 This arrangement was confirmed by Act of Parliament of 27 July 1892, and incidentally included transfer to joint control of steamers on Loch Lomond.From Dumbarton Junction the NBR line to Balloch was to be transferred to joint control, between the NBR, the L&DR and the Caledonian Railway, on the day that the L&DR opened its line for passengers to that point.The joint section would be called the "Dumbarton and Balloch Joint Railway".
