You are refering to a LIM device or Linear induction motor. This is the device use to power Maglev Trains, or roller coasters such as superman, or Wicked twister. It works by turning on a super-conducting electromagnet in front of a vehicle, attracting it, and a identicle magnet behind it repel the vehicle. As it moves down the track the magnets turn on and off in front of a behind the vehicle to accelerate it to very high speeds. Superconductor electromagnets use a relatively low amount of energy. I know with Maglev trains, a full train can float above the track using less electricity than it takes to run the air conditioning.
Rail guns use this technology to accelerate projectiles to supersonic speeds and allows them to go through nearly anything. The perfect weapon.
