Errrr...Acela runs from Boston to Washington. There is no overhead wire in the rest of the country.
You must mean Amtrak. And, if the candidates counted on Amtrak to carry them across the country, they'd risk running up to 24 hours behind schedule. And being insulted when they asked why.
Which is to be expected, since Amtrak is run by the government.
Better off to rent a convoy of stagecoaches...
I'll go with that.
