No one on those occasions got their "face smashed in". That was before phones and even ipods, so people were less oblivious.PCCs had various top speeds, I believe Chicago had them geared for over 60mph. In this crashe train is in no way at fault, and a higher braking rate would not have prevented it. More e-brake does have two advantages that I can think of: avoiding or decreasing the severity of rare train-to-train crashes, and the same for a crash with load of steel, cement or the like stuck on a grade crossing. In the latter case the engineer can see the truck from 1000 feet away, but can do very little about it. Road-going cars stop at rates in excess of 24mph/sec; some approach 30 though none have quite reached it. Obviously, if a train could stop at those rates it would not be advisable; in a car that rate has any junk not tied down flying and the passengers screaming. Train standees would go over like bowling pins. But it's also not a large acceleration; it's just over 1g, about what you experience lying on your stomach. |
