This saves railroad massive pension plan expenses (the number one unfunded liability for transport companies) and other expenses, and averts the risks of strikes. Computer automation never Unionizes. The MSM used to always include whether or not the engineer who crashed had been over the alcohol or drug limit.
The last several bomb trains, there's been zero mention of this previously hot topic for journos. It's not adding up. One of the Canadian crashes the railroad claimed that the engineer stepped off to make a phone call and the train took off by itself.
