Abstract
A system and method for guidance control on a wheeled bogie is disclosed herein. An electromagnetic engine may be coupled to the wheeled bogie such that the electromagnetic engine may generate magnetically attractive forces between the electromagnetic engine and the rail. The generated force may be used to increase traction for braking and climbing operations. Further, the generated force may be used to counteract hunting oscillation. Still further, the generated force may be used to counteract lift generated by the wheeled bogie operating in a turn with cant.

An electromagnetic engine coupled to a wheeled bogie configured to operate on a plurality of rails, the electromagnetic engine comprising:
- a steel core, the steel core having an outer prong, a center prong, and an inner prong, the outer prong having a first base, the center prong having a second base, the inner prong having a third base;
- an outer coil, the outer coil being disposed about the outer prong;
- an inner coil, the inner coil being disposed about the inner prong, the inner prong being longer than the center prong and further being configured to substantially align with a profile of a flange belonging to a wheel assembly coupled to the wheeled bogie;
- a center coil, the center coil being disposed about the center prong, the center coil further substantially overlapping the outer coil and the inner coil, the center coil further being disposed more proximal to the second base;
- and
- a controller configured to control the outer coil, the inner coil, or a combination thereof.
