"Decorated" threshold cross on the occasion of a line closure

A sleeper cross is a device for the provisional blocking of a track with a ballasted superstructure, into which it is no longer possible to drive due to closure, construction work or the like. It consists of two loose wooden railway sleepers that are slanted into the track grid so that one end of both sleepers is stuck under one of the two rails and the other end rests on the other rail. Often a threshold cross is also supplemented by a protective board.
