    You dash through a crowded railway station, tripping over bags, spilling (泼出) your coffee, only to have the doors slide shut in your face, leaving you breathless on the platform as the train pulls away,

    But at least, if you're in France, someone may be playing the piano for you. But it won't be performed by a paid musician, or even a street entertainer playing for coins. It will just be a random passer - by, jamming for the fun of it on one of the pianos that the national railroad company, S. N. C. F., has fixed in nearly 100 stations across France. They are free for anyone to play, and travelers from all walks of life have taken to doing just that.

    Gares & Connexions, the S. N. C. F. division that manages its stations, rents the instruments from the producer, Yamaha: which maintains them and tunes them every month or two. The first one was set up in the Gare Montparnasse in Paris in 2012.

    The music, mixed with the sounds of shouting passengers, screaming trains and rolling suitcases, gives French stations a special soundscape. The amateur musicians have included Irish soccer fans and even babies. In 2014, Gares & Connexions and Yamaha organized a nationwide contest called Your Turn to Play, asking participants to submit videos of themselves using one of the pianos. It drew nearly 900 entries.

    Isn't the railroad company taking a big chance? Apparently not: “None of the instruments has been vandalized to this day, or even merely damaged,” said Claire Foumon, a spokeswoman for Gares & Connexions. “They are shared and respected by all.”

    So if you miss a train in Paris; Bordeaux or Marseille one day, perhaps someone will be playing a favorite piece that will ease your pain. Or perhaps you'll sit down and play your annoyance away yourself.
