 The line was heavily used for the shipment of bricks from the brickworks around Brill, and of cattle and milk from the dairy farms on the Wotton estate. By 1875 the line was carrying around 40,000 gallons (180,000 l; 48,000 US gal) of milk each year. Delivery of linseed cake to the dairy farms and of coal to the area's buildings were also important uses of the line. The line also began to carry large quantities of manure from London to the area's farms, carrying 3,200 tons (3,300 t) in 1872. As it was the only physical link between the Tramway and the national railway network, almost all of this traffic passed through Quainton Road station.
