Midland Railway porters unloading milk at Somers Town fish and milk dock alongside St Pancras station, London. The churns had a capacity of 17 gallons and were stored in ventilated wagons. The railways precipitated a major shift in the urban diet and by the 1890s they were supplying about 50 million gallons of milk to London alone.
