The GE U18B diesel-electric locomotive was introduced by GE Transportation as a branch line road-switcher in 1973. It was the only North American locomotive powered by the 8-cylinder 7FDL engine. The U18B was not a popular seller with GE only making about 150 of them, and they were mostly purchased by Maine Central and Seaboard Coast Line. Railroads lost interest in specialized road units entering the 1970s. The U18Bs were noted for having reliability issues and being underpowered. The Maine Central referred to their U18Bs as the independence class and named their units after revolutionary war heroes. GE included information about a B18-7 locomotive (which would have followed the U18B) in its 1978 "Series-7 Road Locomotives" service manual, but none of these updated units were ordered, sold, or built. (en) U18B型柴油机车是美国通用电气公司于1973年推出的一款柴油机车，也是最后一款为北美本土市场提供的“通用”系列车型。这款机车是为重载调车和干线小运转任务而设计的四轴柴油机车，其主要竞争对象是易安迪的GP38-2型柴油机车。型号当中的“U”代表“通用”系列、“18”代表单节功率为1800马力、“B”代表机车轴式为Bo-Bo。 U18B型柴油机车采用底架承载的单司机室外走廊式车体结构。机车走行部为两台采用中心销牵引方式的二轴转向架，并且可按客户意愿选用通用电气的FB2型浮动摇枕式转向架，或者从已报废易安迪机车上换下来的布贝格B型转向架。机车装用一台八气缸、四冲程、涡轮增压的7FDL8型柴油机，额定功率为1800马力。传动系统方面，通用电气公司提供了直—直流电或者交—直流电传动两种方案供选择，但订购U18B型柴油机车的铁路公司都采用了成本较低的直—直流电传动装置，利用柴油机直接驱动一台GT-581型直流发电机，并将发出的直流电供给四台并联的GE-752E6型串励直流牵引电动机。 从1973年3月投入批量生产直到1976年10月停产为止，通用电气公司共生产了163台U18B型柴油机车，美国国内只有两家一级铁路公司（、）、一家二级铁路公司（）和一家公用事业企业（）订购了该型机车，而国外用户则只有墨西哥国家铁路。根据当时通用电气公司的产品发展计划，U18B型柴油机车的同级后继产品应为“Dash 7”系列的B18-7型柴油机车，但由于该型机车从来没有收到过订单，因此实际上亦只存在于通用电气的产品型录上。 (zh) |
