This is the hilarious moment a DJ turned a train carriage full of Aintree racegoers into a rave.<br /><br />The footage, captured on Thursday (April 12), shows people jumping and singing along to the music in the middle of the train.<br /><br />Although the carriages are empty at first, they quickly fill up with fans of the horse-race, which takes place at Aintree in Liverpool.<br /><br />Passengers dance along to the music, played by internet prankster Lee Marshall. <br /><br />Even staff at railway company Merseyrail seem to be enjoying the fun. <br /><br />At one point, a rendition of dance group Vengaboy's classic hit "Boom, Boom, Boom, Boom!!" lights up the carriage. <br /><br />The Grand National race is set to run on Saturday afternoon, with more than 40 runners and riders taking part.<br /><br />Ladies' day took part this Friday 13.
