Wheatley's operating contract expired on 31 July 1880 and in the absence of offers from the CR and G&SWR, the WR board negotiated a renewal with Wheatley, on slightly less favourable (to him) terms. Wheatley now brought another engine, no. 6, into the fleet he operated: an 0-6-0 saddle tank "Bradby" that he had been using elsewhere on contract work. At about this time the 2-2-2 no. 1 was rebuilt as a 2-4-0. The 0-4-0 no. 4 seems to have been unsatisfactory and after a period laid up, was converted to an 0-4-2 saddle tank; after the conversion this locomotive proved much more useful.
