For real this time. Think about this, the brakes on trains require that one of the engines be running at all times for the brakes to work; if there isn't an engine running, the brakes release. I know that currently the RR company is blaming the engineer, saying that he did not set all 7 sets of brakes. First they tried to blame the firefighters that had been called in a couple hours prior - saying that they must have - turned the engine off, released the braks, hit the override. Trains have a 'dead man' switch so that if there is no one operating the controls, it automatically stops. I am sure there is a reason that the braking system requires an engine to keep the brakes 'on' rather than requiring an engine being on to keep the brakes 'off' but I sure can't think of it right now.

My condolences to the friends and families of casualties in Lac-Mégantic, Quebec, Canada - our hearts go out to you.
