And just how much money are you prepared to throw down the PTC rat hole in order for it to be able to accomplish this?
Contrary to what you think, PTC is not a panacea and never will be.
Yes. Consider one possible scenario for this accident based on the small amount of info in the article:
Light power needs to "disable" PTC to get talked by the signal so they can enter the siding to make the pickup. After coupling onto the cars, an uncontrolled movement begins, perhaps by releasing handbrakes on a grade before the air is charged. They then roll out into the passing train on the main.
What would be the proposed action for PTC (whether cut-in or not) to override this (possible) crew failure and prevent the collision?
