An overhead railway comprises a track consisting of an elongate box-section member 11 having a longitudinal slot 10 through one side thereof, and a vehicle adapted to run along the track and having at least one bogie having a portion extending into and retained by said track. The bogie preferably mounts wheels 21 running on said one side, retaining wheels 22 within the channel, and a wheel 23 located horizontally within the slot to provide lateral positioning on the track. A point for this railway, has a pair of slots 51, 52 diverging from a single slot 50 and, at the point of divergence, a pair of curved blades 54, 55 mounted so as to pivot together between first and second positions. Figure 8 shows an alternative point design, with a single movable blade 84. Linear motors (Figs. 18, 19) may be used with magnetic levitation. The system may be used to transport hospital patients (Figs. 13, 15). Trains of chairs may be coupled together by couplings 125 (Fig. 12). <IMAGE> |
