"Le Train Bleu" (lit. "the blue train"), officially the Calais-Méditerranée Express, was a luxury French night express train which carried wealthy and famous passengers between Calais and the French Riviera from 1922 until 1938. It was colloquially referred to as "le train bleu" in French and the Blue Train in English because of its dark blue sleeping cars, and became formally known as "Le Train Bleu" after World War II.
