How does a modern locomotive's dead-man control work? If it's still the old dead-man pedal, could a modernized version perhaps using motion sensors or something requiring some kind of control movement within a certain time be used to sound a warning and/or stop the train?? Aircraft have all kinds of warning bells & whistles and as with modern cars, once a computer is used for one thing, it easy to add other features. Corporations will usually complain about almost any cost, but a recent Trains had an article about BNSF installing video cameras to record grade crossing incidents and I always have to wonder where railroads find the money to pay for mergers i.e. what's U.P.'s annual interest expense on bank loans?? <br /> <br />I also wonder how the potential destructive energy of a loaded double stack at 70 mph compares to a 767 hitting the WTC towers???
