 The first revenue-earning train ran on 17 March 1851 over a short section of line to Kinneil Iron Works; the line was still in the hands of the contractor at this time.However the line between Bo'ness High Junction and Bo'ness Harbour opened fully in early August 1851, with the low level line being opened on 22 December 1851.In the intervening period, all through traffic travelled via the E&GR connections, including the backshunt there.
