Designated as Class I, a ninth followed within six months. Beyer Peacock also built six 2-6-2T tank locomotives in 1887 (Class II) and three further 2-6-2T (Class III) were built by Kitson and Company in 1892. The 0-6-4Ts were built with steam and vacuum brakes and steam reversing gear and weighed . The 2-6-2Ts were fitted with vacuum brakes only; those built by Beyer weighed and Kitson's . As electrification progressed, the old rolling stock was advertised for sale. An attempt to sell the 18 locomotives and 96 carriages by auction in June 1903 proved completely unsuccessful – the auctioneer had to remind the bidders that he was not selling scrap. It was September before the first locomotive was sold; it would take another two years to sell all-bar-one of the locomotives. The last locomotive — which had been retained for working permanent way trains — was sold in January 1908. The first to be sold was No. 5 "Cecil Raikes", which was bought by Shipley Collieries for £750 (equivalent to £ in ). They came back and bought No. 8 for £650; but not before Alexandra (Newport and South Wales) Docks and Railway had bought all six of the Class II locomotives for £3450 (equivalent to £ in ). They became ADR 6–11 (not in order). Alexandra Docks later bought four more locomotives: Three 0-6-4T (nos. 2, 3 & 6), and one Class III 2-6-2T (no. 16), these becoming 24–22 and 25. All ten ADR locomotives passed to the Great Western Railway in January 1922, and were withdrawn between January 1923 and May 1932. The other two Class III locomotives were bought by Whitwood Colliery for £1240. The last four locomotives (nos. 1, 7, 9 and 4) were sold to J. Brown Limited (as their Nos. 5–8) for use on the Richmond Vale railway line in New South Wales, Australia. No. 4 "Gladstone" had been retained by the Mersey Railway until 1907 for departmental use, but was then replaced by Metropolitan Railway A Class (4-4-0T) No. 61, built by Beyer Peacock. This was replaced in 1927 by an earlier Metropolitan Railway 4-4-0T, No. 7.
