locomotive type was the Austro-Hungarian IId class of the Kaiser Ferdinands-Nordbahn (KFNB). It was built from 1895 and later became the 308 class on the Imperial Royal State Railways (kaiserlich und königlich Staatsbahnen, kkStB). It was followed from 1901 by the XVIb class of the Austrian Northwestern Railway (Österreichische Nordwestbahn, ÖNWB) that later became the kkStB class 208, and then by the kkStB 108 class. They were not numerous, though. All three classes together numbered a little more than one hundred locomotives. Apart from the Austrian locomotives, the Hungarian State Railways (Magyar Államvasutak or MÁV) also operated some Atlantic classes. Belgium In 1939, the National Railway Company of Belgium (NMBS/SNCB) introduced six Class 12 streamlined Atlantic locomotives on the fast lightweight boat trains that ran on the line between Brussels and Ostend. Designed by Raoul Notesse to be capable of speeds of and based on the successful Canadian Pacific Railway 4-4-4 Jubilee type semi-streamlined locomotives, but incorporating the ideas on streamlining of André Huet, they were built by John Cockerill at Seraing. They were fully streamlined, except for openings to provide access to the valve gear and motion, and had inside cylinders with outside valve gear to reduce oscillation at speed. The class remained in service until 1962. Germany The Atlantic, known in Germany as the 2'B1' wheel arrangement, enjoyed some short-lived popularity in the German states. Between 1902 and 1906, the class of the Prussian state railways was built to two competing designs, 159 locomotives to the design of August von Borries and 79 locomotives to that of Alfred de Glehn. Between 1908 and 1910, Hanomag built 99 Prussian S 9 locomotives. All were four-cylinder compound engines working on saturated steam. The Prussian Atlantics were withdrawn shortly after the First World War and some were given to France, Belgium and Poland. Atlantics were also adopted in some other German states. Twelve Pfalz P3.1 class locomotives were built for the Palatinate Railway (Pfalzbahn) from 1898. In addition, eleven Pfalz P4 class locomotives were built from 1905. Fifteen Saxon X V class locomotives were built for the Royal Saxon State Railways from 1902. Eighteen Baden IId class locomotives were built for the Grand Duchy of Baden State Railways from 1902. In 1900, the Royal Bavarian State Railways imported two 4-4-2 locomotives from Baldwin Locomotive Works in the United States of America and classified them Bavarian S 2/5. Ten more locomotives were
