 The normal electric service was finally resumed after modifications to the electrical equipment in the trains on 1 October 1961.The ordinary running of steam trains on the L&DR route to Glasgow continued until 1964, when that line was closed.The entire former L&DR network was now closed to passenger operation, except for the section between Dunglass and Dumbarton Junction, which carried the new frequent electric passenger service, currently (2015) operated by Abellio ScotRail.
