Wilmington, Delaware/Washington - There was a moment of hesitation Saturday before vice-president-elect Joe Biden knocked on the door of the Amtrak Pullman coach.
Biden was looking to board the historic inaugural train, which carried president-elect Barack Obama on the historic final journey towards Washington and his inauguration on Tuesday.
But no one answered, and he opened and stuck his head through the door on the last car on the train, as if to say "anyone home?" broadcast images showed.
