Vice President Joseph R. Biden Jr. will be leaving Washington the same way he entered it: by Amtrak.

In a tweet sent Tuesday, the outgoing vice president wrote, “Jill and I will head home to Delaware the same way I have for 44 years: by train.”

Jan 20, Jill and I will head home to Delaware the same way I have for 44 years: by train. Serving this country has been our greatest honor. pic.twitter.com/D0g2rEvE9R — Vice President Biden (@VP) January 10, 2017

Biden’s loyalties to Amtrak took shape during his time as a freshman senator from Delaware.

In the wake of a tragic car accident that claimed the lives of his first wife and infant daughter in December 1972, only a few weeks after he first won election to the Senate, Biden contemplated giving up his seat to instead stay home with his sons, Beau and Hunter.
