The EMD F2 was a freight-hauling diesel locomotive built by General Motors Electro-Motive Division between July 1946 and November 1946. It succeeded the FT model in GM-EMD's F-unit sequence, and was replaced in turn by the F3. The F2 was in many respects a transitional type between those two; it kept the 1,350 hp (1,010 kW) rated D8 generator from the FT due to late development of the new D12 generator intended for the F3, but in a revised carbody design and internal layout that would be continued through the rest of the F-unit series. 74 cab-equipped lead A units and 30 cabless booster B units were produced.

  • EMD F2 byla dieselelektrická lokomotiva vyráběná během roku 1946 americkou firmou Electro-Motive Division (EMD), patřící do koncernu General Motors. Šlo pouze o přechodné řešení před zavedením nového modelu F3 do sériové výroby. (cs)
  • Die Baureihe EMD F2 war eine Diesellokomotivbaureihe des US-amerikanischen Herstellers Electro Motive Division (EMD). Sie kann als Übergangsbauart zwischen der EMD FT und der EMD F3 angesehen werden. (de)
  • EMD F2は1946年にGM-EMDで生産された電気式ディーゼル機関車である。最終組立はイリノイ州のラグレーンジ工場で行われた。F2は大いに成功したFシリーズ系列の2機種目である。 (ja)
  • F2型柴油机车是美国通用汽车电气动力分部(GM-EMD)在第二次世界大战结束后推出的一款干线货运柴油机车,也是继获得极大成功的FT型柴油机车的后继产品。1946年7月至同年11月期间,通用汽车电气动力分部共生产了104台F2型柴油机车,包括74台设有司机室的A节机车和30台无司机室的B节机车,主要用户包括、、伯靈頓鐵路、岩島鐵路等,墨西哥国家铁路也购置了该型机车。 F2型柴油机车的总体结构仍然与FT型柴油机车保持相同,同样采用流线型外观的整体承载结构棚式车体,机车走行部为两台布贝格B型二轴转向架。每节机车装用一台16气缸的16-567B型二冲程柴油机,与FT型柴油机车使用的16-567型柴油机相比,该型柴油机改进了辅助传动齿轮及气缸盖支座,额定转速仍为每分钟800转,平均有效压力提高到每平方英寸92磅(每平方厘米6.47公斤),燃料消耗量下降至0.382磅/有效马力·小时(173克/有效马力·小时),额定功率亦由1350马力提高至1500马力,但在F2型柴油机车上的装车功率仍然维持在1350马力,确保机车拥有较大的储备功率。除此之外,F2型柴油机车并采用经过改进的D12型牵引发电机和D27型牵引电动机,牵引齿轮传动比亦由4.13调整为3.81,最高运行速度相应由105公里/小时(65英里/小时)提高至113公里/小时(70英里/小时)。 (zh)
