maglev

adj

1. (not-comparable)Describing a train, system, etc, that operates by magnetic levitation.

   “A “moving platform” scheme[…]is more technologically ambitious than maglev trains even though it relies on conventional rails. Local trains would use side-by-side rails to roll alongside intercity trains and allow passengers to switch trains by stepping through docking bays. This set-up solves several problems […]. Stopping high-speed trains wastes energy and time, so why not simply slow them down enough for a moving platform to pull alongside?”

   “After nearly three years of technical research, Ding said the team had developed a lightweight and high-strength train body that lays the technical foundation for the development of five sets of maglev engineering prototypes.”

noun

1. A train supported by magnetic levitation.

   “When finished, the trains will be the fastest commercial maglevs developed and built completely by Chinese firms.”
