As thousands of Londoners made their way back to work today after the holiday break they were joined by an unlikely fellow commuter, the Duke of Cambridge.

Prince William began his first day of a special 10-week course at the University of Cambridge and the royal heir got to school not by a private chauffeur or even the school bus, but by train.

William, 31, boarded the 9:44 a.m. train at London's King Cross station this morning, according to The Associated Press.

The duke, who left wife, Kate Middleton, and 6-month-old son, Prince George, back home at Kensington Palace, was greeted at his new school, St John's College, by vice chancellor Sir Leszek Borysiewicz and other school officials, reports the U.K.'s Telegraph.

The executive education program, which will end in mid-March, consists of seminars, lectures and meetings, Kensington Palace said last month.

"The course has been designed to help provide the Duke with an understanding of contemporary issues affecting agricultural business and rural communities in the United Kingdom," the palace said in a statement.
