While Miniatur Wunderland in Speicherstadt, Hamburg was closed to visitors due to the pandemic, the employees used the world’s longest model train railway with a little red train to play a number of classical songs by tapping glasses of water filled at varying heights. The train ran over 220 meters, the length of the miniature park, and used thousands of glasses. This project was rather time-consuming, but in the end, it was awarded the Guinness World Record for the “Longest Melody Played by a Model Train”.
