But that may be too low to cover the costs of the eight lives lost and more than 200 people injured in last week's derailment in Philadelphia.
That payout cap for a single passenger rail incident was part of a late effort in 1997 to pass a law that would rescue Amtrak from financial ruin and help it one day become independent.
Adjusted for inflation, which the law does not consider, that amount would be just under USD 300 million now. And Amtrak is still far from independent.
The Philadelphia crash could be the first time the liability ceiling designed specifically for Amtrak would actually apply to the railroad.

It's not known how high the costs of victims' deaths and injuries from Tuesday's crash will run.
The train, which left Washington headed to New York, was moving at more than twice the speed allowed on a curve when it derailed not long after it stopped at Philadelphia's 30th Street Station. Investigators haven't determined why the train was traveling so fast.
"I don't think Amtrak has ever faced a situation like this, and since they own the Northeast Corridor, they're 100 percent on the hook," said Frank Wilner, author of the book, "Amtrak: Past, Present, Future."
Using past passenger rail accidents as a guide, some lawyers expect damages from the crash to be similar to a 2008 accident in Los Angeles, which resulted in a USD 200 million payout to victims.
The money was paid to victims by Metrolink, which provides commuter rail service in Southern California, and Veolia Environment, a French company that operated the rail service at the time.
A judge divided the USD 200 million among the victims, with sums between USD 12,000 and USD 9 million. In some cases, lawyers said the amounts were far less than the projected costs of medical care needed as a result of the crash.
