Prince William and Kate Spotted in London Train Station

— -- The Duke and Duchess of Cambridge appeared just like any other young parents returning home after a quick country trip away as they rushed through one of London’s busiest train stations Friday.

William and Kate, both 32, caused a few double-takes as fellow travelers spotted them beneath the baseball caps they each paired with casual clothes while carrying their own bags through the rush-hour crowd at London’s Kings Cross station.

The Duke and Duchess were spotted traveling with their beloved dog, Lupo, but without their 1-year-old son, Prince George.

“It doesn’t surprise me at all,” said ABC News’ royal contributor, Victoria Murphy, of the high-profile couple’s low-profile means of travel. “I think that they are very keen to do things in the most efficient way and also in the most cost-effective way and I think that they want as little fuss as possible.”

“They think like other people: What’s the best way to get from A to B,” Murphy said.

The royal couple was believed to be traveling home from Norfolk, the site of their country home, Anmer Hall, where they will be living when Prince William begins his new job as an ambulance helicopter pilot.

William and Kate were also spotted out together on a date night during their time away. The royals were reportedly seen walking hand-in-hand into a local pub that Prince William had driven his wife to himself.

Kate has reportedly been busy decorating Anmer Hall, a gift from the queen for William’s 30th birthday, to make it a home fit for two future kings. The 10-bedroom mansion is based on the queen’s 20,000-acre private Sandringham estate in Norfolk, close to the East Anglian Air Ambulance service, where Prince William will work.

The home is in the final stages of a two-year renovation, including a large conservatory for the family. It already includes a pool and tennis court and renovations are said to have reportedly added accommodations for protection officers and Prince George’s nanny.

Prince William will begin a five-month training period for his Air Transport Pilot’s license this month, the palace has said.
