Britain's Queen Elizabeth II is shown round the carriage of a parked train at Baker Street underground station in London, for a visit to mark the 150th anniversary of the London Underground, Wednesday, March 20, 2013. The Queen made her first public engagement in more than a week Wednesday after cancellations following her hospitalization for a stomach bug. The British head of state joined her husband Prince Philip and their granddaughter-in-law, Kate, for the event marking the 150th anniversary of London's sprawling subway system, affectionately known as the Tube.
