After his day long journey Obama and his family with Vice-President Elect have arrives at Union Station.
US President-elect Barack Obama is retracing the steps of Abraham Lincoln as he travels from Philadelphia to Washington to assume the presidency.
On Saturday, Mr Obama and his family boarded the train to Washington shortly before 1100 (1600 GMT).
The train is passing slowly through towns so Mr Obama can greet crowds.
Along the way, people gathered in Baltimore, Maryland to hear him speak and he called on them to show resilience in tough times.
The trip mirrors the journey Mr Lincoln made as he travelled to Washington in 1861.
