Despite sales for the model being slow, at least compared to other designs GE had sold up to that time, it soldiered on in active revenue service on Class Is for many years with the final units being retired from CSX in the late fall, 2009. Earlier, Conrail's original fleet of B36-7s were put out to pasture between 2000 and 2001. In any event, for GE it understood by the 1980s that any remaining interest in four-axle designs, at least for main line service (this model, for instance, had been intended for use in fast intermodal/container service, which is why Conrail like them so well) had all but evaporated.请你这位大神可以再细点研究为啥GE这车型的低销量,或许我的观点有误
