The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necessary, capitalization should be fixed.
Mag-Trains (short for magnet trains) were seen on rails throughout Metropolis, on which Ratchet could grind in parts of the city's transit system. In Ratchet & Clank Future: Tools of Destruction, as Ratchet made his way toward the defense center, were areas where he had dodged speeding magnet trains that came at him while he used the rails for transportation, along with other obstacles. Some of the rail lines were destroyed because of the attack on Metropolis by Tachyon's troops.
