The present invention prevents a reduction of a transport force in a section where high travel energy is required. A transport path 401 includes an assistance-required section 410 in at least a portion. A banknote transport system 10 includes an assistive force application section 803 arranged adjacent to a section of an air flow path 101 along the assistance-required section, and an assistive body 900 that travels in the assistive force application section. The assistive body includes an assistive body magnet 901. The banknote transport system 10 applies an assistive travel force to a moving body 200 using a magnetic force acting between the assistive body magnet and moving body magnets 213 and indirectly assists a transport force of a transport body 500.

A logistics service system may include at least three tubes, and a carrier configured to hold goods items. The carrier may be provided with a permanent magnet. Means for propulsion of the carrier may be provided in the tubes. A control unit may be provided. A switching device may be arranged to connect a first one of the tubes with a second and a third tube. The switching device may be configured to redirect the carrier from the first tube into the second or the third tube. The switching device may include electromagnets provided along the second and the third tubes. The control unit may be configured to activate the electromagnets of one of the second or the third tube, into which the carrier is destined, to guide the carrier into an intended tube.
