one Class 6C and two Class 6D locomotives. They were sold to the Sudan Railways Corporation in 1942. (Also see South Africa - Cape gauge) Sweden The Swedish class of B locomotives were of this arrangement they were used for both goods trains and high speed passenger services being built 1909-19 the locomotive was so successful three more locomotives were built in 1943-44 all locomotives were built by NOHAB. A relatively large number of the locomotives are preserved as it was one of the last steam locomotives in the strategic reserve and was kept in mothball storage until the 1990s. Switzerland The Swiss Class A 3/5 locomotives built by the Swiss Locomotive and Machine Works between 1902 and 1922 for the Jura–Simplon Railway, and the Gotthard Railway was of type 4-6-0. United Kingdom The first locomotive to be introduced in the United Kingdom was the Highland Railway's Jones Goods class of 1894, the first of which (No. 103) survives. Within five years, however, the wheel arrangement was being used primarily on passenger service, since British heavy freight trains were generally too slow to require a locomotive with a four-wheel leading bogie. Between 1906 and 1925, the became the most common express passenger locomotive type in everyday use in the United Kingdom, as a logical development from the 4-4-0 type that was previously used. The type continued to be used as mixed traffic locomotive until the end of steam in the United Kingdom in 1968. Pre-grouping era During the pre-grouping era, from 1899 to 1923, Wilson Worsdell of the North Eastern Railway (NER) used the type for his express passenger locomotives, the S and S1 classes of 1899 and 1900 that became the B13 and B14 classes of the London and North Eastern Railway (LNER) in 1923. Soon afterwards, these were followed by the appearance of other designs. John G. Robinson of the Great Central Railway (GCR) designed the Class 8 Fish Engines of 1902. In 1902 and 1903, George Jackson Churchward produced the 2900 Saint Class, which was the first in a long line of classes operated by the Great Western Railway (GWR). In 1903, Francis Webb of the London and North Western Railway (LNWR) followed with his unsuccessful four-cylinder compound locomotives of the 1400 Bill Bailey class. Between 1905 and 1910, altogether 105 locomotives of George Whale’s Experiment Class were built for the LNWR. Two notable express passenger designs
