Obama is following the path Lincoln took for his Inauguration in 1861 and will be stopping along the way to greet citizens who come out to see the President-Elect. 16 families that Obama and Vice-President-Elect Joe Biden met during the campaign will join the two men on their train ride into the nation's capital.
Obama will make a few stops along the 137-mile journey, including a stop in Wilmington, Delaware where he will pick up Joe Biden and his wife.
There is unprecedented security in place for Obama's trip to Washington, as well as the inauguration festivities taking place starting today through next week.
As many as two million people are expected to descend on the national mall to be a part of this historic inauguration.
