Abstract: A retractable step system for getting into and out of a vehicle has at least one step and a supporting element, which carries the step and is movable between a raised position and a lowered position; in the lowered position, the step projects from the supporting element along a first horizontal axis so as to allow a user to place a foot on it; the system has a control member, which can be manually operated, and a stop device, which holds the supporting element in the raised position, when the control member is arranged in a first position, and allows the supporting element to freely move to the lowered position, when the control member is arranged in a second position; the control member has a retention portion, which, in the second position, projects along a second horizontal axis, which is orthogonal to the first horizontal axis, so as to keep, in use, a vehicle door open.

Abstract: An electric motor assembly for railway drive. The motor assembly comprises: an electric drive motor; a ventilation and cooling device for ventilating and cooling the electric drive motor through cooling air; and a draining device to drain the ventilation and cooling air flow. The draining device is provided with a silencer device for the cooling air flow. The silencer device comprise at least one straight channel to reduce the turbulent flow into a substantially laminar flow of the out-flowing ventilation and cooling air. Furthermore, the draining device comprises a scroll, which consists of two separate arched channels in order to avoid the formation of stationary vortices. The two arched channels communicate with one another, from the fluidic point of view, only in a common outlet area for the ventilation and cooling air.

Abstract: A floor structure is provided with an underframe, which is part of a carriage body, is elongated along a longitudinal axis coinciding with the advancement axis of such carriage, and has a plurality of longitudinal attachment rails arranged on an area of the lower surface of the underframe; the attachment rails project downwards so as to define therebetween a plurality of compartments, which are engaged by panels having insulating material to form a fire protection system; such a system has, furthermore, a plurality of section bars, which are attached to the attachment rails and are shaped so as to retain the panels in fixed positions in the compartments and, at the same time, cover the attachment rails.
