This disclosure describes an electromagnetic system for efficient propulsion, suspension, and guidance. The track is inexpensive totally passive steel. This linear form of the D.C. motor provides traction motor characteristics without physical contact, The moveable element (vehicle) comprises both the integrated armature and field magnet flux source which induces magnetizing flux into pairs of rails each energizing a set of interdigitated poles of alternating polarity in the track against which its own armature conductors interact for thrust and braking. This source of magnetic flux requires no power and provides passive suspension at any speed and, with control, guidance. The permanent magnet and control flux in common airgaps multiply the effectiveness of lateral control for magnetic stabilization and to restrain external forces.
