for the EMC-built welded underframes. The first three were built as EMC S/N 725-727 for the Atchison, Topeka and Santa Fe Railway as their #2350-2352, later renumbered #2400-2402 and rebuilt into SW1200s in 1959. Two were constructed as S/N 728 and 729 for the Philadelphia, Bethlehem and New England Railroad as their #210 and 211, later renumbered as #53 and 54. Another two were built as S/N 730 and 731 for the Kansas City Terminal Railway as their #60 and 61. The final NW, S/N #732 was built for the Northern Pacific Railway as their #100. NP 100 was rebuilt to an SW900m in Jan 1957. It was in service on the Burlington Northern with same number and sold in 1983. NW1 The NW1 was the only 201-A-engined N series locomotive model to be ordered in any significant number; 27 were built between November 1937 and January 1939. It had a lengthened hood and no electrical box in front of it as in the other N series models. Electrical equipment was General Electric. Owning railroads were: Elgin, Joliet and Eastern Railway: 2 locomotives, #400-401 Lehigh Valley Railroad: 11 locomotives, #120-130 Chicago, Burlington and Quincy Railroad: 2 locomotives, #9200-9201 Great Northern Railway: 1 locomotive, #5102 (rebuilt to an SW8 #101) Chicago, Rock Island and Pacific Railroad: 8 locomotives, #700-707 Chicago and North Western Railway: 1 locomotive, #901 Minneapolis and St. Louis Railway: 2 locomotives, D538 (now preserved at the National Railroad Museum, Green Bay, Wisconsin) and D738 NW1A The NW1A, of which only 3 were built, was equipped with EMC-built traction motors, although the generator was still a General Electric unit. All were built for the Soo Line: EMC S/N 841-843, SOO #2100-2102. NW4 The NW4, of which two examples were built for the Missouri Pacific Railroad, used the hood and cab configuration of the regular N-series, but with an additional straight section between cab and hood, mounted on a lengthened frame with large air tanks on the front platform, in front of the radiator. The additional hood section contained a steam generator; The water tanks were mounted beneath the frame; the air tanks were therefore displaced to the front. The locomotives ran on AAR type B trucks re-used from EMC boxcab demonstrators #511 and 512. The two NW4s were EMC S/N 823 and 824, and were MP #4102 and 4103. They were scrapped in 1961.
