 At this period Cockenzie Harbour was no longer much used due to the larger vessels then in use being unable to berth there, but for a period an exchange siding was made at Meadowmill, and the waggonway wagons were tipped into main line wagons for onward transport, generally to Leith.Twenty years later James Waldie and the other leading East Lothian coalmasters combined to form the Edinburgh Collieries Co. Ltd.The railway branch line, partly on the alignment of the earlier waggonway, was extended to Fleets Colliery.
