Abstract
A movable step displaceable by means of an operating mechanism between a withdrawn position and a service position has an extension in the form of two transverse arms associated with two pairs of link-arms which are pivotally mounted on four shafts having horizontal and parallel axes. Two shafts are stationarily fixed on the floor of the railway car, the second shaft being set back from the first with respect to the car wall. The other two shafts are movable and attached respectively to the transverse arms near the point of connection of these arms to the step, and to the transverse arms at the ends which are pivotally attached to the rear link-arms. Stable immobilization of the step is achieved in the service position as a result of abutting application of the articulations of the transverse arms and of the rear link-arms against a stop.
