The dust having settled, in 1972 THR formally acquired the Rolls-Royce locomotive business and Rolls-Royce Motors increased its holding in the Company. Whilst only now was the transfer of the locomotive business formally concluded, in practice the last Sentinel locomotive was delivered in March 1971, with only three the previous year, and in the same two years the Company built and delivered both 0-4-0 and 0-6-0 Vanguard locos, including three 0-4-0 locos to Indonesia. These were the first Vanguard locos to be exported and were to the order of Shell Petroleum at the Hague.
