Overall weight is high no doubt but how is that weight distributed? Having been inside the power cars, I can tell you that they have a massive frame. I don't know the weight break-down either but my guess is that most of the added weight is in the power cars and that the trailers are actually pretty efficiently designed (i.e. relatively lightweight). Getting rid of the step wells surely helps keep their weight down. Conversely, adding wells will increase the weight.I know very well that the Acelas are not going to have a long service life, barely if even reaching their minimum design life, that there's little that can be done that is economically reasonable to cascade them down to a lower tier service or to a different corridor and that plenty of other equipment has or will outlast them. I also know that they weigh a lot. However, none of these are the reasons why Amtrak is replacing them so soon. The actual reason is not at all performance-based nor is it technical. It is almost purely commercial in nature. And note that I'm only presenting facts here, not opinions. |
