Two 0-8-0T locomotives from the Avonside Engine Company, delivered in 1866 and numbered 472 and 473. These were designed for hauling coal trains to Farringdon Street and to South London via Snow Hill. Six locomotives were ordered but the last four were cancelled because the first two proved ill-suited to the route because of their long rigid wheelbase. For passenger services, "120 class" 0-4-4WT locomotives 621-628 (built 1872) were used. These had inconspicuous condensing apparatus with the pipework hidden from view.
