- 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. There are no reliable recognition features for an F2. They were built with what has become known as 'Type 1' side panels, with three portholes and no filter grilles, but this was carried over into early F3 production and in any case, could be changed later by the customer. Like some early F3s, they were built with small side numberboards on the nose. They, and all subsequent F-units, are readily distinguished from the FT by having two exhaust stacks instead of four, and by having no large overhang on the end of the B units, while the trucks were a little further away from the other ends. They also had four radiator fans at the center of the unit next to each other in line on the roof instead of two at each end. This external feature was the result of a major change in internal arrangement, the replacement of all mechanical and belt-drives for radiator fans and traction motor blowers with electric motors. Power for these accessories was produced by a new D14 three phase alternator built into the main DC generator, called a “companion alternator”. This device has been used in all later EMD road locomotives to the present. All F2's were scrapped, making them the only EMD F-unit model with no extant examples. (en)

- 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)
