241 (serial no 1613) and 242 (serial no 1614), respectively. In 1937–1938, locomotive 242 (serial no 1614) was rebuilt as a 2-4-4-0 tender locomotive at the SM workshop in Divinópolis, MG. At the completion of this rebuild, the locomotive's operating number was changed to 330. During 1938/1939, the SM was merged with the Estrada de Ferro Oeste de Minas (OM) and various smaller railway companies in Minas Gerais to form the Rede Mineira de Viação (RMV). In 1939, all affected locomotives were renumbered. Locomotive no 330 (ex-SM 242, serial no 1614) received a new RMV holding number 156. However, as early as 1941 the RMW placed that locomotive out of service. Meanwhile, in 1938, the SM had undertaken the same rebuilding work in Divinópolis to locomotive 241 (serial number 1613), and had renumbered it 331. It is possible that this latter rebuild was never completed; in the RMV annual report for 1940, locomotive 331 (ex 241) was recorded as being out of service. Another indication that the work on locomotive 331 (ex 241) was never completed is the fact that it appears never to have been given a new RMV operating number. It is not even clear which of the two possible new numbers 155 and 157 would have been allocated to that locomotive. By 1944, neither locomotive was still appearing in the RMV locomotive lists. Presumably, they both suffered the fate of most steam locomotives in Brazil in the 1940s and 1950s: demolition.
