The Calais-Mediterranée Express was a French luxury night express train which operated from 1886 to 2003. It gained international fame as the preferred train of wealthy and famous passengers between Calais and the French Riviera in the two decades before World War II. It was colloquially referred to as Le Train Bleu in French (which became its formal name after World War II) and the Blue Train in English because of its dark blue sleeping cars.
