The DRG Class SVT 137 was a class of streamlined diesel railcars of the Deutsche Reichsbahn-Gesellschaft and later of the Deutsche Bundesbahn (as class VT 04) and the Deutsche Reichsbahn. With a regular maximum speed of and average speeds of up to they were the first high speed trains in central Europe. Subclasses and Technical Data Based on the prototype DRG Class SVT 877 there were four different subclasses and one experimental train: "Bauart Hamburg", two sections, Jacobs bogies, , 2’Bo’2’, No 137 149 - 152 and No 137 224 - 232 "Bauart Leipzig", three sections, Jacobs-bogies, , 2'Bo'Bo'2', No 137 153 – 154 and 137 233 – 234, DR 183 251 "Bauart Köln", three sections, 14 built, conventional bogies "Bauart Görlitz", , 2'Bo'+2'2'+Bo'2', 160 t, 132 Seats, No 137 273 - 278 and 137 851 - 858. "Bauart Berlin", four sections including a power / postal car, single slow running diesel , 2'Bo'+2'2'+'2'2'+Bo'2', 210.6 t, 126 seats, No 137 901 - 903 SVT 137 155, designed by the constructor of the Schienenzeppelin, Franz Kruckenberg, built 1934–1938, diesel-hydraulic, three cars, one powered cars at the head. Did not enter regular service. World speed record of (Hamburg-Berlin), June 23, 1939. The construction led to the DB Class VT 10.5, DB Class VT 11.5 and the DR Class VT 18.16 Most SVT 137 were diesel-electric, the SVT 137 Bauart Leipzig No 137 153 – 154 had a diesel-hydraulic transmission, the SVT No 137 233 – 234 had a diesel-electric transmission. Three sections of the SVT 137 902 were originally from the Dutch NS streamline '36 and used in this train. They didn't return to the NS after the war. History Since the success of the SVT 877 "Flying Hamburger" DRG projected a set of Diesel multiple units for a high speed network from Berlin to several German cities. First built 1934/1935, the "Bauart Hamburg" showed some differences to the prototype: The number of seats was 77 instead of 99, the placement of the seats 2+1 instead of 3+1. The Bauart Hamburg was longer. The main line Berlin-Hannover-Cologne started July 1, 1935; the route Berlin-Leipzig-Erfurt-Frankfurt followed August 15, 1935. From 1936 a service Berlin-Nuremberg-Munich/Stuttgart was initiated for a real success and struggling their routes. On February 17, 1936, the "Bauart Leipzig" achieved a world speed record of . These trains did the route Berlin-Breslau-Beuthen (now: Berlin-Wrocław-Bytom) from May 15, 1936. The scheduled time
