Prince Charles, Camilla Ride The London Underground To Mark Birthday (PHOTOS)

Prince Charles and his wife, Camilla, Duchess of Cornwall, took the London Underground early Wednesday morning to celebrate the famed subway's 150th birthday (London's first line opened January 10, 1863.)

Shocking commuters, the two royals hopped on a Metropolitan train line from Farringdon to King's Cross (a ride which takes 3 minutes, according to The Telegraph); it was reportedly the first time Prince Charles had been on the Tube in roughly 35 years, according to

When the duo disembarked at the famous King's Cross station, they stopped to check out Platform 9 3/4 (from "Harry Potter," in case you didn't know), which received a permanent home in the New Western Departures Concourse in March 2012.

There's no word as to why the royals waited until the end of January, instead of the actual birthday, to ride that rail.
