Brown said Norfolk Southern, the Atlanta-based railroad operator, had 579 violations in cases that have been closed and paid an average fine of less than $3,300 in the most recent fiscal year available.
"The company, keep in mind, planned to spend $3.4 billion on stock buybacks and they already did that and even more, right before, and they were about to do it again when the train derailed," Brown said. "It's now a cost of doing business, the fines, it really is a rounding error."
