Yeah, there was an article on this a few months ago.Listening to BBC last night they said that amtrak in the north east is the big money maker and subsidizes the rest of the system in the US. They are supposed to install these boxes that control train speeds and haven't, congress also cut funding to amtrak even though it's a money maker unlike most of our govt boondoggles.
AMTRAK needs SERIOUS funding.
