A drive arrangement 1 moves a body 2 along a path 3 with respect to first 4 and second 6 media guides. The first media guide conveys a medium 5 at a first velocity 8 along the path and the second media guide conveys the medium 7 at a second velocity 9 different to the first velocity along the path. The drive arrangement is configured to (a) interact with the medium of the first media guide to extract energy and develop a reaction force against the first media guide for driving the body along the path, and (b) interact with the medium of the second media guide by means of energy extracted from the medium of the first media guide to develop a reaction force against the second media guide for driving the body along the path. The drive arrangement may comprise an energy store 10 to store energy extracted from the media of the first and second media guides. The first and second media guides may comprise a set of electromagnetic coils and the media may be magnetic field waves. The medium of the first and second media guides may be a moveable tangible object such as a belt.
