摘要

The wall has horizontally arranged insertion panels (2) that are interposed in I-beam-shaped guide rails (1). The guide rails inwardly tilt in an upper region approximately in a circle segment shaped to a platform. The guide rails are positioned under observation of a predetermined safety margin for forming an accessible protection and manipulation area. The guide rails tilt according to an interior space, and marginally end before the boundary of the interior space of a train set. A safety bar (3) is detachably attached at the marginal end.
