Just how long is it? Well, we are talking about a whopping 4,000.25 m (13,124 ft) here (which would mean approximately four kilometers in total), and the entire feat was achieved using 93,307 pieces. Obviously, the record keepers over at Guinness approved at this world record attempt, where the Lego train engine actually took all four hours in order to complete its epic journey from one end to the other. Since Lego bricks are not the cheapest thing in the world to indulge in, Ludvigsen actually placed ads in newspapers and online to ask for more blue track, and obviously, the public was generous enough to help Ludvigsen achieve his dream.
