The Lymington branch from Brockenhurst to Lymington was electrified on 2 January 1967. Power was supplied at 750V DC on the third rail system.<ref name = gillham118>J C Gillham, ''The Age of the Electric Train'', Ian Allan Limited, Shepperton, 1988, {{ISBN|0-7110-1392-6}}, page 118</ref> An independent single branch line alongside the down main line between Brockenhurst and Lymington junction was provided when a new signal centre was opened at Brockenhurst from June 1978. The first train to use new alignment ran on 20 October 1978, after the derailment of a tamping machine prevented planned operation on the previous day.<ref name = paye12/><ref name = middleton69>Mitchell and Smith, captions to images 69 and 70</ref>
