What is the average mass of a roller coaster?

There is no one average mass for a roller coaster, as they can vary greatly in size and design. However, some of the largest roller coasters in the world can weigh up to several hundred tons. For example, the Steel Dragon 2000 at Nagashima Spa Land in Japan weighs 450 tons, while the Kingda Ka at Six Flags Great Adventure in New Jersey weighs 305 tons.
