This is also why sometimes doors in a particular car will not open at a random station stop, because the car thinks its still moving, not allowing the doors to open.
You would still not lose a doorlight.
However, the "no motion" system does not override the sensitive strip system which when there is an object stuck in the door, it reopens. that is the sensitive strip system.
So, even if the crew was totally incompetitent, and the brakeman gave the engineer 2 to go, and all the doors were wide open and people were unloading, these systems would NOT be over riden - they would still work - the doors would close in each car once the car sensed motion, and if someone was in the door, it would bounce back open once it felt the resistance of something (person, object, etc). This would give that unfortunate person an opportunity to either get their body parts back on the train, or get the rest of the way off the train. And with the breakneck acceleration of a '40 with 5 cars (that what this train was in bradley beach) it would give the person a handful of seconds to react.
Only MUs allow there to be a door open with a key in the panel and allow the engineer to draw traction power. All of the other comets (2, 3, 4, 5), and im ASSUMING the MLs do not allow ANY doors to be open and the engineer draw traction power, unless in bypass. Once the train starts rolling, you cannot open a door, and if you managed to (say with the emergency handle on a C5) the engineer would loose his door light, and traction power. If the locomotive was in end door bypass, the end door could be left open, with or without a key in the panel, however, as soon as the car started rolling and the car sensed the movement, the car would try to close the door itself, that is the no-motion system.
Again, its not as "cut and dry" as the newspapers are making it out to be. I still FIRMLY believe that the victim tried to get back on the train after it started moving, fell off, and was injured/killed that way. Again, the actions of the crew, in particular the brakeman, might have been a factor, but not the only factor.
