Le Train Bleu ("The Blue Train") is a restaurant located in the hall of the Gare de Lyon railway station in Paris, France.
 It was designated a "Monument Historique" in 1972.
The Blue Train Races were a series of record-breaking attempts between automobiles and trains in the late 1920s and early 1930s.
 It saw a number of motorists and their own or sponsored automobiles race against the "Le Train Bleu", a train that ran between Calais and the French Riviera.
 The rationale to beat the train was to compare the contemporary automotive performance with locomotive dominance; to showcase recent progress achieved by cars regarding reliability, durability, speed and comfort; to promote the cars, their marques and the adventurous persona of their drivers; and to establish automobiles as a viable and aspirational mode of transport for the individual traveller.

Hidden Agenda is a 1988 computer strategy game with menu-driven interface and early, black and white graphics whose scenario was designed and written by Jim Gasperini, with input from project consultant Eric Ehrmann.
 While the scenario was implemented in text form, the game made use of an innovative graphical interface, with naturalistic characters, settings, and digital video interstitials.
 The narrative simulation system was designed and implemented by Greg Guerin and Ron Martinez (who also produced the game).
 Ron Martinez also designed and implemented the front end user experience, in the process inventing one of the first implementations of digital video with frames grabbed from a hacked four-head VCR.
 The game was intended to simulate the conditions of a post-revolutionary Central American country.
 It is considered a forerunner of the Games for Change movement, alongside other early Macintosh games including Chris Crawford's "Balance of Power".
The Calais-Mediterranée Express was a luxury French 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.

Le train bleu is a one-act ballet choreographed by Bronislava Nijinska to music by Darius Milhaud for Serge Diaghilev's Ballets Russes, based on a scenario by Jean Cocteau.
