20 FEBRUARY 2009 The Prince of Wales had a chuckle when Camilla got an unexpected steam clean as the royal couple christened a railway locomotive in York.
Clouds of smoke drifted their way as they prepared to name train and for a few seconds the Duchess of Cornwall was completely engulfed, sending Charles into gales of laughter.
Luckily his wife saw the funny side, too, and giggled at her Brief Encounter moment at the city's historic station. The new Peppercorn class A1, named Tornado, is the first mainline steam-engine to be built in Britain for 50 years.
Locomotive enthusiasts raised £3 million to fund the train, which will run on the East Coast Main Line.
