration may, for the purpose of exercising the powers conferred upon it by this Act, alter the position of any pipe for the supply of gas, water or compressed air or the position of any electric wire or of any drain not being a main drain:
(a) when the railway administration desires to alter the position of any such pipe, wire or drain, it shall give reasonable notice of its intention to do so, and of the time at which it will begin to do so, to the Local authority or company having control over the pipe, wire or drain, or, when the pipe, wire or drain is not under the control of a local authority or company, to the person under whose control the pipe, wire or drain is;
(b) a local authority, company or person receiving notice under proviso (a) may send a person to superintend the work, and the railway administration shall execute the work to the reasonable satisfaction of the person so sent and shall make arrangements for continuing during the execution of the work the supply of gas, water, compressed air or electricity or the maintenance of the drainage, as the case may be.
