How about vetting this one

Riehl World View has an interesting piece on the Amtrak travel on one Senator Biden.

Apparently, Sen. Biden has been running many of his Amtrak tickets through his own failed campaign.

Update: To be clear - this is election travel expense data. But it gives a general idea of what Biden's AMTRAK travel costs run. And some of them require some explanation - perhaps buying multiple tickets in advance on the same day?
