built for several railroads in several Russian and German factories from 1892 until 1907. All were two-cylinder compound locomotives with diameter coupled wheels. In 1896, 88 Baldwin-built four-cylinder Vauclain compound locomotives were introduced, designated V class (V for Vauclain, В in Russian). Also from 1896, Henschel-designed locomotives were introduced. Altogether 210 were built from 1896 to 1909, fourteen by Henschel and the rest in Russia. They were two-cylinder compound locomotives with diameter coupled wheels and were regarded as a more successful design than the A class. These locomotives were later designated as the Zh class (Ж in Russian). A development of the Zh class was the superheated Z class (З in Russian), of which 24 were built from 1902. From 1901 to 1903, stronger passenger locomotives were built, the G class (Г in Russian). These locomotives were of Vladicaucasian Railway and Bryansk factory design. Of these, 39 were built for the Vladicaucasian Railway and another 85 for Eastern Chinese railroads. They were two-cylinder compound locomotives with diameter coupled wheels. Some of these locomotives were later retrofitted with superheaters. The class U (У in Russian) was a four-cylinder oil-burning De Glehn compound locomotive which first appeared in 1906, initially on the Ryazan-Ural railroad. Of these, 62 were built at the Kirov Plant between 1906 and 1916. By the beginning of 1940, the inventory still listed 47 U class locomotives and the last of them were withdrawn in 1952. Lenin's locomotive, U class No. U-127 that was used during his funeral, is preserved at the Museum of the Moscow Railway. Altogether 145 heavier superheated K-class (К in Russian) passenger locomotives were built between 1907 and 1912. They were of Kolomna factory design and were two-cylinder simple expansion (simplex) locomotives with diameter coupled wheels. At the same time, the Briansk factory designed an improved superheated development of the G class that was produced between 1907 and 1914 as the B class (Б in Russian). Altogether 252 were built in Briansk and Lugansk. They were two-cylinder simplex locomotives with diameter coupled wheels that were quite successful in express work. Between 1911 and 1914, Kolomna built 39 stronger class locomotives ( in Russian) with diameter coupled wheels for faster trains. South Africa Eighteen classes of locomotives saw service in South Africa, sixteen on and two on narrow gauge. Of these, only two were conventional tank locomotives, while two others were delivered as tank-and-tender locomotives with
