The invention provides in some aspects a transport system comprising a guideway with a plurality of propulsion coils disposed along a region in which one or more vehicles are to be propelled. One or more vehicles are disposed on the guideway, each including a magnetic flux source. The guideway has one or more running surfaces that support the vehicles and along which they roll or slide. Each vehicle can have a septum portion of narrowed cross-section that is coupled to one or more body portions of the vehicle. The guideway includes a diverge region that has a flipper and an extension of the running surface at a vertex of the diverge. The flipper initiates switching of vehicle direction at a diverge by exerting a laterally directed force thereon.
