To provide an easy, positive and low-cost shunting apparatus between a guideway main line and an incoming line of a maintenance vehicle for a superconductive magnetic levitation type railway.

Movable girders 1a, 1b are disposed in the suitable positions of two upper and lower guideway main lines 50 laid keeping a suitable space, so as to be independently turnable around pins 6 installed at the lower parts of the guideway main lines 50, within the horizontal planes. The two upper and lower guideway main lines 50 are provided with the incoming lines 3a, 3b in proximity. The movable girders 1a, 1b constitute part of the guideway main lines 50 in the case a linear vehicle travels on the guideway main lines 50 and are normally connected and fixed to the guideway main lines 50. Panels 56 mounted with jacking coils, levitation guide coils, or the like are fixed to sidewalls 30 of the movable girders 1a, 1b.
