Posted by aem7ac on Wed Feb 22 17:59:25 2006, in response to The MR90 is FRA compatible??? (was:Re: Metro-North New Haven Line on track for new cars), posted by WillD on Wed Feb 22 17:52:59 2006. Both the M7 and MR90 are listed with 800,000lb buff load ratings. As far as I know that's the primary way the FRA determines the crashworthiness of a given design.Buff load rating comes from sheer horizontal strength, nothing else. Horizontal strength doesn't have to be heavy. A single steel beam with people sitting on top would have enough buff strength, but isn't very survivable in a crash. I don't know what the other criteria are, but it is far more than just buff strength. AEM7AC |
