They could develop on the drawbar at and were designed for a top speed of , though they rarely saw these speeds. Slightly shorter but even heavier and more powerful were 2-6-6-6s built by Lima for the C&O and the Virginian between 1941 and 1948, which weighed and could produce up to at . The last Mallets These U.S. locomotives were paralleled to some extent by heavy-haul versions in the USSR, though without any attempt at faster running. Two 2-8-8-4 examples built in Russia in 1954–55 were probably the last Mallets built in Europe. Other continents Although it had found early favor in Europe, especially on lightly engineered railways, the Mallet type was generally superseded by the Garratt locomotive by the mid-1920s. In the Dutch East Indies, now the Republic of Indonesia, several types and sizes remained in use into the 1980s. In 1962, the Indonesian state railways DKA ordered a series of 0-4-4-2s, basically an updated version of the earlier Dutch design, for the old Atjeh (now Aceh) tramway. Constructed by Nippon Sharyo in Japan, they were the only Mallets built in Asia. In contrast to the rest of the Indonesian railways it has a gauge of , as to for the rest of the Archipelago. Smaller Mallets were used by plantations and other industries, all of the 0-4-4-0 type. These ran mostly on and gauge networks. But meanwhile in Garut - Cibatu in West Java, DKA ordered bigger 2-6-6-0 Mogul Mallets Like the extinct mallet tank Indonesian Railways CC10 Class and the even larger CC50 class along with the All extinct 2-8-8-0 Bull Moose like DD50 - 52 class. Only 3 CC50 engines survived. It was CC 50 01 ( Prototype ) in the Transportation museum in TMII, CC 50 22 in Railway Museum (Netherlands) and CC 50 29 in the Ambarawa Railway Museum. But unlike the CC 50 class, all of the CC 10s & DD 50 -52s was sadly cut up for scrap. We still hope for this engine to be preserved in railway museums, but there is a chance to make a new built of the class. Mallets were employed in Brazilian , tight-radius railroads. One Mallet ran in New Zealand, and is preserved at Glenbrook Vintage Railway, Auckland. Three Mallets ran in Australia, including one on the Magnet Tramway in Tasmania. Preservation Several Mallets have been preserved, some in operational condition. A number of
