Say what? Amtrak didn't have $$$$ to pay a bribe. They don't have $$$$ to do the things they need to do to improve the infrastructure. Blame Congress for that.
The NTSB does a thorough job and will not say anything until they have the facts. Obviously they have not come to a conclusion as to what happened in the cab.
Amtrak is waiting for their findings, unlike the general public & politicians & media.
