BL2在内燃机车的领航员EMD上是个错误

EMD的BL2柴油机车是一个历史性的错误. 在20世纪30年代和40年代,柴油机车的销量从阴燃的灰烬增长到白热化的火海. (1940年后,通用汽车的电动部门)似乎不会犯错. 在通用汽车的技术和营销力量的支持下, EMD developed powerful, rugged diesel engines; built a state-of-the-art diesel-locomotive factory at La Grange, Ill.; and consistently fielded products that were just what the railroads needed to rid themselves of steam locomotion. The SW and NW switcher lines, E-series passenger models, F家族(主要是)货运单位构成了一个成功的全明星目录,其他任何建筑商都无法与之匹敌. EMD was the leader; the others played catch-up.

But at the height of its postwar prosperity, EMD犯了一个令人难忘的错误:BL2内燃机车及其原型, the BL1. Although competitors Alco, Baldwin, 费尔班克斯-莫尔斯早在1941年就开始生产道路开关式的柴油机车, EMD was reluctant to offer one. Instead, it dressed up the innards of the 1,500马力的F3驾驶室位于半流线型车体上,带有一个倾斜的发动机舱,以提供后方视野和用于切换工作的终端平台. 理论上,这一装置的出现是为了使其在郊区和当地的客运列车上具有吸引力.

情人眼里出西施,但很少有人会说这种设计“有吸引力”.” Trains Editor David P. 1947年9月,Morgan在参观了EMD的工厂后说:“当我第一次看到BL1原型机在EMD的施工地板上时,. . .], I wondered if all was well.”

The “BL” designation stood for “Branch Line,反映了该单位在次要任务上的预期服务. 但铁路公司往往不会为这类工作花钱购买新能源, 更倾向于将旧的火车头串联起来,以降低利用率. (唯一的一辆演示车BL1与生产车型相比有一个空气节流阀和其他一些机械上的细微差别, and was soon rebuilt to BL2 standards.)

The BL2 was not a good seller. Its complex carbody was expensive to produce, 很难接近发动机和发电机, 而且它的轻量化的框架使它远离了重型服务. 虽然车体门可以通向终点平台, 与真正的道路切换装置相比,这种安排显得笨拙.

从1948年2月到1949年5月,EMD只建造了59台BL型机车. Nine railroads bought it: Bangor & Aroostook (8); Boston & Maine (4); Chesapeake & Ohio (14); Chicago & Eastern Illinois (2, plus the reclassified BL1 demonstrator); Florida East Coast (6); Missouri Pacific (8); Monon (9); Rock Island (5); and Western Maryland (2).

铁路公司真正需要的是一名真正的EMD改道者. 1949年10月,当第一批GP7示威者离开La Grange时,他们得到了它.

Seven BL2s survive, thanks mainly to Bangor & 当柴油保护时代开始时,Aroostook和西马里兰仍在运行他们的汽车. 到1972年,大多数所有者都把他们的bl2型股票换成了EMD型股票. 然而,就在那一年,出现了第一个为后代保留BL的人,命名为L&N公司将处于可操作状态的Monon 32号列车捐赠给肯塔基州铁路博物馆.

  1. 当时北溪短线还在萨拉托加和北溪之间运行, NY several years ago (~2013), 我在北溪站的旅客月台漫步, looking at this strange diesel locomotive. 回家后,我查看了柴油发动机设计,惊讶地发现D&H locomotive was a BL2.

  2. 你可以说我古怪,但我一直喜欢BL2的外观. Used to enjoy seeing the Wisconsin & Calumet BL2 (lettered Janesville & (东南方向)跑向城镇南部,“回到过去”,在去芝加哥的路上.

  3. Growing up I was all about the Monon. 它穿过我家乡的街道,使我成为一个真正的火车狂热者. 当然我最喜欢的N级单位是Monon BL2. 我认为这是一种独特的美,我很高兴一些完整的操作示例在开车到我家的距离内.
