Buccleuch instituted a ferry service from Granton to Burntisland in September 1844, and the success of this route eclipsed the service from Newhaven and Trinity across the Forth. This took away most of the traffic of the Edinburgh, Leith and Newhaven Railway, which did not come close to Granton. Seeing this difficulty approaching, the EL&HR submitted a Bill to Parliament for an extension of their line to Granton, and on 19 July 1844 the Act received the Royal Assent. The Company name was changed to the Edinburgh, Leith and Granton Railway, and as well as the Granton extension a branch from Warriston to Leith was authorised. The Granton extension was opened on 19 February 1846. A new and attractive station at Trinity was part of the scheme; the line ran west from there, turning north on to the pier at Granton. The line from Warriston to Leith opened on 10 May 1846.
