Obama completes train tour; presidency looms ahead

Barack Obama has arrived in Washington at the end of a majestic train ride across the frigid mid-Atlantic seaboard, moving another step closer to the presidency. Celebratory crowds braved subfreezing weather to salute Obama along his 220-kilometer journey to the nation's capital from Philadelphia. Obama often couched his moment of triumph in sobering words, saying the country is burdened by staggering problems like the economy, global warming and war. He will take the oath of office in three days, succeeding George W. Bush.
