We have the largest train around. If you plan to have the Trackless Train at your event, you must plan on it being the biggest attraction for young kids. Map out a path that you would like the train to take. Make sure the path is not where people will want to walk across. A child must be 30 inches or taller to ride the train without an adult with them. The maximum weight per train car is 600 pounds. There should be no more than 3 children or 2 adults per seat.
