Does anyone know how long does it take between alerter signals, and how long before a un-aknowledged alerter signal activates the brakes?
I ask because I was unaware the engineer was diabetic, I occured to me, if he had just reset the alerter, then had a sudden case of insulin shock and was incapacitated and he blacked out, and this was just prior to the train approaching the signal block, if he couldnt react to the red signal to slow the train down and it rolled thru the switch and almost immediatly into the UP frieght, was all this possible in the time frame between the alerter resets?
