The new European toasters wouldn't last 20 years of what some of the GG-1s whent through for almost 50 years.No, you're right, they've gone through nearly 30 years of what the GG1s went through. And because the AEM7s came in on the backside of deferred maitenance they took the crappy track, the crap power systems, and everything else when they were new. The fact that the AEM7s are in as good a shape as they are today is a testament to their design. for a thicker piece of steel will save money when you don't have money to constantly repair due to cracks, and hardware failure. Except that the primary reason the GG1s were retired in the early 1980s was due to frame cracking. When designing a railcar, the best way to keep passengers safe is through structural rigidity. You could not be more wrong if you tried. A crash is all about disposing of kinetic energy in a way that does not injure the passengers. If your carbody is not designed to absorb any kinetic energy then it will keep ricochetting off stationary objects adjacent to the track. Every time the railcar bounces off another object is a moment where a passenger can sustain an injury or even die. Aside from that it's just a good idea to keep accidents from happening in the first place. There's a damn good reason the TGV has a nearly perfect safety record after all these years despite an operation which is completely unsafe by US standards. |
