first we don't know the cause of this particular incident so we don't know whether it was speed or something to do with the infrastructure itself but we do know that we haven't done enough on permanent financing for our infrastructure in this country. the first thing we need to do is pass a six year reauthorization service transporg act. it's got to be at a level to make the type of improvements in our system that the american public need and our economy needs. and then we have to make sure we have the rvevenues to pay for that so we don't go into debt. there's bipartisan support for this so we should bring it up let's vote on it. it's timely because the current transportation fund runs out of authorization at the end of this month. we've got to act this month. >> how do you reassure passengers especially in the northeast, that it's safe to get on a train right now? >> well, i'm going to tell you this. we're going to find out what happened we're going to make the investigation totally transparent so everyone knows exactly what happened. we're going to keep this investigation very public.
