Son of beast is torn in 2013

A defunct roller coaster refers to a roller coaster that has ceased its operation and wasn't relocated to another amusement park. Defunct roller coasters, after closure, are usually either demolished, or sold for parts. Amusement parks can also be defunct, if they close down.

Not to be confused with standing but not operating (SBNO).
