49.—(1) Where, in accordance with the provisions of this Part of this Schedule, Network Rail affords to or secures for Cadent facilities and rights in land for the construction, maintenance and access to of alternative apparatus in substitution for apparatus to be decommissioned or removed, those facilities and rights must be granted upon such terms and conditions as may be agreed between Network Rail and Cadent and must be no less favourable on the whole to Cadent than the facilities and rights enjoyed by it in respect of the apparatus to be decommissioned or removed unless otherwise agreed by Cadent.
(2) If the facilities and rights to be afforded by Network Rail and agreed with Cadent under sub-paragraph (1) in respect of any alternative apparatus, and the terms and conditions subject to which those facilities and rights are to be granted, are less favourable on the whole to Cadent than the facilities and rights enjoyed by it in respect of the apparatus to be decommissioned or removed then the terms and conditions to which those facilities and rights are subject in the matter may be referred to arbitration in accordance with paragraph 56 of this Part of this Schedule and the arbitrator must make such provision for the payment of compensation by Network Rail to Cadent as appears to the arbitrator to be reasonable having regard to all the circumstances of the particular case.
